Answer: AMSOIL introduced the first synthetic motor oil with an API (American Petroleum Institute) Service Classification in 1972. Since that time, AMSOIL has varied and expanded its product line.

Answer: AMSOIL Synthetic Motor Oil can be used during break-in trouble free. In fact, vehicles such as Dodge Viper and Chevrolet Corvette come factory filled with synthetic oil.

Since most new vehicles come filled with petroleum oil, it only makes good sense to change to AMSOIL at the first scheduled oil change interval. New engine components generate high levels of wear metals and can contain contaminants from assembly. By allowing the engine to operate with the petroleum oil until the first oil/filter change interval, the wear metals and contaminants are removed prior to installing AMSOIL.

Answer: Absolutely not. Switching from petroleum oil to AMSOIL in routinely maintained vehicles will not cause clogged oil filters or passageways, regardless of mileage. Sludge, which is caused by poor quality oil and neglected maintenance practices, would have to be present in significant amounts to plug oil filters and passageways. If this excessive amount of sludge is present in an engine, it is just a matter of time before oil filters and passageways clog, regardless of the installation of AMSOIL.

Answer: In modern vehicles, there is no risk of AMSOIL motor oil leaking. In fact, AMSOIL motor oil is fully compatible with modern seal materials. It is properly formulated to condition seals, keeping them pliable to prevent leakage.

Answer: Absolutely not. Congress in 1975 enacted the federal Magnuson-Moss Act to regulate written consumer product warranties. An examination of the law reveals warranties remain intact when AMSOIL Synthetic Lubricants are used. Click here for the full details.

Question: I have a 2001 Ford F-350 Pickup with a Powerstroke Diesel with 7000 miles. I'm getting ready to change over to synthetic oil. What AMSOIL motor oil would you recommend to use?

Answer: It is recommended that you use either AMSOIL Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD) or AMSOIL Synthetic 15W-40 Heavy-Duty Diesel and Marine Motor Oil (AME) for this diesel application. HDD is the preferred choice for better fuel economy, cold weather performance and mixed gasoline and diesel engine fleets. It provides better protection compared to conventional 15W-40 mineral based oils with its superior film strength and enhanced anti-wear additives. AMSOIL AME is a premium oil that matches many manufacturers viscosity recommendations. It outperforms competitive 15W-40 oils and is a lower cost option compared to AMSOIL HDD.

Answer: Absolutely! AMSOIL AFF 0W-40 was specifically formulated for use in small, hard working 4-stroke engines. AFF is ideal for 4-cycle snowmobiles, ATV's, personal watercraft, 4-stroke boat motors, lawn equipment etc.

Answer: AMSOIL AFF can most certainly be used in cars or trucks but it is not our first choice for automotive applications. We offer a full line of automotive oils. AFF is specifically formulated for small recreational 4-stroke engines, and is an excellent choice for 4-Stroke outboards, ATVs, lawn equipment, snow blowers etc.

Answer: AMSOIL synthetic oils can be recycled in the same manner as a petroleum-based motor oils. Synthetic oils can also be used in furnaces designed to burn waste oils.

Answer: AMSOIL Synthetic Lubricants are fuel efficient, extended life lubricants manufactured from select synthetic base stocks and special purpose additives. These lubricants provide improved overall performance characteristics when compared to conventional petroleum oils.

Answer: As the developer of the world's first API qualified synthetic motor oil in 1972, AMSOIL has gained more experience than any other oil company in formulating automotive synthetic lubricants. It is this extensive experience that provides the ability to maximize product performance through use of a full range of high-performance synthetic base oils, most notably polyalphaolefin (PAO).  AMSOIL views synthetic base oils the same as it views additives, with each having its own set of unique properties.  AMSOIL engineers its lubricants with the synthetic base oil or combination of base oils best suited to a specific lubricant’s application demands (gasoline, diesel, racing, transmission, gear, extended drain, extreme temperature, etc.). 

AMSOIL INC. maintains an unwavering commitment to provide products that outperform the competition and deliver maximum benefits to all AMSOIL customers. Performance is the bottom line.

AMSOIL Synthetic Blend Motor Oils are a blend of synthetic fluids and petroleum oils. They are combined to form an all season motor oil that demonstrates many of the performance features of synthetic lubricants.

AMSOIL Motor Oils may be used in any mechanically sound gasoline or diesel fueled engine. Basically, that means they are excellent for use in any vehicle’s engine.

Absolutely not! Manufacturers’ warranties are based upon the use of oils meeting specific API Service Classifications, for example, SJ/CF. (AMSOIL lubricants meet the current API Service requirements and, thus, are perfectly suited for use in any new vehicle without affecting the validity of the new vehicle warranty.) 

