At least you have the OPTION for an oil flter. My " Toy Built"rider with a 15.5 hp engine doesn't even have one ! You wouldn't believe the metal shavings that comes out when you dump the oil. But what were they thinking ?!?! So, to offset that mess, I have to dump the oil more frequently. A real pain in the a-- !!!! to boot. Briggs gives you a plastic extension tube to extend the plug hole past the frame. Still leaks and make a mess. You can't plumb out the hole, or it will hit the tie rod for the wheel. So, you're stuck with at least a 5 rag slop job. I'll trade you're Hipa filter engine for my P.O.S. no filter Briggs anyday. ANY filter is better than no filter. Let's see how long I can keep this alive on over 3/4 acre of grass

I can see a piston rod at the starting line !
