The best fuel injector cleaner

[Moveitsmikey]

What 'facts'?

I use absolutely NONE of that stuff and fix my own cars, no one else ever touches them once I buy one and 3 or 4 cars running at all times for some 40 years now.

Ingredients in the product. It has all the right stuff.

Mikey, I suppose some people are curious as to why these ingredients would be considered the right stuff... for a fuel system that the manufacturer says should not run any additives, just gasoline.

If you are using a good grade of fuel you have all the cleaners you'll ever need.................it's been federal law for centuries.

Ingredients don't mean spit if you don't know what the percentages are..............most of those sold are fuel in some wildly distorted form, they have most 'of the ingredients'. I sold maintenance chemicals for a good while and I never saw any solid proof out of any brand and some really longterm customers.........UNTIL............you start thinking of the DRIVER as the improvement you want. Of course, part of the sales training is to push the customer hard with the prerequisite bullsh-t, you stroke their ego bigtime to get that sale.

Improves fuel mileage an average of 2.3% and up to 5.7%
Reduced emissions
hydrocarbons (HC) up to 15%
carbon monoxide (CO) up to 26%
nitrous oxides (NOx) up to 17%

Straight from the website they do rigorous testing on all their products. This is probably more of a benefit for vehicles that run 87 octane. I run top their fuel and only 91 so I dont really need the product. But it is great. Helps reduce deposits and clean intake valves and combustion chamber.

Just a thought. 400 miles per tank and 2.3% of 400 is 9.2 miles. So I bet if u just put 1 qt gas in instead of 1qt cleaner u would get 5 miles extra. So spending money for an extra 4.2 miles. Let’s see that less than 1qt gas or about .65cents ?

Yeah that makes sense. Though no fuel injector cleaner will dramatically effect gas mileage. If you have s*** gas mileage a tune up is your best bet.

Wanted some opinions about this: useful or overpriced service?

Just got my oil changed today and the service advisor reviewed the "Items requiring attention soon" portion of the inspection report: They recommended the Complete Fuel & Induction Service, to the tune of $319.95.

Is this going to do a better job than me pulling off the throttle bodies, cleaning them and trying to clean as much as I can in the intake manifold that I can reach without taking it completely apart as well as running some Redline SI-1 through the engine?

I had the induction service performed at my local dealer about a year ago in Dayton, OH and it cost $180. I had it done at 20k miles. I did not notice any improvements, but on the way home I did hear and feel a loud clunk in the engine upon acceleration onto the highway. I think a big chunk must have broke loose and ultimately got tangled up in my catylictic converter. Two weeks later I pulled the intake and inspected the intake valves, they were covered in deposits. Some were dry and crusty and others were gooey (probably from the induction cleaning). It took me about 8 hours to get the job done but I'm slow at this kind of stuff. I do not recommend any fuel injector cleaners be used in this engine if you run good gas in your car. The cleaners would never make it to the intake valves because if the direct injection. I think that a good solution to this problem would be to remove the intake and modify it to have some ports above each of the 16 intake valves that can be closed off with a screw. Then every 5k miles or so you could just remove the engine cover and spray down the dirty valves one at a time. The way the intake is shaped you are very unlikely to effectively get any cleaners to the valves by spraying anything in through the throttle bodies or brake booster vacuum line.
