How often should change the oil in your engine?

In most new vehicles, factory recommended interval for changing oil and filter is usually once every year or every 7500 Kilometros

in passenger cars and light trucks gasoline engines. Some even recommend OEM = Team ORIGINAL OF Manufacturer 10000 Kilometros

oil change intervals. A growing number of OEM their specific mileage or time recommendation and use of petroleum oversight in turn an oil change reminder light when the oil change is required. For diesel and gasoline engines with turbocharger, the recommended interval is typically every six months or 3000 Kilometros

Oil Analysis
a way to know for sure where oil has to be changed is that the oil tested in 3000, 5000, 7500 or 10000 kilómetros. Many fleets do this to optimize their oil change intervals. A small sample of oil (3 to 4 oz.) Engine is taken, sealed in a bottle and sent to a laboratory for analysis. The laboratory carries out a series of tests to determine the properties of oil and pollutants found in oil.

In addition to the loss of viscosity produced by normal use for many miles, the oil degrades per share of the operating temperature of the engine, for the loss of their qualities of additives or impurities in the collection as:

- Carbon, product of burning oil on the walls of the pistons, very close to the rings.

- Fuel: That condenses on the walls of the cylinders at the time the engine is started.

- acidic waste: Proceeds from the degradation of oil and its additives as a result of chemical reactions of this degradation.

-tarry waste or coal.

-

-metal particles, arising especially in new or newly repaired engines. In addition to the dust not retained by the air filter, and serving as abrasive material.
All these extraneous elements, form films or layers that can obstruír duct system lubrication serious damage to the engine.
