I'm going through a season of maintenance on my 2004 4runner V6, SR5. I have 165k on the odometer, never changed my rear differential. Feel like I need to
.
I've read that 75W 90 is a popular weight for daily drivers. I don't do any towing as a practice, but may do so once every few years. I live in the Southeast and we don't get extreme cold temps down here.
Looking at Mobil One 75W 90 synthetic but a few posters in a 4runner forum warn against the move to synthetic. Many other haven't had an issue.
Need advice on 2 items please.
1. Are there any genuine risks to going synthetic? If so - what are they?
2. Is my mileage too high to change the differential?
thanks guys!!
Jon
