he told me mobil will build up sludge after a while ...
what oil brands work fine in the crossfire srt-6, i have used mobil and castrol also this car '05 has like 300 miles on it now i know y6u can go like 7,000 miles on an oil change.

also i noticed on the tail pipes they are like a little black **** in the center of the tail pipes.
i guess this is where water drips out from first starting the engine (condensation).

anybody else’s tail pipes black ?
