Who have a 4×4 should consider certain additives for oil, these allow a longer duration in the life of the engine.
The TTs are vehicles that face all kinds of climates. At the same time, they may face adversities such as water or dirt inlets to the engine. Therefore, the oil in a 4×4 must have certain properties necessary for the length of the engine.
What is the function of the oil in our engine?
Avoid overheating, using an oil film between the metal parts to prevent friction. Its types are monograde, which works at a single temperature; Multi grade, at various temperatures (usually comes with extra additives that increase the corrosion protection you can have); Synthetic, especially those that have a long route on / off road (because they are of longer duration and their change should not be so fast).
What additives should you use in the engine of a 4×4?
- Extreme pressure: Very important because it reduces the friction between the metal parts. Favorable in diesel engines, as it saves energy and gives them a higher speed at start-up.
- Anti-oxidant: Optimizes the operation of the oil in high temperatures, can be associated with the following additive.
- Detergents: It prevents the appearance of layers of dirt in parts of the engine that carry the highest temperature. If you have an off / road operation for deserts or dunes, this additive is advisable because the heating is given in greater intensity.
- Anti-foam: It usually appears by use of other additives (as above). It expels quantities of air that appear in the oil. It helps the engine in conditions of much wind and speed.
- Antifreeze: It gives good fluidity at low temperatures, useful for handling in cold or snow.
- Anticorrosive: It is like the extreme pressure, as it gives reinforcement to the oil film, preventing the rotation of metal parts of the car, overheating the engine.
- Dispersant: Mud or sludge, as well as residues of fuel or other liquids may form solids in the engine crankcase. This additive helps prevent this problem.
- Basicity: All combustion brings consequences. Acids can form on the engines, especially if they are forced into complex access roads such as handling on branches or rocky terrain.
