Potentially stupid question here: can you swap an oil filter without draining the oil from the pan?
I have a vertically mounted spin on filter on my 2007 Camry 2.4L. I am running HPL EC through it for 3000 miles and want to see what that filter caught from the HPL EC at the next change. However, before I swap the oil, I want to run a can of BG EPR through it. I figured I would sacrifice a PH3600 for the 20 minutes or so that the BG EPR is running through it both to see what it does on its own and to be safe from overloading the existing filter that might have caught junk from the HPL EC, then drain the oil and put on a fresh filter.
However, never having had a reason to do that before, I am unsure if an excessive amount of oil will drain from the filter housing if the oil isn't drained from the pan first? I would rather not have a big mess and the need to put fresh oil in it for 20 minutes running the BG EPR.
