Ok, you young fellows seem to know what you are talking about. So we will give it a try. The FJ is my wifes ride but I have to take care of it. I plan to change the rear diff with Redline 75w90 at 5k but the front and transfer at 15k with same. I still plan to use Castrol 5w30 in the engine for at least two more oil changes till I start using Redline 5w30. I can't help it I'm old school, any reason I shouldn't? Myself I have a Dodge Ram 2500 4x4 six speed manual with a Cummins and run Rotella in the engine and Redline in all running gear with no problems. We live pretty far out in the sticks and my wife got the good out of two Rav4's and wanted to buy a third and I said why don't you try a FJ, and she just loves it. It came with the off road package: Nitto Dune Grapplers 305-70X16's on TRD rims with a lift, not sure how much, Borla duel exaust and air filter, front brush guard and PIAA lights plus othe stuff. Will post pic and profile when I get time. Thanks for your insite,help and advise. Oh ya, I kinda like the dam thing myself.
