Happy to report mileage has gone from 18 to 19.9 mpg after Royal Purpling (synthetic oil/gear lube) differentials. Tranny next (soon I hope).

Good to hear. Royal Purple is supposed to be great product. Never used it I got a Mobil 1 thing

Great to hear it! ;Do; After going 100% Mobil-1 in the Dragon it averaged a consistent 2 MPG increase. I started changing over as each service item came due from new, although I did the tranny a bit early out of impatience. When I got the IronMan I pretty much did everything across the board to 100% Mobil-1 since it had 99,500 miles when purchased. Now I'm at 106,000 and just got 21MPG highway on a recent road trip. Darn thing is peppier and more efficient than the bought-new Dragon! Oh well, it's an Isuzu... they just get better with age! ;pg;
