I am trying to replace the oil my 1995 volvo 280 outdrive. I have completley drained the oil and am trying to put the correct amount of oil back into it. I tried loosening the dipstick and and it is completley stripped so I looked in the manual and it says 2.5 quarts but I want to make sure, does anyone know how many quarts this thing takes? It just seems that 2.5 quarts is a lot. It would be nice if it was as easy as the mercruiser.
