15,000 mile oil change

[fabsroman]

Skinny,

Are you serious about the WD-40? I have a couple gallons of it and it would probably clean out the motor pretty well, but I want to make sure that you aren't joking about it before I try to put 5 quarts of WD-40 in my motor.

On another note, my brother didn't change the oil in his F-150 for about 20,000 miles and the oil came out like sludge. In fact, it didn't even start to drain until a screwdriver was poked up into the drain hole.
