Tried lucas in my steer axle hubs once,.. It foamed up a lot.. even after a couple flushes just to be sure .. and it looked like crap. - I Had to go back to Mobil.

That sucks too, because I had gotten 4 gallons of it. - I ended up lighting camp fires with it.

I have more than a million on my drive line, tranny, rears, etc.

I have always used Mobil Synthetic on the gear boxes and tranny.

I am thinking I am ready for a new clutch yet? it has never been changed either .. -- but then again, the indicator says it is only worn by 45%.

I don't go 70+ mph, I go 55-60 mph the whole trucks life and keep boost below 20. - A decent oil and taking care how you drive makes the most difference I think.
