Fuel additive, which brand is easy to use?

Red line, Chevron special gold, little red bottle G 17.

These three are excellent fuel additives in the industry, and the use of the red line needs to be repackaged by users themselves, one at a time. Especially strong is the use of large bottles for 5000 kilometers, and the small red bottle G 17 uses one bottle for every two or three boxes of oil. The first two are powerful, and the latter is mild, which means that your car is old, you haven't used fuel treasure much, and there are a lot of carbon deposits, so it is more appropriate to clean up stubborn carbon deposits with special power at one time. If you are a new car and have no carbon deposit, the effect of G 17 is milder.
