Sensible Answers to Common Questions
About Synthetic Motor Oils

Synthetic motor oils were introduced in 1972 by AMSOIL INC. and were proven to outperform conventional petroleum motor oils. Recognizing this, all major motor oil manufacturers have begun marketing their own lines of synthetics. Use of synthetics has sharply risen as motorists respond to concerns about engine life, fuel efficiency and repair costs. With the rising cost of automobiles, consumers simply want to protect their investment, and synthetics are the best choice.

Although most of the mystery and doubt about synthetic lubricants has vanished, questions remain. The cure is knowledge. When customers know the facts, they recognize the superiority of synthetic lubricants, just as original equipment manufacturers like General Motors and others have. AMSOIL remains the industry leader. Customers looking for the best protection, performance and value in synthetic motor oils look to AMSOIL.

Question # I

"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.

Question # 2

"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 it's product line. AMSOIL has set the pace in development of premium synthetic lubricants of all types.

Question # 3

" I just bought a new car, boat and motorcycle, and I'd like to try AMSOIL. Could using AMSOIL products void my new vehicle warranties?"

Users of AMSOIL Synthetic lubricants need not fear altering their warranty coverage. The contention that using an aftermarket product like AMSOIL Synthetic Lubricants could void new vehicle warranties is simply not true.

Major auto manufactures and regulatory agencies have determined that warranties must cover all equipment failures they would normally cover that are not caused by the aftermarket product. Consequently, an AMSOIL users new vehicle warranty still covers all failures resulting from defective original equipment or faulty workmanship by the manufacturer.

The second element of your protection is the AMSOIL limited Warranty (use AMSOIL Synthetic lubricants as recommended in mechanically sound equipment, and the warranty covers lubricant related failures). Since AMSOIL motor oils have never once been deemed the cause of an engines failure, however, this is merely added protection.

Question #4

"I was always told to change my oil at 3,000 miles if I wanted to keep my car running well. How is it possible to drive 25,000 miles without an oil change? using AMSOIL, and will extending my oil change interval void my warranty?"

AMSOIL synthetic Motor Oil is guaranteed to run for 25,000 miles or one year in a mechanically sound engine, providing of course, the oil is kept free of contaminants by changing the oil filter according to the manufactures recommendation or when using an AMSOIL oil filter, changing the filter at six months or 12,500 miles which ever comes first. AMSOIL coined the phrase "extended drain interval" and it's been validated by over 25 years of industry testing and by tens of thousands of motorists and multi millions of over the road miles. Based on their results, 25,000 miles is a conservative estimate.

AMSOIL Synthetic Motor Oil performs so well for so long because it doesn't break down in intense heat like conventional oils do. It doesn't form performance-robbing deposits and it doesn't volatize (evaporate), which can adversely affect lubricant performance by altering viscosity and increasing oil consumption. Finally, AMSOIL's Ultra-Premium additive package, a key element in a lubricants ability to function, holds up under engine stresses, remaining serviceable for the full 25,000 miles.

Note also that extending drain intervals, like using AMSOIL Synthetic Motor Oil in general does not affect new car warranties. In fact, according to a General Motors

representative, "Warranty applicability is contingent upon the cause of the failure and generally covers defects in material and workmanship only" In other words, the only situation in which warranty coverage would change is the case of lubricant related failure (in which case the AMSOIL Limited Warranty protects the consumer).

Question # 5

"AMSOIL costs more than my regular oil does. How can I justify paying this higher cost?"

AMSOIL Synthetic Motor oil is more expensive off the shelf than most petroleum oils. But comparing AMSOIL and other motor oils is like comparing apples and oranges; AMSOIL's performance so far exceeds that of conventional motor oil, it's really a different class of product. AMSOIL is a premium product that rightfully commands a premium price.

Like anything of real value, however, the true consumer cost doesn't end with the off the shelf price. AMSOIL Motor Oil is extremely cost effective compared to conventional 3,000 mile drain interval oils in savings realized in fuel economy, reduced repairs, fewer oil changes, reduced downtime, reduced maintenance and extended engine life.

Question # 6

" I bought a new car a year ago, and I've been running petroleum motor oil in it ever since. Could switching to AMSOIL now cause mechanical problems?"

Switching from petroleum motor oil to AMSOIL (or even mixing the two, if the need arises) is perfectly safe. AMSOIL is 100 percent compatible with petroleum oils. Mixing AMSOIL and petroleum is not recommended (having petroleum motor oil mixed in detracts from the superior performance of AMSOIL), but there is no danger in doing so. Those who have been using petroleum motor oil in their mechanically sound vehicles can switch to AMSOIL safely. Petroleum motor oil and AMSOIL Synthetic Motor Oil are only incomparable in the way they perform, not incompatible.

Question #7

" I've been using a petroleum motor oil since I started driving, that was a long time ago. Why should I switch to AMSOIL when I haven't had any problems with what I am using?"

Chances are you are not driving the same car you were when you started driving. Automotive technology has changed a great deal, even in the past few years. Today's cars have more power, use less gas and have smaller engines than ever before. High performance mixed with small engines means high stresses and increased demands on motor oil.

How expanding technology and modern engine needs affect motor oil is a primary concern of AMSOIL engineers. High-tech engines need high-tech oils like AMSOIL Synthetic Motor Oil-designed, not refined. AMSOIL motor Oil's base stock is composed of uniform molecules chosen for their lubricating characteristics. Petroleum oils are a hodgepodge of molecules; some lubricate, others detract from the ability to lubricate. The bottom line? AMSOIL's engineers can design their motor oil to meet the needs of you and your motor vehicle, petroleum refiners can't.

Using an oil designed for today's needs can make a world of difference for you and your automobile by providing lower repair costs, the convenience of fewer oil changes, easer starts in cold weather, better gas mileage and longer engine life. You can also expect better engine performance. These factors and the overall savings realized by using AMSOIL Synthetic Motor Oil make switching to AMSOIL the smart and easy choice!

Question # 8

"Can AMSOIL Motor Oils be used in any engine?"

Certainly, AMSOIL Motor Oils may be used in any mechanically sound gasoline or diesel engine. Basically that means they are excellent for use in any vehicles engine. (Not rated for aircraft or train diesel applications)

Question # 9

"Are AMSOIL Motor Oils all-season oils?"

Synthetic oils are made to protect and perform better than petroleum oils at high and low temperature extremes. That's why every jet aircraft engine in the world is lubricated with synthetic oil. AMSOIL Motor Oils have extremely low pour points and flow readily at extreme 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 high performance engines.

Question # 10

" Will AMSOIL Motor oils increase gas mileage?"

Tighter government regulations and increases in engine manufacturers' demands are calling for more fuel efficient lubricants. AMSOIL Motor Oil's reduce friction and drag far 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 to expect.

Question # 11

" 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.

Question # 12

"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 insure that the engine is clean and free of any accumulated contaminants, which might have an effect of the service life Of AMSOIL Motor Oils. In all cases, it is good judgment to install a new AMSOIL Full Flow Oil Filter every time you change oil.

Question # 13

"Should oil additives or after market products be added to AMSOIL Motor Oil's?"

NO, they are not necessary, and may be detrimental! AMSOIL Motor oils are properly formulated under the strictest Quality Control procedures to provide unequalled lubrication performance.