Synthetic oils are made to protect and perform better than petroleum oils at both high and low temperature extremes. That’s why every jet engine in the world is lubricated with synthetic oil. AMSOIL Motor Oils have extremely low pour points and flow readily at extremely low temperatures for easier winter starting and significantly reduced engine wear. At high temperatures, no conventional motor oil can compare to the overall protection AMSOIL Synthetic Motor Oils provide. That’s extremely important for today’s turbocharged and small, non-turbocharged engines!

AMSOIL synthetic motor oils are fully compatible with all petroleum motor oils, and there is no danger in mixing the two. Mixing AMSOIL and petroleum oil, however, is not a recommended as a general practice. Performance and long drain intervals will be sacrificed and the oil should be promptly changed, at maximum, within the next 3,000 miles.

AMSOIL Synthetic Motor Oils are highly resistant to the destructive effects of heat, and do not break down like petroleum oils. This means that AMSOIL Motor Oils can provide much longer drain intervals than conventional lubricants.

Yes. When used in mechanically sound engines, AMSOIL Motor Oils can reduce oil consumption. Under test conditions, a reduction of as much as 42% was demonstrated for prolonged periods. However, this should not be taken to mean that AMSOIL Motor Oils are “cure-alls” for engines that consume oil because of mechanical problems.

There are no special requirements; however, in older vehicles or those with high mileage, it may be advisable to use AMSOIL Engine Flush first. This will ensure that the engine is clean and free of any accumulated contaminants which might have an effect on the service life of AMSOIL Motor Oils. In all cases, it is good judgement to install a new AMSOIL Absolute Efficiency Oil Filter (EaO) every time you change oil.

No, they are not necessary! AMSOIL Motor Oils are properly formulated under the strictest Quality Control procedure to provide superior lubrication performance.

Q.	Is the principle of operation of the BMK-18 the same as the BMK-13, BMK-15, BMK-16, and BMK-17?
A.	Yes, the principle is exactly the same. For a given volume of oil being filtered at one time, the full flow filter filters approximately 80-85% of the oil, while the by-pass filter filters approximately 15-20% of the oil.
Q.	What are the recommended applications for the BMK-18?
A.	Gasoline powered inboard and inboard/outboard engines and light-duty diesel inboard engines. For specific applications consult the AMSOIL website or the Adapter Kit Application Guide (G-2051).
Q.	Is it necessary to install marine filters when using the BMK-18?
A.	Marine filters are manufactured with an extra measure of corrosion resistance, but using a marine filter is not necessary when following the prescribed filter changes outlined in the BMK-18 instruction sheet. (BP-239)
Q.	Must I order a separate adapter fitting when I order a BMK-18?
A.	Yes. A spin on adapter kit must be ordered that matches your application as found in the Applications Guide (G-2051). There are four options: BK-195 (3/4" x 16 thread) BK-196 (13/16" x 16 thread) BK-197 (18 mm x 1.5 thread) BK-198 (20 mm x 1.5 thread
Q.	Why is the BMK-18 more expensive than the other Dual Remote By-Pass Systems?
A.	The BMK-18 is designed to be installed in harsh marine environments. The hose fittings are coated with a 3 ml layer of Alumiplate™ and 1 ml of zinc and yellow chromate. Standard hydraulic fittings typically survive for 96 hours in the grueling ASTM B-117 Salt Spray Test. When we subjected the Alumiplate™ coated AMSOIL Marine Bypass System fittings to this critical corrosion resistance test protocol, they lasted over 1,000 hours! This means the Alumiplate™ coating on the fittings of the AMSOIL Marine By-Pass Filtration System is 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings! While this exclusive Alumiplate™ coating process is expensive, AMSOIL felt this extra margin of system protection was absolutely necessary to provide marine application customers with extraordinary corrosion resistance and protection - and the peace of mind that goes with knowing that the AMSOIL Marine By-Pass System is engineered for demanding marine applications. Also, the fasteners and mounting bracket are stainless steel, and the hoses are larger diameter stainless steel braided and U.S. Coast Guard approved.
Q.	Where do I apply the anti-seize compound that is supplied with the kit?
A.	Apply a small amount on the swivel end of each hose end fitting and on the adapter retaining nut to avoid seizure.
Q.	Where do I apply the thread sealant?
A.	On threaded connectors that are mounted to the filter mount assembly and the spin on adapter.
Q.	Is the entire BMK-18 unit U.S. Coast Guard approved?
A.	No, only the hose is U.S. Coast Guard approved. The other components, designed for marine environments, are not regulated by the Coast Guard.
Q.	Can I use the BMK-18 in a vehicle other than a boat?
A.	Yes, you can mount the BMK-18 onto any engine that will accept the appropriate adapter and where room permits.
Q.	Can I order replacement parts for the BMK-18?
A.	Yes. Replacement parts are available at this point. However, it must be ordered through our Superior product center at this time.
Q.	Can I use the AMS-Oiler with the BMK-18?
A.	Yes. The AMS-Oiler AMK-01 can be mounted directly on the BMK-18. The AMK-02 can be mounted independently of the by-pass unit through an engine lubrication port or via teeing off of the oil pressure sending unit.
Q.	Many salt-water boats have diesel engines. Does AMSOIL make a by-pass system for them?
A.	The BMK-18 can be used with many of the smaller diesel engines. As long as you can match the filter thread size with the adapters available from AMSOIL, the system can be used.
Q.	Does the BMK-18 remove water from my oil?
A.	The by-pass filter isolates small amounts of moisture and condensation from the oil stream.
Q.	How does the BMK-18 compare to other marine by-pass systems?
A.	The BMK-18 is unique due to the fact it has individual adapters for each filter thread size. Also, the AMSOIL Marine By-Pass has a combination of full flow and by-pass filters in one unit. Most other by-pass filter units do not have a full flow filter associated with the unit.
Q.	What filter sizes come on the BMK-18? How do I know which is best for my application?
A.	The BMK-18 does not come with filters. Depending on clearance available, AMSOIL recommends either the EaBP-90, EaBP-100, and EaBP-110 By-Pass Filters and any AMSOIL full flow filter with a ¾" x 16 thread. Preference would be given to the AMSOIL EaO-15 or the larger EaO-26. To provide maximum protection, AMSOIL recommends the installation of a filter that is large as possible for the area available.

