Dilution ratio's on the in-tank stuff are so high, that I don't think they do much.   Maybe use some Chevron Techron, but the highly concentrated fuel-rail type 3m stuff undoubtedly works a heck of alot better for removing deposits from injectors and backs of intake valves
#6 of 1246 Do fuel additives help keep an engine clean? by trifivenomad Sep 25, 2001 (7:29 pm)
#7 of 1246 I add Chevron Techron fuel system cleaner... by trifivenomad Jul 12, 2001 (9:46 am)
to my gas tank every 3000 miles, but I'm not sure if it needs to be done so often. Does anyone know if fuel additives really keep intake valves and injectors clean?   Is good quality gas enough?
#8 of 1246 Well -- by mrdetailer Jul 12, 2001 (3:24 pm)
The same additives are already put in gasoline.   The oil companies also say nothing more is needed.   Some of those same companies also sell gasoline additives.   Those pictures of cleaned up engines seem too good to be true.   FTC sued companies for oil additives not living up to representations.   Didn't sue any Gasoline Additive companies. Most made both oil and Gas Additives.   Fuel injection repairs are expensive.   Additives are cheap.   I personally use them. I also do a 3 stage fuel injector cleaner every 15,000 miles. I had a car that needed premium until I got the big treatment. Now it uses regular.   I like them. Replies to this message: gashauler (Mar 31, 2006 10:25 am)

I'm very dubious about over-the-counter additives you buy at 7-11. Personally, I only trust industrial grade additives that take off skin and paint and cause birds to drop out of trees when you open the top. They aren't easy to find and they are expensive, but they work.   I think most off the shelf additives are harmless and just duplicate (if that) additives already in your fuel.
#10 of 1246 How about racing gasoline? by trifivenomad Jul 13, 2001 (3:49 am)
A local Texaco station sells 110 octane Union 76 racing gasoline. Of course it's for "off-road" use only.   A friend told me that this gasoline gets its high octane rating from nitro-methane. Is that true?   If a couple of gallons of this gasoline happen to get into my Chevy, will it clean the intake valves or will it damage the engine? It costs $3.50 a gallon. It sounds expensive, but it's alot less than $6.00 for a bottle of Techron concentrate, if it works.
#11 of 1246 More questions... by trifivenomad Jul 13, 2001 (5:48 am)
mrdetailer,   What is a 3 stage fuel injector cleaner and how does it work?   Mr. Shifty,   Who sells the industrial grade additives? Which brand do you use? Replies to this message: keepemttd (Aug 20, 2005 11:03 pm)

Techron injector cleaner seems to make an improvement. I add a bottle at each oil change.
#13 of 1246 3 step process for fuel injection. by mrdetailer Jul 13, 2001 (7:55 am)
This is done by professionals. I have had my mechanics to it for $100.00, and Jiffy Lube for about $40.00. They seem to perform about the same. This is done at the same time as the oil is changed.   1. A cleaner is put into the oil. 2. A large bottle is added to the fuel injection system through the vacuum hose while the engine is running. 3. Another bottle is placed in the gas tank.   Stage 2 is obviously some serious stuff. The workers use gloves safety glasses, and a fume mask when they put it in the bottle. As it runs into the vacuum hose it really stinks while it is cleaning out the carbon. I did 2 this year. One was bad and the bottle was almost gone before the carbon smell went away. The other smelled much better about half way through.   On the car that was bad, I had to use premium gas for a smooth ride, even though I get a tuneup yearly. After the treatment it has been running great on regular.
