this is kinda a stupid question but i was changing my oil not too long ago and i completely drained all off it, changed the filter pulled out the dipstick and wiped it off and started filling it back up but when i put in three quarts i always check the dipstick. i dont know why its just a habbit of mine from prev vehicles. well when i pulled out the dipstick it said i was about a 1/8 quart shy of full. i was under the impression that my motor took 4 quarts but i guess i am wrong. i have a d15b8. do they ussually only take 3 or 4?