Can AMSOIL Motor Oils be used in any engine?

Certainly, AMSOIL Motor Oils may be used in any mechanically sound gasoline or diesel fueled engine. Basically, that means they are excellent for use in any vehicle’s engine.

When is the best time to switch to AMSOIL?

Switching a vehicle to AMSOIL synthetic motor oil is fairly simple, but there are a few things you need to be aware of. First, if you have a brand new vehicle we recommend that you run a short cycle of petroleum oil on a gas engine passenger car or light truck (typically 500 miles) and approximately 5000 miles on a diesel engine before installing AMSOIL. This doesn't mean that you can't install AMSOIL sooner, as many OEM's install synthetics as a factory fill, it simply means these are our recommendations based on our extensive engineering studies and knowledge of this topic. Check out this page for more information on Switching to Amsoil .

Should I use an oil additive like Slick 50 when using AMSOIL

Absolutely Not! AMSOIL has long discouraged motorists from using any kind of aftermarket lubricant additive. After all, AMSOIL synthetic lubricants use the finest quality synthetic basestocks and additive systems. AMSOIL motor oils are formulated under the strictest quality control standards to provide superior lubrication performance. Additives cost money and only detract from the quality of AMSOIL motor oils.

A perfect example of why AMSOIL discourages use of aftermarket additives is the Federal Trade Commissions (FTC) recent lawsuit against zMax auto additives, seeking to halt false and misleading advertising and gain refunds for consumers who purchased the products. According to the FTC, the enhanced performance benefits zMax claims its products provide are totally unsubstantiated, and in the same tests cited to support performance claims, motor oil treated with zMax actually produced more than twice as much bearing corrosion than motor oil by itself. They further allege that the three different zMax products - an engine additive, a fuel line additive and a transmission additive - are nothing more than tinted mineral oil.

The complaint states that since at least May of 1999, zMax has aired infomercials promoting its Power System, a $39 package of three additives to be used in the engine, fuel line and transmission of automobiles. The infomercials are quite convincing, even going as far as featuring testimonials from various consumers and race car drivers making such claims as, I was averaging about 22 miles to the gallon on the highway. I installed the zMax and so I jumped right up to about 28 miles per gallon and zMax guarantees a minimum of 10 percent gas mileage increase. Other advertising claims zMax with LinKite has the scientific, CRC L38 proof it takes your car to the Max! and Why zMax Works - Cuts carbon build-up on valve stems 66%; Lowers wear on valve stems 66%; Lowers wear on piston skirts 60%; Reduces blow-by leakage 17.7%; Increases combustion efficiency 9.25%; Lowers fuel consumption 8.5% - Results of an independent CRC L38 test.

The CRC L38 test is a standard auto industry test which measures the bearing corrosion protection properties of motor oils. According to the complaint, in early 1997 an independent testing facility performed two CRC L38 tests of the zMax products. The results showed motor oil treated with the zMax additives produced more than double the bearing corrosion as motor oil alone. According to the FTC, the defendants eliminated the bearing corrosion results, as well as all other negative results, to produce one report from the two sets of tests, using this report in its infomercials and on its website.

