Motor Oil

Question Answer
main functionlubricate moving parts
secondary functionscleans, stops corrosion, cools engine
important property and whyviscosity (must be high enough to maintain lubricating film but low enough to flow around and keep all parts well coated)
SAE stands forSociety of Automatic Engines
higher SAE grade number (first number) meanshigh viscosity
