on all of my filters i uses a fat 2" strap wrench, tighter you turn it the tighter it grips,
any good auto parts store should have one, mine has a long 6" bar that attaches to a 1/2" drive so its allows you to get up in tight spots

Onan Oil Filter Wrench - $7.59 This type wrench is the only thing I found that will fit.

I 2nd that recommendation.

Unfortunately, I have found that the original filters are way over torqued and may even have been installed with dry rubber seals. Destroyed more than one filter trying to get them off.

You can purchase a set of "cup" type oil filter removal tools from Harbor Fright on the cheep.

on my onan 5500 marquis, i use a 3 jaw adjustable oil filter wrench from napa, part # 775-9018. i don't remember the price. it helps to put a rubber band around the wrench to keep it tight to start with. there is just enough room for this wrench to fit.
if the filter is too tight for this wrench to work, drive a large long screwdriver through the filter at an angle and make a mess.
when you install the new filter, oil the gasket ring and only tighten the filter about 1/2 turn by hand after it seats.

Most people over tighten oil filters. I have been changing my own oil for over 35 years and I only have to use my hands to remove the filter.

Also, make certain the rubber gasket stays on the old filter & doesn't stick to the engine block. -been a mechanic for 25 years & did it once. Trust me, it'll never happen again!

Another tip. The filter will come loose easier if it is warm. The only time I ever had to resort to a screwdriver and worse was the one time I attempted to change oil and filter on a cold engine thinking it would be less of a mess.

Never change oil on a cold motor.
