so i recently seen the gumout one and done post and its cleaning ability. that got me thinking what if i were to use say techron for 3 tanks in a row? i dont have any problems with the car just curious if any good could come from it?
Not gonna do jack, even if you run just straight additive with no fuel. Lol. Been proven in YouTube videos that there's no difference before / after. Waste of money.
The right kinds of cleaners are only good for injectors and when sprayed across valves in port injection/throttle body injection, in my opinion they do nothing else in effective amounts when it comes to combustion chambers.
Best way is to insert the cleaner into the fuel rail and disabling the fuel pump. I never had a lot of faith adding a half pint of cleaner to a near empty tank of several gallons. You would be better running a top tier fuel instead.
