Was your oil discolored at all when you changed it? Any white smoke out the exhaust?
Burning oil & white smoke sound like a leaky head-gasket to me.
my oil was just dirty, it was a very dark brown, almost a black, and im sure i might have a little smoke but im not 100%, i dont have any smoke when idling but mostly likely when i stomp on the gas i do.
and also i have lifter tick, and its getting worse over time... i changed my oil today with 3 quarts 5w-30 pennzoil, and 1 quart 10w-40 pennzoil, and 1 pint of marvel mystery oil
