thats kinda what ive been thinking... unless your gaskets are already shot, some of the newer sythentics might be beneficial.. idfk. Ideally, at the next oil and filter change i would like to change diff,tc, and transmission fluid, aswell as plugs and maybe wires.
I would like to switch to all synthetic fluids, but we'll see about that as the time comes. Ill get plugs from toyota, and have to research plug wires. I want her to run her best of course
