So far so good
Size: 2500 Watts / Red
I've used this generator a few times and it is well worth the money. It is VERY quiet on eco mode and not so loud on regular mode. This is perfect to have just in case the power goes out or you just want to show off at events with this quiet generator and a small ac unit or high-volume fan. I would buy it again ... show more

I’m doing van life and bought this to top off my battery bank when solar isn’t enough. 1st off, I’m glad I bought this- I didn’t realize it would be as significant of an asset as it has proven to be. I used it more in the winter (less sun) than I do in the spring/summer: in the winter I would run it for about 3-4 hours a day, couple or few days a week… Here’s my notes: -As others said, run it once when you get it with regular (don’t need premium) gas for an hour, and IMMEDIATELY change the oil. I think the manual even says to do this. You’ll notice when you change the oil that the used oil looks like someone added glitter to it- that’s the metal shavings of the engine break in. I’d hate to think what would’ve happened if I hadn’t done this. - Of course don’t use it in the rain, but it didn’t seem to like when the air was damp and the ground was wet after a rain either. I have used it when it was sprinkling rain and it worked, but I wouldn’t make a habit of it. -The cap (that you have to vent to “open”) can be temperamental. I’ve taken the whole cap off a couple times to make it run. - When to change the oil..? It will tell you- it uses oil when running and it will start being harder to start, won’t run unless totally level, and finally, the oil light will come on when you pull the start. Change it with 5/30 and boom. Good as new! Been almost a year of running weekly, and it’s still solid 👍🏻 I’d buy again!!! ... show more

YOU NEED OIL - Here's the spec on maintenance
Size: 2500 Watts / Red
I got my generator yesterday. They are NOT shipped with oil (I knew this, but everyone doesn't). I couldn't find the spec for it online, so I waited for the unit and the owners manual to show up. Here's the information that I wished I could have found so I could have ordered everything all at once: At normal temps, you will need 16.9oz of 10w-30 4-cycle oil to fill it. It did come with a nice little funnel to add the oil. At cold temps (below 25 deg F) use 5w-30. Over 80 degrees F regular temps, use 30 weight. I'm not sure when I'll be using mine, so I've got the 10w-30 on order. Oil should be changed after the first 10 hours of use, then every 6 months or 100 hours of use. The spark plug should be replaced every year or 300 hours of use. I found a part # in the owners manual (100009386) which I think is a Champion L95YC plug (I found it via a Google cross-reference, so I'm not 100% sure)... I haven't confirmed that yet, but I bought 2 of those and will compare. The manual specifies gap 0.6-0.8mm (0.024-0.031 in) tightened to 10-20Nm torque (it comes with a plug wrench). There is a washable air filter in the unit, clean every 3 months or 50 hours of use. Wash it in liquid detergent (ex: Dawn dishwashing liquid), rinse thoroughly, wring out in towel to dry, pour engine oil over filter, work oil through filter, squeeze in paper towel to remove excess oil, re-install. I tend to keep gasoline (I buy premium from a good gas station like Shell/Chevron) in my garage for a year. I use Stabil gas treatment in it to keep it fresh and, every spring (spring cleanout), if I haven't used it I'll pour the gas into one of our cars and buy fresh. NOTE: The gas storage/quality/stabil tips are mine... the manual says to use regular gasoline of 87 Octane or better. -------------------- My oil arrived yesterday. I added the 16.9oz of 10w-30 4-cycle oil I bought (branded Generac) and a bit of fuel (93 octane w/ Stabil added for longevity). Gas cap vent open... choke out... red fuel valve to open... one gentle pull and the engine starts right up. I slid the choke in and it purred beautifully... even quieter than the Yamaha suitcase style that I had years ago (and sold with a trailer) that was supposed to be the quietest in the class. I'm very happy so far! ... show more

Primitive 10 day camping trip review
Size: 2500 Watts / Red
I rarely leave product reviews however I always read reviews before making an expensive purchase. I took the family on a 10-day camping trip at a very popular state park where generators are not allowed during quiet hours at 10 pm. This generator was quiet enough so it would not be noticeable unless you were standing under 75 feet from our campsite. When I first got the generator I gassed it up with super unleaded and premium oil and ran it for 10 hours to break it in. The generator started on the first pull and all was well. I changed the oil and went on the trip. After the first few days of running the generator for 15 hours a day, I ran out of gas in my can. The generator would run around 10 hours on economy mode only running 6 fans and some cell phone charging stations. Well, I went to refill my gas can and because where we were I bought regular unleaded because the price for super unleaded was super high. This was my demise. That night the generator would run an hour and shut off, then another two hours and shut off. I was super frustrated and ready for my money back. The next day I thought maybe I should try to change the oil again. It didn't help the same problem with shutting off after an hour or two. On the 5th day of my trip, I figured why not drain the gas and go back to super unleaded. Well, surprise surprise, the little sucker is bougee and only wants high octane fuel. I never had a problem for the reminding 5 days. Ran like a champ. I have now almost 200 hours running it. So, with good high octane gas and changing the oil often this is an awesome buy. ... show more
