We’ve had our Honda EU3000is generator for about two years. The only maintenance I’ve done is to run it for an hour about once a month and add STA-BIL fuel stabilizer to the gas tank. After checking the maintenance schedule in the owner’s manual, I decided to change the engine oil, clean the air filter and put the battery on a Battery Tender Jr. trickle charger.
