What is 75w90 Synthetic Oil?

75w90 synthetic oil is a type of lubricant specifically formulated for use in automotive gear systems. The designation "75w90" refers to the oil's viscosity characteristics, with "75w" indicating its performance in cold temperatures and "90" representing its viscosity at high temperatures. This dual-grade feature ensures that the oil remains fluid enough to provide effective lubrication in cold conditions while maintaining sufficient thickness to protect gears at higher operating temperatures.

Synthetic oils like 75w90 are produced through a chemical process that involves the synthesis of base oils and additives. This process allows for a greater degree of control over the oil's properties, resulting in a product that offers superior performance compared to conventional oils. The consistent molecular structure of synthetic oils provides enhanced stability and protection against thermal breakdown, oxidation, and sludge formation.
