haha that reminds me of my 3.1... About 2 months ago I was driving my 3.1 and the oil pressure gauge started getting lower and lower, well my other 3.1 car identical to that would do the same thing when it was like 1 quart low on oil. So I didn't even check the dipstick and dumped a quart in. Oil pressure would go up to like 25 so it was good enough for me (usually runs at like 70-75 though), but it would go back down after like a week so I just kept putting a quart in every week. I knew the engine had some major problems (blown headgasket AND blown lower intake gasket among a few other things) but I had to get to work and school and stuff and I'm gonna L67 swap the car in a few months anyways so I didn't really care if the engine went. So I tore the engine apart to fix the issues with it and pulled the drain plug and it filled up 2 7 quart drain pans.
Ooops..... The blown headgasket and LIM gasket were causing coolant to go into the oil, making me lose oil pressure, so i'd add more oil and that would fix it for a little while.
I got a good laugh from it....
