My 89 cabby has over 400 k on it I use some of this stuff every couple of months, a bit in the tank, a bit in the crankcase. Works wonders on the lifter tick helps tired hydraulic lifters, nearly eliminates it.

MMO is the cat's ass for fixing collapsed hydraulic lifters in the Vanagon engines. Throw a few ounces in, drive it for a 100 km or so, then do an oil change and it seems to clean the crap out and get the lifters quiet again.
