Hey Cruiser Gods,

I don't mean to beat a dead horse, but I have an easy question. I'm doing the transmission/transfer case return line this weekend and I want to know what type of Oil everybody is running. I planned just running 90wt. but if there is anything that would be better I would do that. Just so you know I looked at the sticky with all the info, but did not quite understand it. I have an 84 fj60 220,000 miles, Stock. I'm trying to catch up some jobs that have been neglected so I can do some trail rides this summer. Thanks a Million.

80 w 90

But you will be fine with 90 wt


The reason to go to a thinner oil (lower number) is due to temp. If it is freaking cold out, you will want a thinner oil.

Everyone seems to use 80W-90 GL-5. Buy it at any auto parts place. If I feel rich I may experiment with Redline MT-90, a 75W-90 GL-4 synthetic. But it really does seem to work fine with the everyday stuff.
