What kind of engine oil should be used for the Jiangling Yuhu diesel version?
2 Answers
Jiangling Yuhu diesel version uses Mobil Jiangling 5W40 engine oil. The following is extended information: 1. 5W40: The number before W represents low-temperature resistance performance, with 0W, 5W, and 10W. The larger the number, the worse the low-temperature resistance, and 0W has the strongest low-temperature resistance. The number after W represents viscosity, which is high-temperature resistance performance, with 20, 30, and 40. The larger the number, the higher the viscosity. Choose the appropriate viscosity based on factors such as vehicle model, mileage, driving habits, etc. Higher viscosity is not necessarily better. 2. Replacement cycle: If it is mineral oil, it is generally replaced every six months or about 5,000 kilometers. If semi-synthetic oil is used, it is replaced every 7-8 months or about 7,500 kilometers. For full synthetic oil, it is replaced every year or about 10,000 kilometers.
The Jiangling Yuhu diesel version is the model I frequently drive. For diesel engines, choosing the right oil is particularly crucial. Based on my experience, the official manual generally recommends using API CJ-4 grade diesel-specific oil, with a viscosity like SAE 15W-40 being quite common. When driving in northern winters, I switch to 10W-30 to adapt to low temperatures, then switch back to 15W-40 in summer. In terms of brands, I've used Shell Rimula or Mobil Delvac, which are affordable and offer good protection. Diesel engine oil must withstand high temperatures and resist carbon buildup, as diesel engines have high emissions. Using the wrong gasoline engine oil can easily cause piston seizure. I stick to checking the oil every 6,000 kilometers or so, which helps prevent performance degradation due to oil deterioration. In short, referring to the manual and selecting the right specifications ensures a smoother and more worry-free driving experience.
