This is straight from Onan...
Gasoline Engine Oil Quality – Use oil meeting any of the following API
performance categories: SJ, SL or SM where SM is currently the highest quality
available. Look for the “Energy Conserving” designation to optimize fuel economy.
As far as the weights go,we all have different needs in the different regions we live and use the generator in.
The most common issue with Onan generators is lack of use and old gas..Again from Onan:
NOTE: Fill up with fresh gas! The single most common service issue is stale or
contaminated fuel. Always use fresh gas! The gas should not be more than 30
days old. Fuel stabilizer extends the life of your fuel. Stale fuel clean-out is not
covered under your warranty.
