If you can find the GM or the Mopar top engine cleaners either one is fine. There are plently of others out there too. The important thing is know how to use it so it gets down into those nasty azz pasted oil control rings. I would probably let it soak for a few hrs after fogging the engine with them. Just be careful not to over do it, just put in enough at a time to slow the engine. Once you think the cylinders are good and coated have someone else shut it off and let it sit for 3-4 hrs.

After changing to Valvoline high mileage 10w30, some sea foam and marvel mystery oil, the oil is still clear after 150 miles. (50 miles with seafoam before the change made it noticeably darker) I have been watching my oil close over that mileage and if its burning any it seems to have slowed way down, I am doing the same trip it burnt a quart on in a few days, I'm anxious to see what the dipstick says when I get there.

500 miles since my oil change, if it's still burning oil it's slowed wayyyy down (before I'd be almost a quart low), Idk if it's the switch from synthetic or the heavier weight oil but it seems to be working! It's also stayed amazingly clear even with seafoam and MMO in there in theory cleaning stuff.
