Apparently there are 2 oil pans on this moving van. I cannot locate the plug for the reserve oil pan. This model takes 9 quarts in the regular oil pan, 1 quart to fill the filter, and 6 quarts in the reserve oil pan. It belonged to Uhaul and they had oil change directions on the air intake, but they are mostly unreadable now. But they do refer to 2 drain plugs and 2 oil pans. I can only find the main pan/plug.
