The mixed use of different brands and grades of motor oil will also cause the following hazards:
1, the exhaust pipe smoke abnormality. The viscosity of the oil is likely to become thinner after the oil is mixed, resulting in a part of the oil is brought into the cylinder combustion, so that the engine blue smoke is "burning oil". The oil mixture may also make the cylinder seal is not tight, it is easy to cause the engine smoke.
2, accelerate the accumulation of oil sludge. The formation of oil sludge in the oil will reduce the cooling effect of lubricants, so that the engine is easy to form a high temperature, which leads to engine failure easily. Some oil sludge will also block the set filter, oil, which will easily lead to poor lubricant reflux, the engine will not be lubricated, the consequences are very serious.
3, piston rod or piston ring wear. Mixed oil may reduce the sealing performance of the piston rod or piston ring, which can easily lead to piston rod or piston ring discoloration or damage. If you continue to use mixed oils, it can cause severe wear on the piston rods or rings, affecting the life of the engine.
4, serious wear piston and cylinder barrel. Different brands, different grades of oil mixed use, its anti-wear properties may be a great change, which will lead to the formation of lubricating oil lubrication film is destroyed, resulting in serious wear of the piston and cylinder barrel.
