An good recommendation for Injector Cleaner Fuel Additive?
40,000 mile '94...

RetroGuy

Some here on this forum would say to fill up with premium octane Chevron gas with Techron, or add one of these every 3 or 4,000 miles. I don't believe the bottle which states every 1,000 miles.

Some will say that additives are snake oil, others will swear by them.

I like to put SeaFoam through my system as it creates billowing smoke from the exhaust. The smoke pisses my neighbor off. I don't like my neighbor. I like SeaFoam for that reason alone.

If anything, Techron, but in general I do not use them.

Check the MSDS sheet for these various additives and you will be surprised at what they contain.

Naptha, Xylene, Toluene (lacquer thinner), Isopropanol (Isopropyl alcohol), Benzene, Acetone etc

If you have Multec injectors, anything will do. Double the dosage. Repeat a couple time and the new injectors you get will be clean and ethanol resistant. Everybody wins. Except your wallet, that is. IF you have Multecs, I'd dump them for a set of "reman" ones from FIC that have already been serviced. If I get a job by one of the additive makers, that will be the best one to get.

I use gas from any frequented station and send them off for cleaning and testing if they are anything but Multecs. I get the money from the savings from buying the snake oils to know that they are clean.

I use Lucas and my 94 starts in a half a crank. Is is smoothas silk at 34,000.

I don't use Lucas and my '92 starts in a half a crank. Is is smoothas silk at 184,000.


I have a great recommendation; how about NONE? The gas you buy already has injector cleaner in it. What problem are you trying to fix, that the plain old gas you're buying isn't already taking care of?

GOOD READ & PICS HERE

I use Lucas. Techron is good too. You shouldn't really need it, but a few ounces in 18 gallons isn't going to hurt anything. I bought my '90 for $2K because one of the injectors stuck open, hydro-locked the engine, and threw a rod through the oil pan. A little insurance is a good thing.

aklim

Of they were Multecs it probably helps to eat away at the windings. Same with ethanol. I doubt you will have enough build up in one to stick it open or the other 7 would be in the same boat.

jv9999

They were the Bosch 700 series yellow tops. When I got the car two of them were stuck open. E10 dissolves everything. What the filter doesn't catch ends up in the injectors.

aklim

I think there's a filter in the injectors themselves. If E10 dissolves the substance it would be sprayed out or what happens to it? It probably is the varnish from sitting. I have no way of knowing what the additives really do, if anything more than draining my wallet in exchange for a good feeling. I do know what periodic cleaning will really do based on the flow bench reading

The Techron or Lucas additives are about the best out there and are mentioned all over the Forum.

Use the best high test gas in your area and a station that has a lot of traffic. Keep your tank above half and you will not scavange any garbage in the gas. When i see a car for sale on line with a tank in reserve i will not buy that car for all that pump in the tank is doing is picking up debrie . The stand alone fuel filter can not get every item passing threw, some of this stuff is as small as a microm

aklim

Too bad none of the mentions include a test from an accredited laboratory using standard testing methods for critique and instead rely on marketing to create a hype.

aklim

I think we went through but never got to know how you did it. How did you modify the tank so it sucks only the top fuel and prevent sloshing that stirs up debris? My pump picks up from the bottom. Is your tank different? How much debris is there in the tank when you drop it? Also, you have 3 filters. Sock, can and injector filter.

Tom400CFI

^^ Right?^^.


You don't need "high test" either. The cheapest gas you can buy is mandated by the EPA to have the necessary detergent in it...and it works. Did anyone look at the pics I posted in my linked thread? Fake? Did you? I buy gas from my grocery store, for the most part. Cheapest gas I can find. Go back and look at the pics.

Guys, this falls into the category of "Worryin' about **** that ain't worth worryin' about". Do good PM on your car, run it and everything will be fine. No elixirs needed.

The techron is quite literally the detergent package added to gas at Chevron stations. (Well an approximation anyway) It may be of a higher grade than your run of the mill additive package but again, like tom said, the cheapest crap is still more than enough for anything but the "most exotic cars."*sarcasm* (Top tier does exist for a reason I suppose... and even still that probably doesn't mean much. How the heck does Costco have that cert?) The only thing I know for a fact that it does work with is those crap level senders on the 98-03 gm fuel pumps that corroded with the ethanol. I'm 70% sure GM actually released a TSB on it and to use it to make the senders read again under warranty. It worked for me... until I replaced the crap pump a couple weeks later.

I'll sure as **** try the products and see if I can gather real world results. I drive the same route every day and have 3 years of mpg averages to back up the claims of all these additives. Long story short, they all fell into the standard deviation of my data meaning they made not a difference. I've also played around with fuel grades too to no noticable difference except the company bill statement being higher. Basically my data shows there isn't magic power to be had in some potion* and if you have a problem, don't bandaid it. Fix the problem. You're just pissing money in the tank hoping for a fix. Eventually you'll surpass what it cost to fix it in the first place.

*Having first hand experience with restore I can say it does actually do what it is proclaimed to. Brought up a bum cylinder on the blazer to a reasonable number. Also, running marvel mystery oil in my tank somehow did improve mpg outside of the std dev once... but only once and thus something else may have caused it.

Not trying to argue, just saying my experience. I also run wawa gas in my vette and daily. It is the cheapest I can get my hands on and the station is like a mile from my house... and they're all over.

all I know is that the gas in the state of Ohio is considered bad and I havebeen using Lucas in all of my car's sincethe sixties and never had any problems. Just saying

Also have had great luck with adding Rislone oil treatment and never had a engine problem in 48 years in any of my vehicles.
