Qinghai oil changed to gas, who changed red oil to gas? Did you change it well? What is the motivation?

It has been more than five years since my car changed from red oil to gasoline. Toyota's car has been used steadily, and the power is good, saving a lot of money. The qualification of red oil is on the right track and the procedures are quick. Recently, I went to check the gas cylinders from red oil to gas, and all the products were updated to imported kits. The price is cheaper than any one in Xining. It's really a good product. I'm going to get a new car and change it. The service is good. I hope I can give it to you after sale.
