Average Auxiliary Engine Fuel Consumption by Model

July 2013 Update: A WSA Member reports he has long deducted ALL fuel used while on parking lots in his state (Florida). They support the deduction via GPS tracking, which shows how long they are on private property. A deduction based on the total amount of fuel used is taken based on the amount of time the sweeper is verifiably on private property. If you have information on this topic, positive or negative, please let us know.
In the following, fuel usage and other information is shown for most twin-engine parking sweeper engines. The engine data were updated in March of 2016. Check the the engine your sweeper uses and you will find it is probably on the chart. If not, please let us know what model of sweeper and engine you are using so we can add it to this chart! Calculations are based on the engine manufacturers’ fuel consumption curves, utilizing an average operating speed of 80% of total available RPM. Your actual fuel consumption may very due to factors such as engine wear and surrounding environmental conditions. Remember: The IRS requires that a factor is included to allow for warmup and idling. If you operate your sweeper above 80% of maximum RPM on a consistent basis, you may want to consider using a higher number; however, the fuel shown to be used in the chart we believe represents a defensible amount for most applications. If you do use a larger number be sure to also include a factor for idling and warmup. If you do operate your sweeper consistently at such a high RPM setting, you should also check your flaps and other components for wear since it is unusual to need to operate a sweeper at such an RPM level in the usage for which it is designed. It is strongly suggested that you consult with your CPA, attorney or other trusted tax professional for more information on filing for, and receiving, your fuel tax rebate for auxiliary engine fuel used by your sweeper.
