Fun little story here, my buddy has(still has) a 93 Accord that he basically races everywhere he goes it has 250K+ and probably has never had a real oil change. I remember one time stopping for gas and he checked the oil and put 3 quarts in and it just hit the dip stick (I think it's a 4 qt car) and he was like ok we are good now. That was in 2002 and the car is still running.
