Buick Hideo's throttle is noisy.

It is true that Yinglang's engine is noisy. Mine is a manual XT of model 20 10 1.6, and the pick-up time is September 20 10. The engine noise of Yinglang is obvious at low speed. When the speed exceeds 80, it will become quieter and quieter. When it exceeds 120, the engine noise will increase. As for the valve noise you mentioned,

The engine noise of all cars is getting louder and louder, which is similar to that of Volkswagen. At least my engine noise for two years is slightly lighter than my friend's Ming Rui for three years, and Bora for four years is obviously louder, so this is misleading.

Fuel consumption, it is suggested that this car should use better engine oil from the beginning, and the maintenance of private cars 1 year will only be two or three times, so it won't cost a few dollars to use a fully synthetic car, because the fully synthetic car has low fuel consumption and low noise, which is good for engine protection. In fact, my car has been maintained in a shop in 4S for two years, using a fully synthetic gray shell, so the fuel consumption has not increased so far. The increase in fuel consumption is generally related to the condition and maintenance of the vehicle, and has little to do with the quality of the engine itself.
