What type of engine oil should be used for motorcycles in summer?
2 Answers
In summer, when temperatures are higher, motorcycles are suitable for using engine oil with a slightly higher viscosity, with a grade of SF or above, and a viscosity of 10W-40 or 15W-40. Below is a related introduction about engine oil: 1. Engine oil brand: The brand of engine oil is not very important, as long as it can be guaranteed to be genuine. It should be purchased from a large-scale formal motorcycle shop or engine oil sales store. 2. Engine oil grade: If the summer temperature is not extremely high, 15W-30 engine oil can also be used. Otherwise, 15W-40 engine oil is better. The larger the number after W, the more resistant it is to high temperatures, and the smaller the number before W, the more resistant it is to low temperatures.
I've been riding motorcycles for over a decade, and choosing the right engine oil during scorching summer temperatures is absolutely crucial. I used to use regular oils, but when the weather got hot, I could feel the engine overheating and the noise increasing. Later, a mechanic recommended switching to higher viscosity oils like 10W-40 or 20W-50. These oils maintain their thickness better in high temperatures, reducing friction and protecting the engine from wear. I usually opt for synthetic oils—they're a bit more expensive, but the durability is superior, giving me peace of mind during long summer rides. Also, don’t forget to regularly check the oil level; in hot weather, oil evaporates faster, and running low can lead to problems. My habit is to change the oil every 3,000 kilometers, and I always make sure to get fresh oil before summer hits. Actually, the ideal oil grade varies slightly depending on the bike model—10W-40 is sufficient for city riding, but for mountain roads, a thicker oil is necessary. In short, choosing the right oil extends your bike’s lifespan and makes the ride much smoother.
