Lube oil is vital for a running engine; it must have the right viscosity and be changed on a regular basis. As the oil passes through your engine, it picks up debris and particles. If left unchecked, the debris will cause serious damage to your engine. The solution is an oil filter – lube oil filter does exactly what the name implies: it filters the oil and removes particulates before they have a chance to damage engine components. You also can check with oil filter manufacturers for more.
