Finally, if the engine is already in the hot season or worn to a certain extent, it is necessary to use high-viscosity oil, such as 15W-50, etc., which will help form a thick film to maintain the oil pressure and reduce oil consumption. After selecting lubricants, how to add it is a science, here to teach you some added attention to the situation of lubricants. Add the amount of oil is not better. If too much oil will increase crankshaft rotational resistance, reducing engine output power, and those excess oil will jump into the combustion chamber, causing the vehicle burning oil, blue smoke, so that fuel consumption increases. Oil combustion residues will accumulate in the combustion chamber walls, the combustion chamber to reduce the space, thereby reducing the compression ratio of the engine; would also accelerate wear of the cylinder and the piston, thus reducing the life of the vehicle. So, when adding oil, be sure to keep the dipstick slightly less than the maximum scale is appropriate; Also master model oil, Oil Change season, engine performance and other factors.
