Cheap Red Line SI-1 Fuel System Cleaner - 15 oz. (Case 12 Bottles)BUY IN A CASE AND SAVE On Sale
Short version:
Among all the fuel system cleaners are aware, Redline SI-1 contains the highest amount per dollar (according to manufacturer safety data sheet) compounds critical fuel cleaning system known as polyether amines (PEA). Primarily for this reason I believe that SI-1 to be the best available and cheaper fuel system cleaner products at a retail price. At the current price per bottle when bought by the case right here at Amazon ($ 5.30) is a bargain (15/12/2009 edit: the pricehere has almost doubled since I wrote this and it is now, unfortunately, anything but a bargain).
In my case it was not necessary to use the recommended amount Redline about 3 ounces per fill-up. The effects of 1 oz per fill-up are indistinguishable in terms of proven results (see my basis of this statement below). This translates into an approximate cost of $ 0.35/tank or less than a tenth of a cent per mile. A case in full at this rate of use is sufficient to treat 180 tanks full ofor fuel to last about 80,000 miles. (Figures based 15gal/tank, 25-35mpg).
Long version:
To my knowledge, any fuel system cleaner effective on the market use a class of compounds known as polyether amines (PEA), in varying proportions, to effectively clean deposits from fuel system components, particularly from fuel injectors, which can quickly impact engine efficiency and performance when not working properly. My understanding is that thesecompounds have been developed and sold under the name Chevron Techron, and have since been made available to blenders of other products for the treatment of fuel. BG 44K Until recently, Chevron Techron Concentrate, Gumout Regan Fuel System Cleaner, Amsoil PI Performance Improver Concentrate and Redline SI-1 (among others), polyether amines listed on their material safety data sheets (MSDS) in proportions ranging from about 25% to 50%. Most of these products no longer on their list PEA MSDS,have changed their terminology to disguise the exact nature of the fundamental components of their products'. PEA is still contained in those products is a matter of uncertainty. As of this writing Redline's SI-1 MSDS still specifies that the product contains 30-50% PEA. Consequently, one of the few remaining fuel system cleaner products is undoubtedly contain PEA in significant quantities.
I was able to test the effectiveness of fuel system cleanliness in one of myvehicles using a method that, after stumbling on a professional clean your injectors from the vehicle while outside. The car in question uses a Bosch engine management system, which contains data on fuel injectors, an onboard computer, which then uses the data to calculate and report instantaneous and average mpg to the driver. I noticed after professional cleaning that the accuracy of reported mpg when used to measure average mpg on every tank of fuel, sudden improvement from a previouserror of about 3% - 5% (that is, the mpg was located ~ 3-5% below the actual mpg, or generally just over 1mpg low) for an error close to zero as I could be measured (ie, usually between -1% and 1%, hovering above and below a perfect "match"). This can be explained by the fact that the engine management system to compensate for a dirty injector holding the injectors open slightly longer during each combustion cycle, so as to permit the proper amount of fuel. The on-boardcomputer interprets a rate slightly higher fuel consumption, a key figure mpg lower than real.
After thousands of miles - not long - the exact mpg perfect I had noticed began to deteriorate, probably indicating that the injectors cleaned began to suffer from a kind of renewed fuel flow impedance. The desire to maintain performance injector almost perfect, and even out of curiosity, I started experimenting with various commercially available fuelcleaning system and recorded at each fill-up.
Omitting the details at length, I'll just say here that the results were astonishingly clear and unambiguous. Each time I went several pools without the use of a cleaner fuel system (usually a result of simple forgetfulness to use it or not take the trouble), the onboard computer (OBC) precision deteriorate. This swing from tank to tank, of course, due to unavoidable measurement errors, buttrend was very clear even on a small number of fill-ups. Returning to the use of a fuel system cleaner (Chevron Techron Concentrate, Gumout Regan or SI-1, which at the time did not contain PEA), the accuracy would improve again very quickly - within 2-3 Fill-up . 've Begun to use the SI-1 only seven months ago on the basis of its apparent cost effectiveness and I have reduced the quantity used in each tank to 1 ounce of power to fill up ~ 15gal. Since the results are unequivocal. IfI use this small amount of CA-1 consistently, the accuracy of the onboard computer is excellent, with an average error below 1%, or a fraction of the error rate is not displayed when you use such a product.
Based on the above I feel I can safely conclude that CA-1 works very well, even at a reduced rate of treatment, to keep fuel injectors clean. types of fuel system and injectors varies, and in other parts of the fuel system - for example, intake valves and combustion chamber - couldbenefit from treatment rates higher (or, potentially, could not benefit at all). actual performance of the engine will not vary nearly as much as injector cleaning, as the motor feedback system usually corrects for imperfect injector flow rates. However, since the flow is more strongly hindered or prevented in differentiated between individual injectors, mpg will be affected to some extent. I think that is worth the small cost to consistently use a small amount of CA-1. Other benefits, such ascombustion efficiency as a result of cleaning the combustion chamber, the volumetric efficiency as a result of cleaning the intake valve and fuel system lubrication, probably exist as well, although I can not assess and have not attempted to do so. Other detergent supply system can work as effectively or almost as effectively, but I do not believe it to be as good in terms of value for every dollar spent.
In my experiment tried a bit 'cheaper detergent supply system,those that do not contain PEA. They seemed to have no effect. I can not categorically state that only a pea, containing the fuel system cleaners work, sure, but my comments gave the conventional wisdom on this point. I also experimented with the use of fuels of high-level only, without any further cleaning the fuel system. The results were the same when using non-detergent ([...]) fuels. I have no doubt that the top tier fuels contain small amounts of detergents and maintain a system of functional foodsand acceptably clean, but the quantities are known to be very small and my observations seem to indicate that even a small amount of additional additive is far more effective.
