Before I go on, let me say I DO follow maintenance schedules and I also run at least synthetic blend (and sometimes full synthetic) motor oil in the below engines (I NEVER run conventional oil in them).
That having been said...
I've been running Advance Auto Parts number AA3614 ($2.88) on both my Kohler 15hp CV15t's for over a year now, I also run AA oil filters on my '88 bmw 325 and never a problem.
I recently acquired a 25hp Kawasaki on my Everride, and the AA-4967 fits that (also $2.88).
Yes, I get tired of paying big money for stupid parts, too.
p.s.: The ONLY time I do not run synthetic oils is during the critical first 8 hours or so of break-in period for a NEW engine... You HAVE to run conventional oil during that time or the engine will not wear (meaning it doesn't break in).
p.s.s.: The reason I run at least synthetic blend is because I don't always remember to check the oil, and back in my first year I seized an engine. Nowadays, I don't care, I let the engines go for a month sometimes without checking the oil, synth is THAT good!
Matter of fact, you probably don't even need the oil filter, thou it does seal that hole rather nicely :laugh:
