lead to increased fuel consumption (Dieselpartsworld) 2016-02-28    

The 40 reason engine burning oil "
The cooling system of 20 dust
In the water jacket and the radiator corrosion particles, scale and sediment or other product, and water line corrosion, which have a negative impact on the cooling efficiency of the cooling system. Therefore the cylinder caused by deformation will directly cause the loss of oil, such as section #7 and section #8. The defect of the cooling system, causing the engine overheating, some local overheating may occur in the cylinder, causing the piston and cylinder, piston ring abrasion and adhesion, resulting in increased fuel consumption. Overheating of the engine oil sump and the overall temperature may also lead to increased fuel consumption.
21 dirty oil
Not according to the oil drain intervals and oil filter maintenance improper oil will become dirty, the oil blockage piston, piston ring oil gap, lead to such as the reason #17 the fuel consumption rise. Dirty oil will cause the bearing, cylinder, piston, piston ring wear. These wear parts, as explained in the previous correspondence, will lead to increasing fuel consumption. Special note: the dirty oil itself than clean oil consumption is also higher.
