Well, not really, but Amsoil states that the transmission fluid is good for 500,000 miles. They also state that their oil is good for 25,000 miles between changes. There are some additives that you have to pour in every now and then, but that's about it. I didn't do the oil because I just don't trust a 25,000 mile oil yet.

Anyway, all of that is to say that when they where changing the fluids out they said that the old stuff was in fantastic shape and could have gone another 70,000 miles (the VX just turned 70k after Moab). To my knowledge those fluids where never changed by the previous owner so it seems like Isuzu put some good stuff in there to begin with.

I'm completely in agreementalness with Mark...I have run nothing but Amsoil in every orfice since about 20k, & I think my oil usage during the Moab excursion (1 qt. in almost 2500 mi.) speaks for itself.

It's more expen$ive to use @ regular change intervals, & there's no WAY I'd go 25k on an oil change...but there's nothing too good for Suzy.

IMO, it's the "good stuff".
