Synthetic instead of TCL-1 (quadratrac)

[AllJackedUp]

I recently bought a '77 J10 with quadratrac. I've never had a qt before so I know nothing about them. I'm currently replacing brake pad/shoes to get it to stop. I've got the engine running but I haven't replaced the qt fluid yet.

I was wondering if anyone has run a synthetic 30 wt. oil, like Royal Purple, in their qt? or should I just stick with regular non-detergent 30 wt & limited slip additive?

I'll post pics later today once I put the 17" toyota black wheels on it. I hope they don't rub! :drivin:


Thanks,

Running syn motor oil isn't going to cancel out the need for the friction modifier so what's the point of going syn?

Some synthetics have friction modifiers already mixed in...

I know Mobil 1 gear lube does, not sure about the specific requirements of the QT though.

Try it out, worst you can do is destroy the diff in there:rolleyes:

I would stick with TCL-1 or the factory AT fluid. You definitely can't just use 30 wt oil. I think someone had posted a formula for mixing your own QT fluid. I've never done it. You might try a search and see if you can find the thread.

Thanks fellas. I'll probably just pick up some TCL-1 from BJs. I can't wait to drive it for the first time!!
