How to choose the lubricating oil

which automobile's lubricating oil on the automobile uses to include: Motor oil; Automatic transmission oil (ATF); Manual transmission oil; Limitless transmission oil (CVT); Differential device oil; Diverter oil; Brake fluid and so on. The different brand's automobile uses the lubricating oil is dissimilar. Should better use this vehicle brand the special-purpose lubricating oil. If has the condition, may choose a better machine oil. Generally the high compression ratio's automobile, is easiest to use including the belt turbosupercharger's automobile the high marking the synthetic motor oil. Engine machine oil foundation oil mineral oil and synthetic oil. The mineral oil merit is: The price is low. But uses in the high compression ratio high temperature engine is inappropriate. Its shortcoming is: The engine elevated temperature service can have the carbon deposition, accelerates engine's attrition. Synthetic motor oil's merit is: Better resistance to wear; Better sanitary; Higher anti-high temperature oxidation resistance; Higher fuel oil efficiency; In protection draindown system's three Yuan catalysts; Better greasy dirt dispersivity; Low volatility; The obvious low temperature superiority, can satisfy the different local winter oil used, starts coldly, reduces the attrition. Engine machine oil several ranks: SG; SH; SJ; SL. The present age gasoline engine's automobile is using SJ or the SL rank machine oil generally. The upscale vehicle Beijing area uses SL5W-40 or the SL0W-40 machine oil generally. W is better on behalf of the low temperature viscosity rank digit smaller low temperature performance. Behind Representative W digital: By 100 degree Celsius time viscosity ranks. The digit is bigger, the viscosity is higher. May divide into: 20-60. The brake fluid generally uses DOT3 or DOT4 now. This oil for the thermostable high speed brake fluid, has the water affinity. Generally two years or 60,000 kilometers must replace one time.
