How to solve the problem of Yamaha Xunying burning engine oil? What should I do with the new car?

If your cylinder is not strained and worn badly, you can only replace a pair of piston rings and valve oil seals to eliminate the problem of burning oil. I suggest you change it as soon as possible. Burning engine oil will consume more gasoline, and spark plugs will easily break down. You don't have to put oil when changing piston rings, and it's not a big problem to delay for a while. But you need to check whether there is oil at any time. A car that burns a lot of engine oil burns a bottle of engine oil in less than a month. Is it a new car? In fact, you have already said that this remedy is only to change the cylinder piston. Of course, there will be more money. If it's not a new car or an old car, I suggest adding more oil, something good. Don't be short of engine oil to avoid danger. Check the oil for a while, and if it is less, add more.
