Afm And Oil Consumption

pm26 · January 31, 2011

GM might consider renaming the AFM system from "active fuel management" to "active oil burner" or "AOB".

I think my 6.2L is using some oil too. My oil change guy mentioned it to me yesterday. I think the damage is already done because my truck stalls and fails to start sometimes. My last GM vehicle.

Is that an AFM motor too? I believe that some 6.2s had AFM and I know that some new ones (e.g. in Escalade) have it too.

AFM was not an option back in 2006. They probably added that b.s to the new models.

uh oh. Got the "Add engine oil" message today for the first time... I'm between oil changes, I have gone 5000kms since last oil change, and I usually change it at 6000kms (4000mi)

Heeeeeere we go.... think I'm just gonna drive it straight to the dealer and start one of these "oil consumption tests" I've been reading about in this thread while its still under the P/Train warr... I'm at 40,000 mi. on the clock..

I've been following this thread and hoping and praying that I wouldn't run into this. I had a 1996 Chev 1500 with the 4300 from 2007-2010 (original motor and not rebuilt) with 230,000kms and didn't lose ONE DROP of oil between changes. Not one burned, not one leaked. I would be QUITE DISAPPOINTED that this is an issue 12 years later...

Are you guys noticing this issue around the 30K mile mark? I'm just over 30K (33K) miles and so far I have not noticed a drop.

Mine started sipping oil around 48,000 km (30,000 miles)

I know now when my 2011 gets close to the end of my powertrain waranty I'm going to have to think really hard about doing something else. Maybe within 5 years or so Ford will know how to keep a spark plug in there motors or know not how to make them get stuck in the motor.

I know every manufacture has its issues but it seems to me we should atleast know how to keep a sparkplug in a motor in the case of Ford anyway.

I thought this issue was fixed on their newer 5.4 ?? Something about an extra couple threads for the plugs....

my 07 started the oil consumption with 29k on it. been keeping the report for the fall, and finally the dealer ordered all the parts and then some. it's in shop now.

From what my dealer told me I'm getting the deflector in the oil pan, new lifters, Valves, Pistons, rings, Bearings. the hole shooting match. so we will see.. glad they gave me a new chevy cobalt for a loaner with this nasty winter storm. lol

mtiffinal · February 2, 2011

Picked up the truck today after being in the shop for a week. Got 8 new lifters on the drivers side per PIP4492S. Also got the AFM Pressure Relief Valve cover intalled and piston cleaning procedure per TSB 10-06-01-008A. According to the bulletins, if the problem continues......complete new pistons and rings. Only time will tell.

Couple more side notes;

1) second time in shop for warranty work on excessive oil consumption(1st time was PCV valve cover replacement PIP4492H)

2) no lifter ticking involved

3) they furnished rental car at no cost

4) service writer said he thought GM would continue to fix/repair this problem once outside the warranty period due to all the documentaion, we'll see

5) I had to pay $25 for an oil change

6) currently at 54k

Just wanted to post this up to share and for others who are having the same problem. I will continue to monitor and post as more developes.

Ford fixed the spark plug problem with revised heads in the 2010's. Think they are going to a 5.0 for 2011. Still have the cam phaser noise.

This has been a really interesting thread so far. It really helps those who have oil consumption issues take the right steps to correct the problem (hopefully).

Please enlighten us! ..... Just how do you correct this problem ????? GM does not seem to know!

It seems that GM is just throwing parts at these AFM engines hoping to keep the owners happy (ie., partially satisfied....) until they finally decide to sell them or trade them in ....
