Review on 🔥 Revitalize Your Fuel System with Red Line's Complete SI-1 Fuel System Cleaner - Gas and Injector Additive Treatment (12 Pack Case) by Sfl Richardson

If you buy gas from any gas station other than Chevron or Shell, this product is a must. Gasoline is exactly the same at all gas stations, but they have different levels of detergents, which keep the fuel system and engine clean. Use the bottle twice a year just before an oil change. This fuel additive has the highest percentage of polyester amine based detergent on the market. Do not try other products. I've heard that some people only use 1-2 oz (from a 15 oz bottle) on each tank of fuel and get even better results. $26 for two bottles a year isn't a lot considering it could save you hundreds of dollars on repairs down the road.
