Are AMSOIL motor oils “all-season” oils?

Answer: Yes. Because AMSOIL motor oils are formulated with premium synthetic base oils, they have superior high and low-temperature performance. Synthetic oils resist thinning out at high temperatures to maintain critical protection in extreme heat. They also minimize sludge and deposit formation in high-temperature operation. AMSOIL synthetic motor oils resist thickening in cold temperatures to provide rapid cold starts and improved low-temperature operation compared to conventional oils.


Extreme cold can cause conventional motor oil, transmission fluid and gear lubes to thicken, starving moving parts of necessary lubrication. In many cases, thick motor oil prevents vehicles from starting. Cold, thick transmission fluid results in delayed or sluggish shifts and inadequate protection for bearings in the axle housing are splash-lubricated, conventional gear lubes that are too thick at cold temperatures can starve internal components of essential lubrication, which causes excessive wear and premature failure. Conventional petroleum lubricants thicken because they often contain paraffin's (wax). While modern refining techniques remove most of the wax from petroleum oil, some wax-like molecules remain. These wax-like molecules are soluble at ambient temperatures above freezing, but crystallize into honeycomb-like structure at lower temperatures and cause fluid circulation problems. At start-up, this can leave working parts unprotected while lubricants warm to a temperature that allows it to flow.

AMSOIL Synthetic Lubricants do not contain paraffin's. They provide outstanding low-temperature fluidity for fast, dependable winter starts, quick responsive shifts and immediate start-up protection.
