OK, everybody this is the thing you never want to see, at start up exhaust smokes for a few minutes, then goes away as soon as you start to drive. When driving and go to WOT you smell oil burning, you don't smell any just driving around or under normal accelerating only at WOT. I got a 2010 Limited 5.7 with 56,000 on it.
. I use 5w20 mobile 1 full synthetic, change it when ever the light comes on usually around 5000 miles.
