The First In Synthetics
36% EASIER AND FASTER COLD STARTS
When the temperature drops, motor oils thicken and move slower, causing parts of your engine to remain unprotected for a short period of time. AMSOIL is more fluid at cold temperatures than the tested conventional oil, giving you 36% easier and faster cold starts*. This means that it can reach vital components faster, providing more immediate engine protection and reduced wear.

In order to keep on pace with the increasingly strict fuel economy standards, vehicle manufacturers are designing engines differently, causing them to run hotter than ever before. The average operating temperature is up to 235°F, and even higher under heavy loads. This heat can quickly break down the oil and cause oxidation, sludge and deposits.
Recent tests show AMSOIL keeps engines 81% cleaner* (5 times cleaner) than conventional oil by better resisting the formation of deposits.
