2008 GMC Sierra 1500 SLT Z71 4x4 Crew
90,000 miles
I bought mine used with 52k miles in 2009. I thought I found a great deal at the time. A few months later was wondering why the oil gauge went to zero during a right hand turn. Pulled the dipstick and not a drop on it!!! WTF!!! only 2600 miles since the last oil change!! had to add 2 quarts. since then I carry two quarts under the hood.
I've also owned only GM. never had to add more than a quart between oil changes even on my '73 C2500. I put over 200,000 miles on my 93 Sonoma (4.3L) and never had to add any oil between changes.
So far I've been keeping an eye on it. Pretty much adding a quart every third tank of gas. Ridiculous! I've been using Valvoline full synthetic since I bought it. One good thing is no smoke so at least its not completely embarrassing.
Since I bought it with no warranty I haven't tried the dealer for any fixes. I've been keeping tabs on several forums to see what others have done to get the problem corrected. So far, and almost 30k miles later, it seems the only fix is a near engine rebuild and to disable the AFM right after. Anybody see another solution?
Over the holidays took a trip to Florida. Did an oil change before I left so I know it was full. Round trip of 1100 miles. When I got home checked the oil and nothing on the stick!! Had to add 2 quarts after 1100 miles. Time for a new engine?....ugh.....
My plan is to start shopping for a crate motor. I'm not a gear head but I've done a few engine swaps. Though this would be my first on a daily driver that still has another 2 years of payments. This is not going to be very enjoyable.
Anybody have suggestions/sources for a 5.3L crate motor? Do I need an AFM compatible motor? I found a 5.3L HO on Jegs but would it be a bolt in replacement? guess I'll call Jegs and see what they say too.
