but obtained by adding detergents and dispersants. Mainly through the corresponding engine test evaluation. Good oxidation resistance: Under certain conditions, the engine oil resistance to oxidative deterioration of the capacity, called the oxidation resistance of the engine oil. It is decided that the engine oil use is perishable parts corrosion and deposit formation tendency is an important factor to determine the engine oil using the term. 5) good corrosion resistance: engine oil resist corrosive substances on metal corrosion, called the corrosion resistance of the engine oil. The corrosion resistance index of the assessment of the engine oil is the value through the corresponding engine test rating. Good anti-foam: engine oil to eliminate the nature of the foam, called anti-foaming of the engine oil. When the engine oil by intense agitation, the air is mixed with the oil, it will produce foam, foam if not eliminate, will produce vapor lock, fuel supply shortages failure. The assessment engine oil anti-foaming indicators generated foam pour foam stability. The oil add error method misunderstood: when oil black on oil change this understanding is Timberland Femme not complete. For the no lubricant plus quiet dispersant, the color black is indeed the oil has been a serious deterioration of performance, but the modern use of lubricants are generally added quiet decomposing agent. This quiet agent adhesion film on the piston and black carbon deposition washing down and dispersed in the oil reduce engine temperature precipitates generated, so the colors tend to darken the lubricant used for some time, but this time The oil is not completely degenerate. Misconception two: lubricants can pay the extra amount of lubricating Nike Jordan oil should control the
