Factors that could make engine oils degrade faster in hot climate
We are writing this article to advise owners not to exceed manufacturers oil cnange intervals in Nigeria because of the presence of factors that could cause faster oil degradation. Below are some of the factors explained.
- Dust - Relative to the western world, our environment is very dusty. Coupled with poor maintenance culture of not replacing bad engine intake air filters, dust finds its way more easily and hence contaminate and degrade the oil faster.
- Substandard oil filters - The engine oil filters that are mostly on sale in Nigeria are substandard. This is so because of the fact that many Nigerians prefer cheap products. These substandard oil filters are not able to filter very micro particles (like little particles of dust, iron fillings, carbon) which causes the oil to degrade fast.
- Maintenance culture - Some Nigerian mechanics are known for bypassing or condemning systems that should work. For Instance, when emission systems are not properly working, the engine oil gets polluted quickly. Another practice that can cause fast oil degradation is the running of radiator cooling fan in its maximum speed always by doing a direct power connection to the power source. This causes the oil not to reach its normal operating temperature,. When moisture is not burned off at operating temperature, the oil degrades.
- Lack of proper emissions check - As stated earlier, a car with more emissions will contaminate the oil faster especially with carbon deposits.
For these reasons, oil change intervals should be strickly followed by car users in Nigeria else they risk premature engine wear.
