i have 60K miles on my 5at coupe and im going to drain all fluids and replace them all with synthetic..what is everyone using as far as transmission fluid, differential lubricants, and just oil? Mobile 1 is known for their synthetic motor oil..what about the other fluids and lubricants?

 

For the AT stick with the OEM fluid.
It's synth & designed for the tranny.

If the car is under warranty, using different AT fluid can void warranty

 

With 60k, I wouldn't go synthetic. I think it's better to go synthetic when the car is still pretty new. Correct me if I'm wrong.

 

New engine = new parts = needs to be worn down.... Syn is too thin to do a good job of wearing down parts

Old engine = worn parts = bigger oil clearances = needs thicker oil.. syn is too thin

but no 60k is fine to go syn.. 60k is nothing.. that motor still has another 140k to go lol
