Part of the secret to anything mechanical lasting more than a couple of years is proper and regular maintenance. In the case of the Generac here, once a year you need to change air filter, oil filter, spark plugs and motor oil to keep your warranty current. Wired lets the homeowner do that if they wish so long as they document the maintenance and can prove they did, in deed do the scheduled work at the scheduled intervals and did it properly and correctly. I am a mechanicaly inclined guy so I opted to do that, according to the owners manual and precisley as instructed with genuine replacement parts. OK, so what does a "kit" consist of?Well, in the box there is a spin on replacement oil filter and a dandy paper funnel to put the oil in your motor, a little handy spark plug wrench and two Champion replacement plugs, an exact fit air filter and a drop cloth to help with any spills. I have seen guys charging 40 bucks or more per kit and when I found this provider offering the same for only 15 bucks a pop, I said "stock up". And I did just that. Exactly as described and exactly as the factory originals because it is factory original merchandise at an affordable rate. Oh yeah, our Wired technician, Joe told me to use a high quality 10/W/40 oil when changing it out. Takes 1.9 US quarts which includes oil filter capacity when changed every year. I selected Mobil fully synthetic "High Mileage" oil since this is an air cooled motor and who knows when it may be used for considerable days on end in the event of whatever perils lurk out there? I know my other Texas based reviewer says he does not recommend using synthetics in warm climates (Based on what???) I wanted to back up my recommendation to use synthetic oil in ANY air cooled motor with the following recommendation from aircooled.net's own tech talk forum "Since synthetic oil has better heat transfer qualities than dino oil, your internal engine temperatures will be lower. Things like bearings, especially, will not operate at as high of a temperature as a result. The wider range of temperatures that synthetic oil can withstand is well suited for the air-cooled VW engine. With head temperatures normally between 300-350 degrees, synthetic will not breakdown while lubricating the valve train components at the heads. The better lubricating properties of synthetic in general will lead to a longer engine life as well. On average, when synthetic oil is run in an air-cooled VW engine, head temperatures stay the same, but engine oil temps reduce by anywhere from 10 to 15 degrees. This is in identical engines that have all the correct cooling tin in place, and are not suffering from overheating to begin with. Important note: Do not run synthetic to fix a hot running engine. Find the real reason it's running hot, and fix it!" There you have it. Your Generac is also an AIR COOLED engine and is made of the same materials as a VW, Corvair or any other air cooled engine. This is THEIR recommendation, not mine. Go for it. ### ⭐⭐⭐⭐⭐ Easy DIY maintenance—saves hundreds *by on Reviewed in the United States August 27, 2025* ⭐️⭐️⭐️⭐️⭐️ (5/5)Don’t pay $300 for someone else to do it—this kit makes maintenance a breeze!
