Going to change the oil in the front and rear diff's of my 2001 LC. Last time I used mobile 1 full synthetic 75/90 in the front, center, and rear as it was a readily available product on store shelves. FSM lists sae 90 gl5 in front and rear and 75/90 in the center. I've also heard that you shouldn't use full synthetic but that may be splitting hairs. Considering a sae90 nonsynthetic product from ravenol (about $16/quart) and wanted to get thoughts from the community.
I used ravenol on the diffs in my daughter's gx last year and was really happy with the product, so I'm leaning towards the product for my hundy. Input would be great. Thanks.
