Can Yanchang Shell and PetroChina gasoline be mixed?

[DelHannah]

Yanchang Shell gasoline and PetroChina gasoline can be mixed if they have the same octane rating, but cannot be mixed if the octane ratings are different. Yanchang Shell is a joint venture brand, and the gasoline under this brand uses Shell's technology. Mixing gasoline with different octane ratings may have certain effects on the vehicle, such as causing engine combustion or explosion. Refueling precautions: Try not to wait until the fuel warning light comes on before refueling. Because the fuel pump is located inside the fuel tank, it operates at a high temperature continuously, and being immersed in fuel can effectively cool it down. When the fuel warning light comes on, it means the fuel level is already below the fuel pump. If you always wait until the light comes on to refuel, it will shorten the service life of the fuel pump. Having too little fuel or running out of fuel can also burn out the fuel pump. If the vehicle has been driven for more than 30,000 kilometers, extra caution is needed. Once the fuel pump sucks up the sediment at the bottom of the fuel tank, it can easily block the fuel pump or clog the fuel line.
