Difference Between Motor Oil and Transmission Fluid
I work at an auto parts store and customers ask the difference between motor oil and transmission fluid. What would your explanation be? Quick and simple - to the point.

Answer:
Motor oil is for your vehicle's engine. Transmission fluid is used by your steering system to keep its parts moving smoothly. A couple of differences are the following: 1) an engine is designed to deal with the products of combustion, whereas an automatic transmission fluid (ATF) does not see contaminants from fuel burning. An ATF is basically a closed system and the lubricant must last for a long period of time. An engine oil must be drained to remove contaminants after a relatively short time/or mileage compared to an ATF. Similar additive component types are used, but at different levels and different chemistries. In an ATF, clutch friction is a very important consideration.
is it just me or did someone miss the pot second sentence of the answe? while some PS systems use ATF I think someone cut and pasted from the wrong source ha ha.... go mobil
