Redline SL1
This contains the highest concentration of cleaning agent pea polyethelenamine. More than chevron techron and more than gunk with pea. If it doesn't have pea it is snake oil. The carbon will come out of your combustion chamber and mix into the motor oil so use in a tank right before changing your oil. Your oil will be dirtier which is good it means its doi g its job. This is the only effective fuel system cleaner. Ive spoken to engineers at Redline, gunk, chevron and royal purple. If you can't afford this use gunk with pea it will say it on bottle. Every car should have a clean fuel system. I use 1 bottle for 15 gallons of gasoline. About 1 oz per gallon right before changing my oil. With valvoline full synthetic 5w30 high mileage and either wix Baldwin , Hastings or k&n oil filter. This product is for real. You'll be glad you used it. 10 stars

Costly but seems to work
I can say this I will never allow my truck to go below a half a tank of fuel, I put this treatment in around 3/4 a tank and haven't let it run out or close to 1/2 tank without adding more fuel. Next time I purchase this, and there will definitely be a next time, I'm going to wait for a long trip and really run my motor. As it is now I only live 5 miles away from my job so 10 miles a day round trip I don't think is giving this a fair judgement. But the reviews I've read where very good! So I bought it. End of story.Read full review

Catalytic converter saver
B4 you go spending up the wazoo to have it replaced .... reset the check engine light with a $20 code analyzer..,...run one tank of quality detergent premium with one bottle of Redline. It may clean out your cat and save you $. Worth a try.Read full review

It's the best stuff out there.
I put in half a bottle in 10 gallons of gas and burned it out before changing the oil. I noticed an improvement about halfway through the terms of acceleration. Just before the next oil change, I'll put in the other half of the bottle. It's best to do it that way so that any sludge nastiness is taken out with the old oil.Read full review

I can feel and hear the extra power in my Motorcycle.
I mixed up 5 gallons of this stuff and started using it on my motorcycle and my lawnmower. After the second tank in my motorcycle I was hearing and feeling the improvement. I don't know if it helped the lawnmower or not.. It is a lawnmower after all. It just makes a lot of noise and cuts grass..
Good stuff.Read full review

My choice for fuel system cleaner
I guess it is doing it's job. After I had the plugs and coil changed,
the car is running o.k. now. I will continue using Redline .
