I used this specific product and although I did see a difference in performance, the car has excessive diesel consumption that it didn't have before with the obd2 diesel chip. I have been driving the car for two years and I didn't have such high fuel consumption

My car, after refueling with diesel, would turn off. Poor quality fuel. I used this specific product while emptying and replacing the old fuel with a little new one. Not only did the car work, but it didn't turn off again
