Questions and Answers

Below are answers to some common questions people have about AMSOIL products and Northwestern Lubrications.

AMSOIL oil products AMSOIL Products Northwestern Lubricants and AMSOIL Business

Does AMSOIL have a zinc additive?
No. AMSOIL products contain MAX-DOSE of zinc and phosphorus for greater wear protection in engines with flat tappets and high horsepower. Z-ROD, oils contain 1440 ppm zinc. DOMINATOR, racing oils contain 1575 ppm zinc. AMO-10w40& ARO-20w50 contain 1379 ppm zinc. HDD-5w30, Heavy Duty diesel oil contains 1379 ppm zinc. AME-15w40, Diesel-Marine oil contains 1377 ppm zinc. The rule of thumb is 1600 ppm of zinc. Anything over that causes oil to foam. Therefore, your protection is gone.

Can I use AMSOIL AFF 0W-40 in my new 4-stroke snowmobile?
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...

Can AMSOIL Motor Oils be recycled?
A. Regarding used synthetic oils, they 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.

What are AMSOIL Synthetic Motor Oils?
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.

What are AMSOIL Synthetic Blend Motor Oils?
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.

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.

Will AMSOIL Motor Oils void the warranty of a new vehicle?
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.)

Are AMSOIL Motor Oils All-Season Oils?
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!

Will using AMSOIL Motor Oils increase gas mileage?
Tighter government regulations and increases in engine manufacturers' demands are calling for more fuel efficient lubricants. AMSOIL Motor Oils reduce friction and drag better than petroleum oils, resulting in significant fuel economy increases. In a recent 1.2 million mile demonstration, AMSOIL Lubricants showed a 4.5% increase in gas mileage. Other tests have shown increases of as much as 15% under certain weather and driving conditions. Yet, because every vehicle is different, as are driving habits and conditions, it is difficult to accurately project an exact increase.

Are AMSOIL Synthetic Motor Oils and petroleum motor oils compatible?
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.

Why are AMSOIL Motor Oils capable of extended drain intervals?
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.

Will AMSOIL Motor Oils decrease oil consumption?
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.

Is there a recommended procedure for changing to AMSOIL Motor Oils?
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.

Should Oil Additives or After Market Products be added to AMSOIL Motor Oils?
No, they are not necessary! AMSOIL Motor Oils are properly formulated under the strictest Quality Control procedure to provide superior lubrication performance.

I heard that new cars require a break in period with petroleum before you switch them to synthetic. How long should this break in period be?
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.

I am considering replacing the petroleum oil with AMSOIL synthetic oil in an engine that has 50,000 miles on it. I have heard that synthetics might clean the engine and cause plugging of the oil filter and passageways. Is this true?
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.

Is it true that installing AMSOIL or other synthetic oils will cause my engine to leak oil?
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.

How long have AMSOIL lubricants been on the market?
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.

Can I use other brands of oil filters with AMSOIL?
Yes, but you would have to change them more frequently.

How can I save money and maintenance by using AMSOIL?
The intervals for changing oil and filters are extended, therefore, saving on maintenance costs. The oils clean and suspend dirt and the filters have the ability to remove and contain dirt longer.

Why can't you use regular car oil in motorcycles?
Car oils contain friction modifiers. Most motorcycles have wet clutches and car oils will cause them to slip.

How do you pull oil samples?
There are a couple of different ways to pull oil samples. You can pull the drain plug and about half way through the drain, take a sample. Then, there is the pump method. You attach a small plastic hose to a hand pump and pump a couple ounces into a catch bottle. Another way is when you are changing filters. After the filter is removed, some oil runs out and you can catch a few ounces in a sample bottle.

Can I buy products without having to sign up with AMSOIL?
Yes, products can be purchased without having to sign up with AMSOIL. You can purchase products online through Northwestern Lubricants. You can join AMSOIL's preferred customer program without the responsibilities of becoming a dealer.
