From my 1999 Owners manual, the engine oil capacity is approximately 4.5 qts (with a filter change).

Theres the ticket, depends on how long you drain it for too and how much is still inside the block, plus oil cooler/remote mount options adding/subtracting to it. if its overfilled the crank will aerate the oil, frothing it and making a nice bunch of airbubbles for the oilpump to suck up.

Nice. I have a Schumacher SL65 in the glovebox for jumps as well



I did that once a week for about two weeks to help with blowing all the stuff (carbon) out and because I put it through some hard use. Heat, heavy throttle, hours long drives to/from/in NYC and driving fast there too, general "beating it up" a little bit as per ITU (Italian Tune-Up.) This truck was run a couple ? weeks on 5 cylinders so Cylinder #2 needed some love, plus the SeaFoams from the previous engine that have not occured since the new brake booster, and the extensive throttle body cleanings that took place before I found a proper intake piece (the Hat saga.)

They say "carboned up" = higher compression so I also wanted to see if things smoothed out. For what it is worth, they appear to have..

I gassed it up regular gas last few days, I think everything is about as clean and smooth as it is going to get.
