i use moble one sythetic in crank case and redline in tranny and rearend.

normal coolant and always highest grade fuel.

I had learned thru the years, that its not a good idea to start putting synthetic into an engine that has over 50k on it. The seals may start leaking because the syn. will clean things up, and is thinner, and will find its way out.

OOOPPSSS!!! 2 years ago I had a brain fart, and replaced the Dextron 3 in my Power Steering with Amsoil syn. 1 month later, the rack blew the left end seal. Oil everywhere !!!

It happened on the way to the "Hot Import Nights" car show at the L.A. Covention center, Sat. night on Labor Day weekend. Well, I said f*** it, and went on in and had a great time, as I'd just have to deal with my problem on Sunday. (you should definately attend one of the shows near you)

So.....be cautious with swapping to syn. on old systems and seals.

I've used synthetic everything in the 81 FJ60 Landcruiser and 89 7MGTE I own and never had a problem. And yes Redline in tranny and rearend. 60/40 in the radiator Prestone. And ALWAYS the best fuel, its worth the 15 cents more or whatever.

In the Landcruiser? Since the factory oil was changed out, its now at 200K with no leaks. It had one from the pan gasket and the side valve cover but c'mon now, its older than I am. I replaced the factory gaskets at about 190000. No more leaks. The most convincing argument should be that the car is 25 years old with 200K and doesn't burn a drop of oil, the block nor head has ever been opened. Everything is factory pistons, rings and cylinder sleves, etc.

In the supra? I got it at 130K and immediately put synth in it. It had a leak prior so i don't know about synth leaking. never heard that before anyways.

I don't think synth contributes to leaks. In my professional opinion (lol) if a car is leaking or burning oil, its a lack of maintenance issue. A gasket that wasn't installed and torqued down right or not sealed with rtv in a sparing yet adequate way is usually the cause of a leak. Cork gaskets also need to be retightened a few times after being replaced. Alot of people over torque and crack them too. 9ft lbs is usually what is recommended, at least most toyota ones.
