Fuel Injector Cleaners: Any Good ?

They use a flammable detergent, like isopropyl alcohol, to "wash" the injectors. I put it in my Taurus with some premium and it was like night and day, I could spin the tires from first to second if I kept my foot flat.

Who can use that stuff then? I always wondered...

Could a car like a Corvette or Porsche handle it? If not, what about 1/2 CAM II and 1/2 regular premium to bring the octane rating down to about 99-100?

35 years ago, the leaded stuff used to be 102-104 (big block Vettes used 'em).

You sure? You're talking cars pre-1970 then, right? Or early 1970's. Outside of classic cars, not sure there are that many.

Many of todays race cars and kids who think they own race cars are running with no cats. I ran catless on my old truck. LOL
 
There is a company called RC Engineering in California. RC specializes in fuel injectors for all types of applications. They offer an injector cleaning service for like $25 an injector. The only problem is that the injectors have to be removed from the car. They built a custom injector flow bench which measures the injector flow. They measure the flow before and after the cleaning to show you the improvement. The cleaning is accomplished by running a solvent through the injectors and also using ultrasound waves to loosen the deposits. As far as I know this is the absolute best way to clean injectors.
 
pre-73 is without cats... I do believe there is a CAM II that is unleaded, but you would need a car that has a H/O engine and that calls for premium and then use it with a 92/93 unleaded as it would probably burn out your valves at full stregnth
 
One thing to keep in mind guys, the higher the octane, the SLOWER the gas burns. That's why high compression engines use premium-to prevent early ignition (detonation)

Not all FI cleaners are the same. Most do not work as advertised. For over the counter, I would go with Chevron Techron Fuel System Treatment. I personally prefer to use Fuel Power. You can find them from Lube Control Distributors online. It works very well at cleaning the fuel system and making the engine run more efficiently. I add it at every tank or so. I get about a 1 mpg increase.

For once a Oil Change Interval (OCI) cleaning, I like Schaeffer's Nuetra. I would add it to the tank and use it up before I change my oil. That way, any insolubles that make it into the oil are drained out.

And you thought an obsession with wax was bad...:D

Scott,
Have you been hanging out at Bob is the oil guy again.

I like Techron for an OTC FI cleaner.

Lucas makes good stuff and you can also use Marvel Mystery Oil ...that stuff is great in everything...fuel, oil, tranny, etc...

Marvel Mystery Oil is a subsidiary of Turtle Wax, If I'm not mistaken.

Has anyone used any of the "OMG!! My car's like new!!" stuff advertised on tv, like Slick 50, Duralube, ProLong etc.?
 
UPDATE: I couldn't find the Chevron or Red Line or Lucas stuff, so I went with some STP FI/Line cleaner stuff. Just poured it into the gas tank and then had it filled (nearly filled).

I'll check out some of the premium auto stores for those other products you guys mentioned. Thanks a bunch, guys.

BTW...I saw "Octane Boosters" which were made by STP, something with "104" on it, and they all said OK for most engines, use 1 bottle per full gas tank, etc.

Do these things do anything if you don't have engine ping or is it just another waste? Can a regular car utilize these things -- alot different adding these 12-16 ounce products to 12-20 gallons of gas than filling up a gas tank with 106+ octane stuff, right?
