Thanks again for you and David's advice & help (via Rich) I talked to my stepdad a moment ago and he mentioned that I should run the engine with this oil change for a time (a week or so?), then change it out and use some kind of valve cleaning additive (I forgot the name already), and replace a 3rd time, to de-gunk the engine. God knows it sat unused for a long time (I'm not even sure, I need to ask the guy). I'll try a heavier oil weight with my 3rd oil change.

Yeah, it's funny about the battery... I was saying that the day we tried to start it up for the first time. I don't know, maybe my car communicates with me telepathically... it told me the ECU was bad back in May, when we couldn't figure out why the fuel pump wasn't sending fuel to the engine -- yet passed all the tests... "Can we get a telepath out here? My car is having problems."
