Preventing Oil Consumption

Preventing Oil Consumption

Postby KT71 [OP] » Oct 26 2012, 3:37am

Well I've been reading a lot about the oil consumption problems for these newer 5.3 engines. I just got a 2011 Silverado with about 8k miles on it and I figured I would start now on trying to prevent oil consumption for mine. I know many people seem to think that AFM could be the culprit in this problem but I would really prefer not to get it turned off until my warranty expires. So what are some other things I can do early on in the life of my engine to help?

I really don't know of any other way to prevent it then a tuner. Mine burns a little but in 5k miles but not enough to worry about. My best recommendation would be to keep a close eye on it and if you start to burn an excessive amount go to the dealer.

This is more of a problem with older designs of the AFM. The current interation doesn't really have those problems. I've got ~22k on my 2011 and haven't burned ANY marked amount of oil. The older AFM had noticable problems with blow-by oil consumption and generally any engine is going to consume some, moreso with higher miles.
