For a decade I have changed my
oil the same way. I would run it so it's nice and warm, then change the
oil while it's hot and just try not to burn my hand. It's always taken the same amount of
oil, 8.5 quarts. Every time. But today I changed the oil, but with the engine stone cold, and not having been run since late November. After firing it up, checking for leaks, and letting it drain down for the top off, just like I always do, it took 9 quarts. Same Brad Penn 15w-40, same Moroso filter.
