Engine oil is used to lessen friction from all the moving parts in the engine and prolong its life by decreasing wear and tear. It also acts as a coolant in extreme temperatures and can help trap carbon particles from causing damage to the engine's parts. But there are two types of engine oil for your vehicle to consider and one type of oil may outweigh the other through the benefits it offers.
- The early years of synthetic oils
In the early years of synthetic oils used on cars, they got a bad reputation for leaking. The seal on the engine would shrink if its swell rate was lower than what is required by the synthetic oil, causing the oil to leak through the seals in the crankshaft and rocker cover. Now, if the swell rate was higher, the seals would expand and also cause a leak. After a car's owner changes back to regular oil, the seals having been worn out, would still leak through. Synthetic oils have improved through the years to be used efficiently in cars. Synthetic oils have been around since the early '70s; it has been used on commercial airplanes, jet fighters and various military vehicles before they were launched for commercial use in regular vehicles. Unlike the high performance engines that the synthetic oils were proven to be effective with, regular car engines weren't prepared to handle the early composition, so manufacturers had to refine the ingredients to perform better on ordinary vehicles. Synthetic oils flow much faster and better than ordinary oil and can withstand extreme temperatures from the engine, either hot or cold.
- Regular Oils
Regular engine oils have been around longer than synthetic oils and have proven to have drawbacks, thus the reason for exploring better alternatives. Regular engine oils usually turn dark with use for long periods of time and regular oil changes have to be scheduled to ensure the oil doesn't cause too much damage to the engine in the long run. Although it is recommended by some to use regular oil on new cars to break in the engine's parts, synthetic oil is substituted after a while. Regular oils do not perform very well in extreme temperatures as it thickens in extreme cold temperatures and causes over heating in hot temperatures. This type of engine oil contains contaminants that can wear down your engine considerably and can be hazardous to the environment as well. The regular oil in your engine turns to sludge and without proper disposal when you have your oil changed may have serious implications to the environment.
Synthetic oil has been proven over time to perform better than regular oils. You change your engine oil less since it remains consistent over longer periods of time.
