I was using the Valvoline Durablend, the 1/2 syn and 1/2 regular oil, I was told it would be ok to change over to the fully syn.
Brake and power fluid aren't the original. I just can't remember when they were changed last. I have had so many repairs on the car, it's hard to keep track of when it was changed last.
Maybe I should change the question. What intervals should those 2 fluids be changed (milage and years)? And what's the best product out there that I can use?
