ive seen a lot of fuel treatment additives on the shelfs.I want to know what is a good one to use on a chevy 350! i know i have to use the ones for carbs and i know quite a bit about fuel additives, but i want to know which is the best one for a chevy 350. I want to keep the build up off of my pistons and values, to keep the engine running smooth. It runs good right now, but i want to keep it that way! please give me some names and if possible, prices! Thanks a lot-)
Good question, the best fuel additive on the market and has been for nearly 70 years is Marvel Mystery Oil fuel additiveget it at any auto parts store for about $3.50 roughly a bottlethoroughly cleans fuel injectors, valves, fuel system and removes water and impurities from your gasolinewill keep your car/truck idling smoothI have been using it since 1961.(Marvel has been in business since the 1940s)******
Bad module. Depending on the make and model this could be the single most expensive part on the car excluding the engine and transmission. You could try to have the system flushed but I doubt that would help.
