This engine holds 7.5 quarts of oil in the crankcase, but will be perfectly fine running with 5, it just won't pull 1G in a corner for very long without starving for oil
Interesting. My brother just purchased a 96 Caddy Northstar. I inspected it with him. Owners manual says 7.5 quarts with filter (no mention of hot or cold by the way) written in paint on the valve cover is 8 1/2 quarts with filter. So which is it. We asked the dealer to interpret the apparent discrepency. He said, we use 7.5 but always add a little more for this engine. So, still in the dark. Suggest going by the dipstick.
Oh, by the way, it also states in the manual that the use of synthetic 5W30 or 0W30 in very cold climates is acceptable. Sort of blows the dino only theory!
