Why Don't American Cars Burn Engine Oil?
2 Answers
American cars don't burn engine oil, which is largely related to their road conditions. Because road conditions abroad are relatively smooth, and there are no speed limit requirements, the engine oil remaining on the mesh cylinder walls is less when the engine is running at high speeds, thus reducing the probability of oil burning. Here are some methods to reduce oil burning: 1. Method one: Regularly maintain the car, and also regularly change the engine oil and filter elements, and the air filter also needs to be checked and replaced. 2. Method two: The quality of the engine oil is also very important. If the quality is too poor, there will be many impurities, which can easily cause carbon deposits, leading to oil burning in the Jeep Cherokee.
Actually, American cars occasionally experience oil burning issues too, but the probability is indeed much lower compared to some European models. I think it mainly comes down to different design philosophies: American engines typically prioritize rugged durability. Take GM's famous LS-series V8 engines for example - engineers specifically reinforced piston ring sealing and cylinder block cooling structures to minimize high-temperature oil evaporation and consumption. American driving habits also play a significant role, with more highway cruising and less urban traffic congestion, allowing engines to operate under stable conditions for extended periods, which reduces oil consumption. Of course, fuel quality is another factor - North America's stringent fuel cleanliness standards result in less carbon buildup, naturally minimizing oil burning caused by stuck piston rings. Overall, this is the combined result of design, road conditions, and maintenance factors.
