    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.

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

    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.

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.
    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.
