Small Engine Fuel Problems

With the influx of higher concentration ethanol or methanol blended fuel replacing pure petrol over the years most petrol generators and small engines have been experiencing serious problems in the country.

Owners of small 2-stroke engines that mix fuel and oil are finding that such fuels have terrible effects on the performance of this mixture within their engines.

The ethanol pulls water into the fuel, and the water dilutes the dissolved oil in the blend, ultimately preventing it from reaching all of the parts it needs to provide adequate lubrication. Poor engine performance and damage are the inevitable result.


Those owners who are lucky enough to side-step the internal damage ethanol does are still very likely to see difficult starting, rough running and increased smoking from their engines, as those machine try to burn off the dissolved resins and hydrolytic breakdown products caused by the dissolved water in the fuel.

Owners of generators and small engines that run on gasoline and ethanol need peak performance and value from their fuels just as much as the owner of a large big-rig transport truck does. Preventive treatments for ethanol that remediate its damaging effects may be the best answer for many consumers.
