Again, machinery dealers can make recommendations on cleaning and service. T Dirty air cleaners restrict the flow of air needed for the combustion process. Less than sufficient air for the combustion process results in excess fuel in the fuel-air mixture and fuel consumption increases with less available power and higher fuel costs. Look for black exhaust smoke or check the air flow indicator found on most air cleaners. Service the air cleaner or replace the filter if needed.
T Use the proper viscosity of oil in the engine to maximize engine efficiency.
Oils that are too thick decrease power and lubrication and increase fuel consumption. Change the oil on a recommended schedule to remove contaminants that can reduce lubrication and increase friction between moving parts. Contaminants change the viscosity of the oil and can cause corrosion of engine parts if left in the engine too long. Today s engines only need a 2 minute cool down even after running long and hard. Long periods of idling not only increases fuel use but can also lead to carbon build up on injector spray holes and valves.
