How much oil 454

But on your 77 Itasca, its 7 quarts with a new filter, and 6 without a filter I always wondered why they even list a capacity without a filter change Thanks, now I can change the oil and calibrate the universal dipstick. I have read there were several different oil pans on the depending on the vehicle it was used in which impacted the oil capacity.

I reserve the right to reject your reality and substitute my own Dave's Place. Allegro might have added an extra capacity oil pan? Our 89 Holiday Rambler uses the same as our old 77 Itasca I do know there are different pans for different trucks, i assumed allthe rvs would be the same though. I now have the oil filter and the oil but we have a light breeze today about 40 mph and its only 45 degrees.

I am hoping it will warm up so I can work on the outside projects. Ok next question. It appears I have a 2 quart filter installed. Napa gave me what looks to be a 1 quart filter.
