A couple of differences are the following: Motor oil is designed to deal with the products of combustion, whereas 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.
Can you use automatic transmission fluid for motor oil?
In most cases, adding ATF to motor oil reduces cleaning power. Instead, ATFs have elevated levels of friction modifiers and other additives that help protect gears and clutches. Second, ATF can disrupt the engine oil formulation and reduce its effectiveness.
What happens if you put engine oil in ATF?
Using pure motor oil would certainly result in transmission failure very quickly as the clutches and bands would slip and wear out (and also cause extreme amounts of heat in the process, coking up the oil and likely damaging many other components too) but a small amount won’t throw off the friction modifier content of …
What can I use instead of automatic transmission fluid?
Any light weight quality engine oil or hydraulic fluid will work 5 to 10 single weight or multi weigh 5W-30, 10w 30.
What can I use instead of ATF?
Yes, you can use motor oil instead of automatic transmission fluid.
Is transmission fluid thicker than engine oil?
Gear oil is also thicker than ATF because it serves mainly to lubricate the gearbox, transfer cases, and differentials. Incorrectly using ATF in a manual transmission or gear oil in an automatic transmission can severely increase the wear and tear.
