"Great additive" 2010-01-02
By M. Masztal (Melbourne Beach, FL)
I started using fuel injector cleaners back in the early 80's. A new Volvo 242 I had purchased new was starting to perform sluggishly. Another owner recommended a f..i cleaner which I tried and it worked pretty well. Over the past 28 years I've tried just about every fuel injection/system cleaner on the market. Some worked well, others didn't. The Red Line SI-1 works better than the others I've tried. My vehicle ran smoother, acceleration improved and I saw about a 2 mpg improvement. I have to add that the BG44K cleaner works very well too, but at three times the cost.

This is one of the best fuel system cleaner on the market. It was first introduced to me by my machanic. I have been using it for over 3 years and still using it. vehicle runs much smoother after apply one bottle of 15 ounce SI-1. I apply one bottle every month. It sure makes difference. I have been telling my friends about this product and they all agreed that this product is currently the best.

In my honest opinion and based on over a decade of direct experience:
Redline is the single best upper cylinder lubricant, as well as the best cleaning agent for the entire fuel system of your auto that you can buy.
Loaded with system cleaning amines it tops other name brands in overall effectiveness while remaining entirely safe for use in all automobiles.
The best price anywhere for this outstanding product can be had on Amazon.
That is all... :-)
"Best fuel cleaner available. " 2009-02-25
By R. Shelton (North Carolina)
Red Line's fuel system cleaner has got to be the best on the market. I have tried just about everything and have been using Red Line for several years with near perfect results. I don't follow the directions, however, as I add the bottle to 1/4 of a tank of gas and run it until the fuel light comes on. This can cause the vehicle to run a little rough but it's worth it! As a side note, if you need this you probably could stand to replace your oxygen sensor(s.) The combination can yield a substantial increase in fuel economy and driveability.
"The best fuel system cleaner - period" 2009-02-09
By Nutty Prof. (chicago, IL)
People not into racing don't know that Red line has been making racing oils for about 30 years. They have the best chemists and the best manufacturing techniques. With gas prices on the rise and the possibilty of contaminants in the gas we buy - this is cheap insurance. You cannot depend on even the most expensive gas to contain cleaners. I used to buy Shell thinking they had me covered. I got clogged injectors anyway (twice). Now I by gas from Costco or any discount place and add the cleaner myself. The bottle is marked in 10 gal increments so if you have a 34 gal tank just add 3 10 gal marks from the bottle by pouring a little at a time until you get there. You do this before you fill up so it mixes as you add the fuel. Your vehicle will run smoother than it did when it was new after a few tankfulls. The price is the cheapest I have seen for this product. Pep Boys was selling this for nearly $9. This is the best investment you can make to your fuel injected vehicle. I don't what effect this will have on carbs so if you have an older car try one from a retail store first.
