Does Changing to Better Engine Oil Improve Fuel Efficiency?
1 Answers
Changing to better engine oil does improve fuel efficiency. Classification of Engine Oil Types: Full Synthetic Oil: Full synthetic oil offers superior quality, better fuel economy, longer oil change intervals, extends engine lifespan, and reduces maintenance frequency. Due to its excellent cleaning properties, the engine cylinder remains cleaner. Semi-Synthetic Oil: Semi-synthetic oil is formulated using semi-synthetic base oil, specifically Group III base oils internationally, which are refined from mineral oil through hydrocracking technology. Mineral Oil: Mineral oil is primarily derived from crude oil. After extracting gases, gasoline, diesel, kerosene, and heavy oil from crude oil, the remaining product is mineral oil base. Typically, mineral oil is less expensive, but it oxidizes more easily. What is Oil Burning: When the engine is running, the pistons move rapidly up and down within the cylinders, with engine oil acting as both a lubricant and a protective agent. During operation, some oil inevitably remains on the combustion chamber walls and gets burned. If excessive oil enters the cylinder and participates in combustion along with the air-fuel mixture, it leads to excessive oil consumption. Excessive oil entering the combustion chamber also promotes carbon buildup, resulting in higher emissions.
