I'm trying to get everything switched over to synthetic and the only thing left is the tranny.
Engine, tcase, differentials, and power steering all synthetic. Actually my brake fluid says synthetic on the bottle, but from what I understand all brake fluid is basically synthetic.
I've just been using Valvoline's full synthetic engine oil. Intially I was using Valvoline's Durablend because I thought it was full synthetic, but it's not.
