Ethanol Free Gasoline

Ethanol Free Gasoline available at Combined Energy Services

Many gas powered engines, including classic cars, motorcycles, ATVs, boats & personal watercraft, snow-blowers, snowmobiles, chainsaws, lawn mowers and more – can experience adverse issues from ethanol-blended fuel (E10 gasoline). Because ethanol attracts and absorbs water, it can cause phase separation which can result in decrease fuel efficiency, engine problems and lower performance. 


Using ethanol free can increase fuel efficiency, reduce engine problems and increase performance. For small engines that are used periodically and those who need to store gasoline for extended periods of time, the chemical properties are destructive to rubber, fiberglass, plastic and other composite parts of the fuel system and engine. This may result in carburetor damage, clogging and/or plugging of fuel injectors and ignition failure. By using ethanol free you can avoid the above issues.

Off-Road Diesel

Off-Road Diesel available from Combined Energy Services

Off-road diesel can be used for many purposes. For the past 40 years, CES has provided direct to equipment and storage tanks on job sites. For the first time, customers can purchase at the pump!


This fuel is meant for vehicles that are not operated on public roads.


Certain federal and state taxes do not apply to off-road (only) use fuels in turn making the price cheaper than on-road diesel. We offer actual dyed “off-road, low sulfur diesel fuel” (15 ppm sulfur which meets US EPA regulations) as opposed to clear “on-road” diesel. In Pennsylvania, we offer a maximum of 500 ppm sulfer to meet the USEPA requirements. Some personal uses include farm equipment, construction equipment, forestry & logging operations, generators, portable trailers and portable light towers.
