Some specific maintance questions for my GP 5500
OK, I like over a million people on the east coast was out of power for several days this last week. My GP 5500 ran flawlessly for the whole time (albeit louder than I'm sure my neighbors like (but what the heck, I had power!)) Anyway, now I want to give it some good PM so it works flawlessly again next time. Here are my questions.
1. When checking the oil, do you screw the cap all the way in to get a reading, or just place it in the hole without screwing?
2. The manual says to check the valve clearance after the first 50 hours... I definitely exceeded that, and now want to do that, but can not find any decent instructions on your site on how to check the valve clearance. I'm pretty good at this kind of stuff with instructions, but don't want to attempt this without them.
3. What is, and where do I find a fuel stabalizer because I see in your answers to other questions that you do not recommend draining the fuel, just adding the stabilizer.
Thanks in advance for your answers.

For the GP5500 when checking the oil, you will want to screw the cap all the way down to obtain a proper reading. Just setting the cap into the opening without screwing it in will give you a false reading and can cause the oil to be overfilled. We do recommend checking valve clearances, however, we don’t have any further instruction other than what is located in the manual. If you are unsure of how to check valve clearance, we recommend having it done by a Generac certified service technician. When preparing the unit for storage, we do recommend a fuel stabilizer if emptying the fuel tank is not feasible, but it is stated in the manual to be sure to empty the fuel tank. If needed, a fuel stabilizer can typically be found at your local hardware or automotive supply store. We also recommend that the unit be started at least once every 30 days and be allowed to run for at least 30 minutes. If this cannot be done and the unit must be stored for more than 30 days, the unit should be prepared for storage per the instructions in the manual under the section titled Long Term Storage.
