Burning Oil

[5LTREATR]

Hey guys so when my truck hit 65000kms it started burning oil about 2 - 4 Quarts per 10000kms oil change the dealership says that it is normal do you guys have any thoughts? there is definatly no leaks and the truck runs great is this something I should worry about?

While acceptable within GMs service limit (1L per 1000kms) It is not normal to go from burning no oil to 2+ litres. Keep an eye on it, hve you rerouted the PCV or switched oil brands or anything recently?

I was using just GM 15w40 when it started so I thought i would switch to Mobile 1 Synthetic 5w40 and the oil burning continued

id stick with One brand and maintain records for a few month and take them back to the dealer to see what they say then. Date, mileage, amount of oil added or if changed.

Agreed. If its all of a sudden then theres a problem. Any oil in the cooling system?

Is your oil pressure higher than usual?

Mine used a quart to two quarts before it was time to change the oil when it was brand new when ran hard pulling equipment. Did the pcv re-route and it hasn't burned another drop since then. Try doing that first and if it still keeps using oil than I'd say you got a problem.

my oil pressure is normal I had the truck p on the hoist and it doesn't have even the smallest leak whatsoever i was thinking that maybe because i don't run my truck very hard that the rings didn't set properly so have some blow by maybe.
