Hello all. New here from Indiana. Just recently bought a 2007 Silverado crew cab new body with the 5.3 flex in it. It's been a great truck so far, but I've got one concern. I've heard a ton about these things using a ton of oil due to the active fuel management. I just recently did a cai and a throttle body spacer. I will be doing the dynatech supermaxx exhaust in the near future. But for now, I have a diablosport tuner on the way so I can tune out the afm. Am I going in the right direction here? Or is there more I'm missing? Any and all help is greatly appreciated guys!

Thanks, Alex

 

Welcome to the site!

whats your overall goal for the truck?

 

They tend to use about a quart every oil change. My 2000 does anyways but my 07 doesn't use but 1/3 of a qt. It's from the pcv setup rather than the dod.

 

My intentions are to have a good street/off-road truck that is reliable. It's using about a quart every 1600 miles. So I'm goin to disable the afm with my tuner and see if running 8 all the time helps. I really don't want to do internal motor mods yet because I owe on the truck and it's my DD.

 

thats what i would do. i run stp oil treatment also.

 

Welcome! My truck had the same problem, and I installed a new improved gm PCV and it went from burning a qt ever 1000miles to maybe 1/4qt every 3000 miles. Not to sure if this will help on the newer nnbs motor, but it is a cheap part to try!
