3.0 out of 5 stars No MPG Gain for me, July 6, 2011
Verified Purchase(What's this?)
This review is from: Red Line (60103) Complete SI-1 Fuel System Cleaner - 15 Ounce (Automotive)
I bought this because of its high percentage of concentrated detergent ingredient. I get my gas from a gas station where Top Tier 100% pure gasoline is sold.
Maybe I did not need an extra fuel treatment but for peace of mind I used it.

From among Redline products I also use D4 ATF.

I have yet to do more MPG per tank calculations but the first calculation showed me that Redline fuel treatment has not added any MPG. With the treatment I got the exact same mileage I used to get without it. All other conditions being equal.

I bought another bottle to try on our van. I hope to be able to get better mileage with it there.

Even if I do not get higher MPG, I would not regret using it as a great cleaner. We do not even know now if Chevron Techron fuel treatment includes that specific detergent or not. No mention of it in the product data sheet.

Does anyone know what 'pollution control valve' is in a car? Because here and on redline website it says 'Cleans pollution control valves'. As far as I know there is no such thing in any vehicle. If they mean PCV-positive crankcase valve, even then this is problematic since no cleaning can revive a dead PCV. It needs to be replaced and in many applications the price of replacing it is a few dollars at most. Anyone knows what redline and amazon mean by 'cleaning pollution control valves' ?

Perhaps it is talking about the egr (exhaust gas recirculation) valve?

If it is EGR valve, then it is a great accomplishment, by just adding this in gas tank.

Modern vehicles have a valve (sometimes called evaporative purge valve) related to the fuel tank itself. It keeps gas tank fumes from escaping into the atmosphere. This is what Redline is referring to.

They do mean your PCV valve and EGR port.
Of course it can't replace a dead PCV valve, just like it won't unclog a completely clogged injector or fuel pump.

Your skepticism should be how can this fuel additive get to the PCV valve considering that is on the other side of the combustion chamber?
Apparently there is supposed to be enough dilution that some of it will slip past your piston rings and into your crankcase, which then will remove some of the deposits on your PCV valve same as it does your injectors.

paragraph on cleans emissions controls

This should lead you to the consideration that this means there is some redline diluting your oil's chemistry. So you should consider timing this treatment (and all fuel injector treatments) a few fillups prior to an oil change
