I wonder if it fouls up sensors faster than pre-e10 days? Due to the need of the added detergents and cleaners concocted for the ethanol blended gas.
That said, how is it known how any 1 cleaner can damage a sensor or converter? SeaFoam claims safe with 02 sensors and helps 'clean' the cat to reduce the 'rotten eggs' smell. Maybe carburetors, but cats.? I'm just glad they'd say it won't damage those parts...but is it really a guarantee they are held to or just an advertising scheme?
My dad claims they used to use Tranny fluid at times in the old carburetor fuel systems, but mainly back in his day growing up(70s). Wonder how that would work on fuel-injected fuel systems or what the potential draw backs would be for using that in your fuel line.
Amsoil PI is about ten times stronger than Techron and is supposed to clean carbon and, more important, gas fouling from injector spray on intake valves as well as cleaning the injectors.
That said; I used it half a dozen times and usually used a pint of water a couple times a year.
When I did the valve job at 350,000 miles there was some carbon on the pistons.
Amsoil told me to use PI with every fill-up. For me that is a treatment every day or two.
Leads to the question of if any gas treatment is worth the money.....especially since all gas stations have detergent in all of their gasolines.
I use and talk about, but don't sell Amsoil.

I wonder if its necessary to run water occasionally anymore. Ethanol blended fuel will absorb water from the air, so in the normal course of driving you should have some amount of steam in the cylinders which may help keep valves clean.
