AMSOIL offers three categories of premium quality synthetic motor oils formulated for extended drains.
AMSOIL synthetic oils resist oxidation and prevent engine sludge. AMSOIL engines are clean even after 150,000 to 200,000 miles and even more. Stop sludge and varnish from killing your engine with AMSOIL Synthetic Oils! AMSOIL Synthetic Motor Oil is highly resistant to vaporization, losing only six percent of its weight in high temperature service. AMSOIL resists oil breakdown from heat, blowby chemicals and oxygen longer than do conventional oils. AMSOIL resists forming varnish deposits and sludge. It doesn't thicken like petroleum oils, but continues to cool and lubricate, providing peak engine performance, power and protection. In addition, the advanced heat transfer capabilities and high lubricity of AMSOIL keeps engines, transmissions and gear boxes running in their optimal temperature range, for top performance and long life.

Many other weights are available at our online store. (These are just some examples).
