What kind of oil is used for the 1.5L Earth Dreams engine?
2 Answers
Honda's 1.5L Earth Dreams engine uses 0W20 or 5W20 engine oil. Extended relevant information is as follows: 1. Engine oil is known as the blood of the engine, and it is very important for the engine. If there is no oil in the engine, the engine will not be able to operate normally. In the engine, oil not only serves as a lubricant but also plays roles in cleaning, sealing, buffering, rust prevention, and heat dissipation. 2. When the engine is running, the oil forms a film on the surfaces of various components inside the engine, preventing direct contact and friction between them. 3. Over time, the performance of engine oil will degrade, so it needs to be replaced regularly. If the oil is not changed for a long time, it will also accelerate engine wear. 4. Every time the oil is changed, the oil filter should also be replaced. The oil filter is used to filter the oil. Without an oil filter, the oil would become very dirty after some time of use.
I've studied many engine designs. For the 1.5L Earth Dreams engine, Honda officially recommends using 0W-20 full synthetic oil because it better matches the engine's high compression ratio and fuel injection system. Low-viscosity oil like 0W-20 helps reduce internal friction, improving fuel efficiency by over 5% and preventing premature wear. In hot weather, 5W-20 can be an alternative, but it must meet API SN or SP standards. I also recommend changing the oil every 7,500 to 10,000 kilometers - don't cheap out with mineral oil, as it increases carbon deposits and reduces engine lifespan. Regular oil level checks are crucial, especially after long-distance driving.
