Greetings, My 06' is coming up on 112,000-miles and running strong. I am planning on changing the transaxle fluid within the next two weeks. After reading almost every post relating to the transaxle fluid I have come up with 3-opinions: 1. Use the Toyota ATF-WS 2. Use Redline D6 3. Use Redline D4 I understand that Redline is pushing the D4 for the viscosity reasons. However has anyone had negative results running the D6? Thanks, Victor
I have yet to see a UOA (used oil analysis) for Redline D4 or D6. I have seen several UOA for WS including a couple of my own. UOA shows that WS is good for at least 30k miles; that is the interval I am using from now on. Redline may be better or worse, but without running the UOA your guess is as good as anyone else.
This analysis of one data point (one car, three changes at 60K intervals) shows Toyota WS may be good for 60K miles. Good luck!
