Hey All!
I have two questions related to oil and filters.
1) I know you can use a filter for a 4.3L on the 3800 to get a little extra capacity. Does anyone have a Fram or GM part number for a correct filter?
2) I just did a LIM gasket here and want to run some oil for a few hundred miles or so to clean out the gunk that was around from the coolant leak and also whatever got into the motor with it being opened up. I have Royal Purple synthetic but I don't want to use that yet. I'd like to run something through first, drain it and then go for the synthetic. What should I use? A "high mileage" oil is there something else that might give it a good cleaning? Plain oil plus Marvel Mystery Oil?
Thanks!
Adam
