What are the precautions for diesel vehicles entering Tibet?

[VanVera]

Avoid the period from December to March. During winter in Tibet, temperatures are low, making it difficult to start diesel engines in cold conditions. If you must go, switch to low-temperature engine oil and diesel with a rating of -20 or -35. Try to choose Sinopec gas stations, as diesel vehicles are most sensitive to poor-quality diesel. The fuel quality at small gas stations in Tibet cannot be guaranteed. Here is additional information: For diesel vehicles entering Tibet, diesel fuel can form wax in low temperatures. If the diesel rating is unsuitable, it can affect the performance of the diesel engine. No. 0 diesel is suitable for use when the ambient temperature is above 0°C, while No. -35 can be used in environments above -35°C. No. -10 is for use above -10°C. Using winter diesel in summer has little impact on the vehicle, but using summer diesel in winter makes it difficult to start. No. -35 diesel is much more expensive than No. 0, but their combustion heat values are essentially the same. Therefore, choosing diesel suitable for the current temperature is crucial.
