Customer Review
Best and most cost-effective product of its type
Short version:Among all fuel system cleaners I'm aware of, Redline SI-1 contains the highest quantity per dollar (based on manufacturer MSDS) of the critical fuel-system-cleaning compounds known as polyether amines (PEA). Primarily for this reason I believe SI-1 to be the best available and most cost-effective fuel system cleaner product at retail pricing. [...].In my case it has not been necessary to use Redline's recommended quantity of approximately 3 oz per fill-up. The effects of 1 oz per fill-up are indistinguishable in terms of tested results (see my basis for this statement below). This results in an approximate cost of $0.35/tank or less than a tenth of a penny per mile. A full case at this usage rate is enough to treat 180 full tanks of fuel or to last approximately 80,000 miles. (Figures based 15gal/tank, 25-35mpg).Long version:As far as I know, every effective fuel system cleaner on the market uses a class of compounds known...

Raised my gas mileage 3-4 points
My '06 Civic SI has about 40,000 miles on it. It had been getting around 22 mpg (mostly city driving) but even with long distance freeway driving (around 75mph) I'd only get about 23 mpg. I usually use Chevron or Shell gas. I also have used Techron fuel cleaner in the past with no results.So I used Red Line SI-1 a few tanks ago, and my gas mileage has increased to about 26 mpg for my last few tanks. Right now I'm at 318 miles on one tank of gas, and i have one bar left on my fuel gauge (it's digital). Prior to the Red Line the best I'd ever gotten was 312 on one tank of gas, and that was after driving the ENTIRE tank on the freeway, and driving 10 miles with no bars left on the fuel gauge. Typically I would get 250-270 miles on one tank.I'm stoked!I will admit that using this stuff ain't going to do anything to help you if your injectors aren't clogged... but if you suspect they are, this is the fuel cleaner to get!

I Trust It
I belong to an online forum of Colorado owners (coloradofans.com) and created a poll to see which fuel system cleaner the members liked best. This one did very well, so I tried it and I like the results. I have poured a bottle in the tank prior to every oil change recently.I also like Techron, because it seems to give me a smoother idle over each tank of gas. Redline seems to bring out the raw power of my engine though.I am not a mechanic, but it seems to work for me.
