GM 8.1 496 gas engine "normal" oil loss/use?
Just returned from our first looong trip with this truck and camper package and noticed (what I think) excessive oil use. The does not leak but in 3800 miles needed 1 1/2 qts., that seems like a lot t...

Sounds about right (all) , ... but I knew that going in.
Frequent changer of oil, doesn't seem to matter Dino or
Synth. . No obvious leaks. Expensive vehicles to own and
operate, never met a gas station it didn't love. I use to
worry about mileage and oil drinking... not so much anymore,
that worry didn't change anything. Now I put gas in when it
needs it, and change/add oil when it needs it. The 8.1L Vortec
with the Allison and 4.10 rear end is built to haul heavy
loads... I appreciate my truck.
Good luck

ps, I get nowhere near the mpg I see many state (underload or
free-wheeling). Good empty = 13-15mpg, hauling 5ver = 7-9 mpg.
..but haven't checked in a few years.
