So the cost is not so high when you put a lot of miles on your car. But why should I use AMSOIL synthetic motor oils if I don't put a lot of miles on my car each year?

There are many:

Peace of Mind- - All season AMSOIL synthetic motor oils help cars start and run dependably in the temperature extremes of northern winters and deep-south summers.

Long-term, AMSOIL synthetic motor oil's superior cold temperature fluidity, high temperature stability and oxidation stability keep cars running dependably longer, too, by reducing the wear incurred during cold starts and under-protected high temperature operations and by keeping engines virtually free of oxidation products such as sludge and acids, all of which are harmful to the engine.

Not only do AMSOIL synthetic motor oils enhance engine life, the oil itself also provides dependable long term service - perfect for those who may not service their car regularly.

Saves Money - - Because AMSOIL synthetic lubricants are molecularly smoother than conventional oils, they create less friction in the engine. With less friction in the engine, less engine power (which comes from fuel) is wasted overcoming friction. That means better fuel economy - more miles to the gallon.

AMSOIL synthetic motor oils extend the period of "like-new" performance. For those who keep their cars as long as they run dependably, the performance gain sometimes equals years of extra service. For those who trade their cars on a schedule, the superior engine cleanliness and low wear may translate into higher trade-in value.

Performance - - By creating less friction in the engine than conventional oils do, AMSOIL synthetic motor oils help engines deliver more horsepower, which increases top-end speed and responsiveness throughout the speed range. Additionally, as petroleum oil ages, new means of increasing friction develop. For example, oil volatility and oil oxidation both thicken oil which increases its internal friction and hampers performance. Oxidation also changes oil chemically, forming sludge, varnish and acids. Sludge and varnish impede free component movement while acids degrade component tolerances and encourages sloppy component performance.

AMSOIL synthetic motor oil's thermal and oxidative stability make the oils highly resistant to volatility and oxidation, so they maintain their high-performance viscosities - and "like new" performance - long term

Solves Problems - - Synthetic lubricants often actually help hot-running engines and other equipment run closer to their optimal temperature range than conventional lubes do and that can spell the difference between safe operations and failure in high stress conditions such as racing. In fact, AMSOIL synthetic motor oils have been shown to reduce engine temperatures as much as 50 deg. F.

Friction-producing oils are heat-producing oils, which means conventional oils are bigger heat-producers than AMSOIL synthetic oils are. Additionally, conventional oils are less efficient in removing heat from component surfaces than their AMSOIL counterparts are, due to differences in the way the oils flow. Conventional oils flow in layers (laminar flow) along component surfaces. Heat isn't exchanged readily between layers. Synthetic oils flow in a turbulent pattern which moves heat readily into the oil stream and away from component surfaces.

Convenience - AMSOIL synthetic lubricants are formulated specifically for long life. For example, the motor oils can be used for 25,000-mile or one-year drain intervals in most applications.

The synthetic basestocks used in AMSOIL lubes are highly resistant to thermal and oxidative damage. Thermal and oxidative damage are two of the major processes that spell the end of conventional lubes.

Other major processes which require that a lube be replaced are changes in or depletion of the additive package. For example, some additives used to increase viscosity during high temperature operations actually lose their ability to do so through the shearing action normal to an operating engine. On the other hand, additives used for keeping acids in check are used up over time.

Conventional lubricants are formulated for drain intervals up to 7500 miles in length. Basestock degradation and additive changes or depletion both occur shortly after than point. When long-life additives are available, conventional oil manufacturers would be wasting their money to put those higher quality, more expensive additives into conventional basestocks.

AMSOIL, on the other hand, uses the high-quality long-life additives that allow the synthetic basestocks to realize its long life potential.
