Yeah, I need to figure out what the best LSD additive is and how much to put in.

If stuck rings are the oiling issue with your 3.5, it might be worth it to get the spray bottle to shoot down the cylinders through the spark plug hole, let it sit awhile, crank the engine, spray some more, let it sit for a day, put the plugs back in, run it for a while, then change the oil and add a quart of MMO. Besides, it is a good idea to inspect the plugs if you are burning oil as they may be fouling.
Hmmm, interesting. My plugs were changed about a year ago, so I doubt there is any fouling by now, but you never know. Hopefully the Purolator valve will show some improvement. I will probably do another SeaFoam treatment next time I change the oil also....
