    I was on another GM Chevy truck forum and read about 24 pages of the newer trucks burning oil after as little as 12k miles!! I put almost 300,000 on my old 94 Z-71 with a 350/ 5.7 that didn't burn oil. Mine now has a whopping 23,800 miles on her with the little 4.8 and so far so good. I've owned Chevys and GM cars since the 60s and never had this trouble......I would hate after all these years to have to trade her in for a FORD!!! lol. Is anyone here experiencing this? It has really got me paranoid now! :gasp:

    Do a quick search on the forum. There are multiple posts about this issue. Many people are experiencing this. GM has multiple "fixes" for it. Including, new valve covers and a piston and ring replacement.

    Thanks Pikey, I will. I bought my 08 in October so my 5 years warranty will be up next year- just my luck! I see you had a 95- I might just start looking for a old 5.7 Vortec on the old body style with low miles. I will miss my 4 dr crew but will have to find an extended cab. I can say my old truck was a lot tighter than this newer one. I heard this from others before I bought mine and think they're right. I don't like the sound of even thinking about pistons and rings with such low mileage!

    It all depends on the specific motor. My 2002 5.3L burned no oil when I sold it at 140,000 miles and still does not with 165,000 on it. (the kid that bought it stops by to show me his mods). My 2003 5.3L with 140,000 lost about a quart every 2,000 miles. My 2005 5.3L with 140,000 miles does not burn oil.(yet)

    That is great to know and from what I've read you are one of the lucky ones. It is for the 4.8- 6.2. I believe it has to do with the AFM, whatever year they started? Here's what I read:

    The oil consumption issue is primarily an issue with the 07' and up 5.3L engines with AFM. The 4.8 and L9H 6.2L engines don't have AFM.

    I LOVE my '95! Best looking truck ever to come out of the Chevrolet (or any other) assembly plant!

    Yeah I still love the old body style too. I had 94 Z Ext cab step side that was Indigo blue. I do like my new body style but it sure is a lot wider than my old Z and harder to get into tight places! Lol


    Good looking truck ya got there!! :great:

    Also [MENTION=16459]chevy[/MENTION]guy69 the way you have prolly drove your pickups is probably pretty good, and all those other people that say they start to burn oil they have probably drove the pickup really hard. Thats how i see the thing with vehicles, if you drive them nice they dont break, if you drive them like they are a pile of junk than they i would think that they would end up breaking. But thats just my opinion.

    The 5.3L using oil is a very minor problem. My 2008 used about 1/2 qt every 5K miles. ALL engines use a little bit of oil between changes.

    GM has probably sold over 2 million trucks with 5.3L engines with AFM since 2007. If it was as huge a problem as people make it out to be, GM would have discontinued the engine.

    I've never seen a Tahoe with a V6, as a matter of fact, I don't think Chevrolet has ever put a V6 in a Tahoe.

    The 6.2L (L94) has AFM as well. The L9H 6.2L appears to NOT have AFM. The L94 engine is used in the Escalade. I cannot verify that the 6.2L in the Silverado has AFM or not.

    My 2012 Silverado CC 4X4 6.2L with 373 gearing comes equipped with the L9H non afm engine.As do the 4X4 6.2L Silverados with 3.42 gearing.

    Did you get the Max Trailering Pack in your Silverado? IIRC that's the only way to get 3.73 gears.
  14. O'Brien

    O'Brien New Member

    Yup. Mine is the Max Trailer Pack. However as far as I understand all of the 6.2L equipped silverados be it 2 WD or 4 WD have the non afm 6.2L. It is only available in Ext Cab or CC versions.

    So the 6.2L AFM engines are in the Escalades and Yukon Denalis it appears.

    That's affirmative. At least everyone I've seen.

    That is very true of how ppl take care of them. I baby mine and the maintence is like clock work. Now back in the day I was hard on them and only knew 2 speeds- wide open and stop! lol.

    Do you have to run premium gas in that 6.2L engine?

    Yes. The L9H 6.2L calls for 91 octane or higher.
