Landfill gas engines need to withstand the extreme levels of oil degradation caused by higher operating temperatures, as well as the by-products of the combustion process of the gas fuel itself which can lead to high levels of contamination. When a landfill gas engine is commissioned, the oil change intervals are initially determined by the recommendations of the engine manufacturer and these can vary from 500 to 1,500 operating hours. The variation in quality of the landfill gas combined with the variable load on the engines can significantly affect maintenance intervals.
