Best and most cost effective product of its type,

Short version:

Among all fuel system cleaners I am aware of, Redline SI 1 holds the highest quantity per dollar based on maker MSDS of the important fuel system cleaning compounds called polyether amines PEA. Mainly 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 hasn’t been needed to use Redline’s suggested quantity of roughly three oz per fill up. The effects of one oz per fill up are indistinguishable by tested results see my base for this declaration below. This results in an estimated cost of $0.35/tank or less than a 10th of a penny per mile. A full case at this handling rate is enough to treat 180 full tanks of fuel or to last roughly 80,000 miles. Figures established 15gal/tank, 25 35mpg.

Long version:

As far as I know, every efficient fuel system cleaner on the market uses a class of compounds called polyether amines PEA, in varying proportions, to effectively clean deposits from fuel system parts, and especially from fuel injectors, which can quickly affect engine efficiency and performance when not operating properly. My understanding is that these compounds were 1st developed by Chevron and sold under the Techron name, and have since been made available to other blenders of fuel treatment merchandise. Till newly BG 44K, Chevron Techron Concentrate, Gumout Regane Fuel System Cleaner, Amsoil P.I. Performance Improver Concentrate, and Redline SI 1 among others listed polyether amines on their Material Safety Data Sheets MSDS in proportions varying from roughly 25 to 50. Most of these merchandise not list PEA on their MSDS, having changed their terminology to disguise the exact nature of their products’ constituent parts. If PEA is still contained in those merchandise is a matter of doubt. As of this writing Redline’s SI 1 MSDS still specifies that the product holds 30 50 PEA. Consequently it’s one of the not many left over fuel system cleaner merchandise that undoubtedly does contain PEA in important quantity.

I have been able to test the effectiveness of fuel system cleaners in one of my own vehicles using a technique I stumbled on after having its injectors professionally cleaned while out of the car. The car in question uses a Bosch engine management system that reports fuel injector data to an on board computer, which then uses that data to compute and report instant and average mpg to the driver. I noted after the professional cleaning that the accuracy of the stated mpg, when used to measure average mpg over each full tank of fuel, improved from a previous error of around 3 5 that is, the stated mpg was 3 5 below the real mpg, or usually just over 1mpg low to an error as close to zero as I could measure that is, typically between 1 and 1, fluctuating above and below a perfect “match”. This may be clarified on the base that the engine management system will reimburse for a dirty injector by holding the injectors open somewhat longer throughout each combustion cycle, to admit the correct total of fuel. The on board computer interprets that as a somewhat higher rate of fuel intake, reporting a lower than actual mpg figure.

After some number of thousand miles not long the perfect mpg accuracy I’d noticed started to deteriorate, probably showing that the cleaned injectors beginned to suffer from many sort of renewed blockage to fuel flow. Out of a want to keep near perfect injector performance, and also out of curiosity, I started experimenting with different commercially available fuel system cleaners and keeping records of the results at each fill up.

Leaving out the long details, I will simply say here that the results were amazingly clear and unambiguous. Every time I went some number of tanks without using a fuel system cleaner usually consequently of simply forgetting to use it or not taking the trouble, the on board computer OBC accuracy could deteriorate. This could change from tank to tank, of course, consequently of inevitable measurement errors, but the trend was clear over a few fill ups. Returning to the use of a fuel system cleaner Chevron Techron Concentrate, Gumout Regane or SI 1, all of which at the time did contain PEA, the accuracy could improve again quickly inside 2 3 fill ups. I began using the SI 1 entirely seven months ago depending on its obvious cost effectiveness and since then I reduced the quantity I use in each tank to the current 1oz per 15gal fill up. The results remain unambiguous. If I use this small total of SI 1 steadily, the accuracy of the on board computer is excellent, with an average error of below 1, or a small percentage the error rate seen when not using such a product.

Based on the above I feel I can confidently complete that SI 1 works well, at reduced treatment rates, at keeping fuel injectors clean. Fuel system types and injectors will differ, and other parts of the fuel system as an example intake valves and combustion chambers may gain from higher treatment rates or, conceivably, may not benefit at all. Real engine efficiency won’t differ almost as much as injector hygiene, since the engine feedback system usually corrects for imperfect injector flow rates. But, as the flow is more largely impeded, or impeded differentially among the individual injectors, mpg will be influenced to many degree. I feel it’s well worth the tiny cost to steadily use a small quantity of SI 1. Other benefits, like to combustion efficiency consequently of combustion chamber hygiene, to volumetric efficiency consequently of intake valve hygiene, and to fuel system lubrication, most likely exist also though I can’t evaluate them and haven’t attempted to do so. Other fuel system cleaners may work as effectively, or almost as effectively, but I don’t believe them to be as good by value per dollar spent.

In my experimentation I did attempt many less costly fuel system cleaners, those not containing PEA. They appeared to dont have effect. I can’t categorically state that only PEA containing fuel system cleaners work, of course, but my observations did match the regular wisdom on this point. I also experimented with using top tier fuels only, without any extra fuel system cleaners. The results were the same as when using non detergent Costco and others fuels. I do not doubt that top tier fuels contain small amounts of cleaners and will keep a fuel system functionally and acceptably clean, but the amounts involved are reputed to be tiny and my observations seem to point to that a small total of extra additive is far more efficient.