The FTC charge alleges that zMax did not possess and rely on reasonable substantiation for the following product claims: increases gas mileage by a minimum of 10% reduces engine wear reduces or eliminates engine wear at startup reduces engine corrosion extends engine life reduces emissions They also allege that the defendants falsely represent that the results of the CRC L38 test prove that zMax: increases gas mileage reduces engine wear extends engine life lowers fuel consumption by 8.5% lowers wear on valve stems by 66% lowers wear on piston skirts by 60% cuts carbon build-up on valve stems by 66% Finally, the FTC charges that zMax does not have substantiation for the representation that the testimonials and endorsements shown in zMax advertising are the actual and current opinions, findings, beliefs, and/or experiences of those consumers; and the typical or ordinary experience of members of the public who use the product. The lawsuit against zMax is the latest in a long line of FTC charges against auto additive manufacturers. The FTC has previously halted allegedly deceptive advertising by the marketers of Dura Lube, Motor Up, Prolong, Valvoline, Slick 50, STP and other major brands of engine treatment systems.

Which 30 Weight Oil Do I Use - What is the difference?

AMSOIL 0W-30, 5W-30 and 10W-30 synthetic motor oils are ALL 30 weight oils. The answer is that ANY one can be used regardless if your vehicle owners manual says to use, for example, a 5W-30. "W" means winter. In winter weather the 0W oil will flow like a 0W oil, and the 5W will flow like a 5W oil and a 10W will flow like a 10W oil just until the engine warms up.

In order to understand the differences one has to first understand that the numerical values given to these various weight oils are strictly empirical numbers. For example, 0W does not mean that the oil has no weight. That is one of the reasons why we say it is strictly an empirical number. In order to determine the differences between the three oils one has to look at the kinematic viscosity of each lubricant. The kinematic viscosity is essentially the amount of time, in centistokes, that it takes for a specified volume of the lubricant to flow through a fixed diameter orifice at a given temperature.

Let's compare the kinematic viscosity of the three AMSOIL lubricants:
AMSOIL 0W-30 is 57.3 cST @ 40 deg. C, & 11.3 cST @ 100 deg. C
AMSOIL 5W-30 is 59.5 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C
AMSOIL 10W-30 is 66.1 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C.

As you can see from the data above the kinematic viscosities are extremely close. Therefore, whether you use the 0W-30, 5W-30 or the 10W-30 is strictly a matter of choice. With the small differences in kinematic viscosity you would be hard-pressed to detect these differences on initial engine start-up without specialized engine test equipment.

All three oils are excellent motor oils and ANY one can be used in a vehicle which requires either a 0W-30, 5W-30 or 10W-30 oil as well as in several other engine applications including an engine which recommends a 5W- 20 oil.

AMSOIL Signature Series 0W-30 Severe Service motor oil is one of the best synthetic lubricants AMSOIL manufacturers for gasoline engine passenger vehicles and light trucks. The molecular and chemical technology used to develop this oil was derived from AMSOIL's Racing Oil. It is a 35,000 mile/1-year motor oil. This is the same oil used by numerous police vehicles and severe duty fleets nationwide. In fact, many national racing teams use the 0W-30 for the qualifying event, then they change to the AMSOIL 20W-50 Racing Oil for the race. The extra horsepower and friction reduction from the 0W-30 often assists a race driver in attaining a better starting position. In fact, we know exactly which race teams use it, but cannot disclose that information.

This leads to the next topic: many people also ask us if the 0W-30 is too thin a viscosity oil for high ambient temperature operation. The answer is absolutely not! Thicker viscosity oils are not always necessarily better since in addition to its' various engine lubrication functions, an oil must also effectively transfer heat. Only about 60% of an engines cooling is performed by the engine coolant, and only on the upper half of the engine. The remaining 40% of an engines cooling is performed mainly by the engine oil.

Although a vehicle that is recommended to use a 30 weight oil can also use a 40 weight oil, it is usually not needed. You will gain absolutely no benefit from using a thicker viscosity oil if it is not needed. The only time we recommend a 40 weight oil, such as AMSOIL's 10W-40, to a customer in a passenger car or light truck application is if the vehicle's engine is excessively worn and consumes oil at a higher than normal rate or if the vehicle is being used for very severe duty, high load, high temperature applications.

Will adding other motor oil to my engine affect my drain-intervals

Adding another brand of motor oil will reduce the amount of AMSOIL in your engine which will shorten the life of the AMSOIL motor oil. Using another motor oil will require you to change your motor oil much sooner than Amsoil recommends.

How does a synthetic oil decrease friction and improve gas mileage and performance

Synthetic oil molecules are more resistant to contaminants. They are generally smaller, and more consistent in physical size. Amsoil synthetic oil provides less stress on your engine providing superior gas mileage increase & additional horsepower. Reduced friction makes engine bearings rotate easier. This saves energy & conserves fuel. Using AMSOIL will save enough per year in fuel savings to pay for all your vehicles lubrication needs.
