Review on 🔍 Kohler (2 Pack) 52 050 02-S1 Engine Oil Filter: Enhanced Capacity for M18-M20, CV11-CV16, CH11-CH16, LV560-LV675, CV460-CV490 by Jeremy Rodriguez

It seemed like forever to get here but one day they were exactly as described. My Zero rev is at least 16 years old and I change the oil with a new filter at the beginning of each season. Here's what I've done with great success, you can try. I use the air pressure in the fill tube to blow out the old dirty oil before pouring in the new. You will be surprised how much is left in the crankcase. Absolutely clean oil has allowed my Kohler engine to run smoothly and without oil burning problems for all these years.
