Anyone else have a 2007 -2015 GM / Chevy with the Active Fuel Management (AFM) that uses oil? I have read several threads on truck boards about this that the AFM is what is causing my truck to use oil. My wife's 2007 Tahoe is starting to use oil as well now, and she has the AFM 5.3L also.

A few of these threads are also touting this Range Technology AFM Disabler that keeps your truck in V8 mode all the time. Keeping the motor in V8 mode is supposed to reduce or stop the oil burn caused by AFM. http://www.rangetechnology.com/pages/v8

Also, do any of the Chevy / GM V8s come with out the AFM anymore? Can't seem to find one on the used car sites with out it.

Mine is using oil too... I took it to GM dealer they changed the oil and said to come back at 1000 miles, should be tomorrow...

He said there were 3 options to fix it, some type of sensor (prob exactly what you are talking about), New Top end, or brand new Motor...

Since it's still in warranty I don't care as long as they fix it.

Will know more after tomorrow.

My '07 has the same issue.

Mike, What year is yours?

I have heard before that this is very common in the 07 and up

My mechanic says the same thing. Several of his GM customers have issues with oil usage.
But his 06 Chevy with the 5.3L is fine though. No AFM.

AFM SUCKS! I have an 07 Silverado with the 5.3L. It generally burns 1 qt every 3k miles. I have heard that you can disable the system and if your out of factory warranty they can't cancel your warranty.

RedHead, stay on em and don't let up. Hopefully they will make it right since you're still under factory warranty.

Have an 07 Tahoe , burns at least a quart between changes. Only has about 70k on it. I have been thinking about trading it in on an expedition el.

geez, 1 quart every 3k. That's high... I wonder if it's caused by heat buildup around the non firing cylinders when AFM kicks in? That would be my assumption anyway.

I have 4 friends that have all had the same issue.

My 2006 with the 5.3 L consumed a quart of oil every 3000 miles. That motor did not have fuel management so I wonder if there something else causing it?

FWIW...i know of several vehicles that use a quart every 3000 miles. I have an older toyota that actually states that kind of oil usuage on the service manual. Its the ones that use this 0w and 5w oil that scare me.

2001 5.3 yukon had started using a quart every few thousand miles, as well. 168k miles on it when i sold it and rarely had to add any between changes until around 145-150k.

Mine is a 2011 Silverado

Took it by there today.... no oil usage first 977 miles?

get to go back after the next 1000...
