Berryman chemtool fuel system question

[67wtc]

Just a curious question. On various posts I've noticed some people talk about this product and how it does a good job cleaning. How was your engine running before you used it and how much of an improvement did it make for you? Did you try other products before this? I've tried some other products for the fuel system and nothing seems to make a difference. I'm thinking about trying this but I was looking for opinion/testimonials first. Thanks

It was recommended to me by my mechanic.....I had a "misfire" on several cylinders.
I have had this come up several times.....in spite of using a fuel system additive in a "maintenance" dose.....Redline and FP60 are the 2 that I have used in maintenance dose.
Most fuel system cleaners are detergent based......and the 2 that I list above are as well.
I have used others....and like you, found that they did nothing to smooth out my engine.
I once spent months trying to track down a slight miss......and once it got bad enough to light the CEL and have a code......I pulled the fuel injector for that cylinder......and that is what I posted in my pictures.....the crud that builds up inside the "end cap" ......right at the spray end of the fuel injector.

Since that time, I have corrected the misfire, when it has happened, with the Berryman's B-12 Chemtool.
I think that it is a good idea to treat the fuel, say 2 times a year.
The Windstar seems to have an issue with building up junk inside that end cap at the fuel injector output.
I have tried adding a catch can to reduce the amount of oil vapor that enters the intake.....while still keeping the PCV system doing it's job of pulling junk out of the crankcase.
Even with that, and a maintenance dose of a detergent cleaner / lubricant to the fuel system, I find that the Berryman's a couple times a year helps.

Simply put.....I know that it works.

What it will not do, is clean the IMR plates or EGR ports, as the cleaner is in the fuel......and those 2 items are not in the fuel path.....so the cleaner never touches them.

Thanks for your input Wiswind. I'll see if I can find it around my area.

They carry it at AutoZone......and I'm sure that it is carried may other places as well.

Advance Auto Parts has it and I get it in a Walmart (Plattsburg NY location) too.
