Bought this 1850 watt Coleman generator seven years ago. Used two years during ice fishing season only and have kept at home in bsmt since as a spare in case home power was ever lost. Never could get after-market hour meter to work. I estimate about 600 hours. Fuel drained and oil changed when stored. Runs great. 5 galllon auxilary gas tank available if you don't low ball me to bad. Bought Honda 2000i. Don't need this one.  $300 b/o.
