Drain the
oil and then put in 7 quarts of
oil. That's your add mark on the dipstick. Now add another quart of
oil. That's your full mark. The filter and cooler don't have anything to do with it.
Now start the engine and let it fill the cooler and filter. Check your dipstick and fill to the high mark on the dipstick to bring your pan back to 8 quarts.
