#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.
#14 of 1246 100 Octane... by adc100 Jul 13, 2001 (8:20 am)
The higher the octane the slower the burn is in the cylinder. People using higher octane than needed are simply throwing their money away. I wish they could throw some my way. The only time you should use it is if your car is "knocking" And then you should get that looked at because your timing may be out of spec. High octane could in fact cause more carbon in your car and less power because it could burn after the optimum time for it to deliver it's max power. Oh well, the gas companies need the extra cash.

"iondustrial" Injector cleaner:   I'll have to check the label...I buy it from my friend who runs a Porsche repair shop and he usually dumps it in for me because I don't even want to be near it (he doesn't either, but he's careful). But I had a bad injector acting up on my Benz diesel and it fixed the problem completely in about 25 miles.
#17 of 1246 Cleaners ... by brorjace Jul 14, 2001 (3:44 am)
As has been said before, MOST of the cleaners a fuel system needs are already included in the gasoline. BUT, we all get a tank or two of bad gasoline once in a while so using a couple bottles of an injector cleaner each year isn't a bad idea. It's cheap insurance. Just be sure to use a good one.   Chevron Techron is good but over-use of this stuff can foul your engine oil. Chevron recommends this stuff be used a couple weeks before your next oil change just to be safe.   I've had great results with Redline SI-1. I gave a third of a bottle to my buddy whose throttle-body-injected 1981 VW Rabbit was getting a miserable 24mpg and in one tankful, he was back over 30mpg. Zoinks!   Just beware of all the glitzy junk out there. Putting mediocre cleaners or cheap alcohols in a flashy bottle and charging $5-10 seems to be a fad these days. Don't buy into it!   I also like to use a little isopropyl alcohol now and then to keep my fuel system moisture free. Just be sure to avoid anything with "methanol" in it. That stuff is so corrosive, it shouldn't even be on the shelves anymore!   --- Bror Jace Replies to this message: sonix (Oct 11, 2006 8:40 am) shipo (Oct 11, 2006 8:59 am) beancountant (Oct 12, 2006 8:46 am) highroller (Oct 12, 2006 9:53 pm)

For what it's worth: I've been using STP Concentrated fuel injector cleaner for the last 10 years at every oil change (3K miles) on new Ford cars and trucks and have not had any clogged injectors nor any fuel system problems. Maybe it works--maybe it doesn't, but it hasn't caused any problems at all.

Step #2 does nothing to clean your injectors. It is introduced to your engine through a vacuum source and only cleans the oooey gooey stuff from the crankcase that gets inside of the intake manifold via the PCV valve; it also cleans the combustion chambers, catalytic converter, and oxygen sensor. Fuel goes through injectors, not air, therefore the intake cleaner doesn't pass through the injectors at all. The stuff they add to the tank of gas is what is supposed to clean the injectors. How do I know this? I work at Jiffy Lube now, unfortunately.
