This one dual-cavity bottle contains the same number of additives equal to a bottle of regular fuel injector cleaner, upper cylinder lubricant, fuel stabilizer, anti-gel, diesel treatment and cetane booster. Talk about the perfect all-in-one! It also increases power, performance and mileage and saves fuel by cleaning and lubricating the entire fuel system.
