I started using the MMO on my Acura integra since there was carbon deposit when looked through the spark plug hole. After about a 32oz (80gals of gas), gas mileage improvement was noticed only during the last two application (overall about 6%). I was recommended to continue to use the MMO.
Techron is good. I’ve had success removing carbon (and grease and paint when soaking parts) with Berryman products. Seems to be pretty potent, fast acting stuff. I’ve used their carb cleaner, no experience with this total fuel system cleaner.
Home Depot has reviews . And how hard is it to drive to Home Depot or a local place that sells that product. Why make things difficult ? The Gumout stuff will not harm anything so why not try it and see if it helps ?
“High Energy Solvent Technology,” a Berryman exclusive, incorporates the use of strong solvents, as opposed to weak carriers and dilutes such as mineral spirits or kerosene”
I assume the MMO has the dilutes in it that they’re referring to. As does Seafoam. As does the Berryman stuff to some extent, I’d imagine. Some are weaker than others, but who knows which. You might experiment with some different brands over a few tanks and do a non scientific test.
Good catch. I updated my reply.
Sorry I misread the op. No it won’t get into the intake manifold. But it will get into the piston/cylinder. I don’t deals with these things on a daily basis so my vocab got rusty.
For engines with injectors upstream of the valves, every 30k miles or so. I have one car with direct inject known to carbon up the valves bought used at 30K. I did that car when I bought it. I think I’ll do it again 12K later.
Right, what I meant - in the video they are injecting the seafoam directly into the intake. It’s not getting diluted with 15 gallons of fuel like it does when you pour it in the tank (like you did the MMO). Straight into the intake is a quicker, more aggressive way of doing it than mixing it with the gas in the tank.
