New LLY, changed oil and filter at 850 miles, and plan on changing this weekend at around 3,100. Had the truck about a month now, checked oil tonight, it is in the middle of the stick!! When I changed it at 850, I made sure it was full. Is this something to worry about? Hopefully just part of break in?

Engines require a period of time to BREAK IN so that moving parts are properly seated. Therefore, oil economy should not be tested until the vehicle has accumulated at least 6400 km (4000 mi). An exception would be allowed only if an engine is reported to be using more than 0.946 liter (1 qt) in 1600 km (1000 mi).


This is right out of the GM service information mainframe reference GM bull#01-06-01-011A

this is the same issue for the turbo i replaced. check your oil and you couls losten the turbo charge air cooler pipe (blue rubber hose or black rubber hose )turbo out let intake inlet losten the clamp pull off and check if any oil is passing into it.

Well, I'm gonna change it tomarrow and really keep an eye on it.

I have 2,200 miles on mine and it hasn't used any oil, Still full.


I thought it woild use a little, but I am supprised to see it hasn't yet.
