What type of oil should be used for the Boyue 1.8T?
3 Answers
For the Geely Boyue 1.8T model, it is recommended to use 5W-40 semi-synthetic oil for maintenance. Below is an introduction to semi-synthetic oil: 1. Semi-synthetic oil is made from semi-synthetic base oil, which is lubricating oil formulated from international Group III base oil. It is a product refined from mineral oil through hydro-cracking technology. 2. Semi-synthetic oil is a mixture of mineral oil and full synthetic oil in a 4:6 ratio. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than that of mineral oil; it is an ideal transitional product from mineral oil to synthetic oil. 3. Full synthetic oil contains 100% non-traditional, high-performance fluids. Semi-synthetic oil contains a smaller percentage of such high-performance fluids and includes traditional mineral oil.
As a long-time automotive enthusiast, I believe when selecting engine oil for the Borui 1.8T engine, Geely officially recommends using full synthetic oil, typically with a viscosity between 5W-40 or 5W-30. The exact specification should be confirmed in the owner's manual. The advantage of full synthetic oil is that it provides efficient high-temperature protection, preventing wear on turbocharged components and carbon deposit formation. It's recommended to use brands meeting API SN or SP standards such as Mobil or Shell to ensure smooth engine operation. The oil change interval is best set at every 7,500 kilometers, but this can be shortened if frequently driving in stop-and-go traffic or high-temperature conditions. Remember not to use mineral oil or mix viscosities, as this may reduce engine lifespan. Long-term neglect of oil selection can lead to decreased fuel economy and increased maintenance costs. In summary, regular maintenance can prolong the overall health of the vehicle.
I am an actual user of the Geely Boyue 1.8T and have been driving this car for several years. I always use Castrol Edge 5W-40 full synthetic oil, which has been very reliable. The manual recommends either 5W-30 or 5W-40 depending on the regional climate. Since summers here are hot, I opt for the thicker 5W-40 for better protection. The oil must be full synthetic; otherwise, the turbocharger can easily get damaged. Once, I tried to save money by using conventional oil, and the car became noticeably noisier—I immediately switched back. Brands like Mobil and Shell are also good, but the key is to buy from official channels. I stick to an oil change interval of every six months or 7,000 kilometers, and I always check the air filter at the same time. Neglecting oil changes can lead to unstable idling or carbon buildup issues. Make it a habit to check the dipstick before driving to avoid unnecessary trouble.
