South A, If it works for you great, I am just commenting that no and I mean no major oil company, engine manufacturer nor industry/government group recognizes the effectiveness of these additives. As for the waste water comparison... Have no heard of this. Typically dispersion is a bad thing ... the objective is clean water. Usually flocculants are added to remove solids, then... Many waste water systems do use microbiological ponds/tanks to lower COD and BOD. This is quite different in many ways from what we are discussing. The critters in this ponds actually feed on the hydrocarbons etc. These are aqueous system that are extremely sensitive to rapid changes in temperature, chemistry etc. These are not enzymes but living microbes who happen to fancy the crap in waste water for dinner. The one place where I know dispersion is used is for oil spills. Basically the chemistry (not an enzyme) breaks the oil up creating more surface area for the oil- eating microbes to dine. The microbes live in the water. In conclusion not an expert on waste water systems but have seen a few in the oil patch. The enzymes may work but as pointed out here and other threads ensymes are typical denatured in hyrocarbons any comparison with an aqueous system is a big stretch. Anyway good luck and excuse the long replies.

Mickey, All good points, Yep, since the government mandate on detergents in gasoline, Techron and one or two other additives dominate the market. Gasoline detergent pgkes went from a marketing tool to a commodity. Interesting is Shell's latest campaign. As for the mystery oil. A lot of aftermarket suppliers were adding phosphorus to alleviate valve recession, following the banning of lead. The adverse affects on catalytic converters pretty much eliminated their use in autos. This was how valvetech started. Engine manufactures solved the problem by hardening the valve seats. The alcohol debate is another long story, just depends on how much water, get enough water, alcohol dissolves in the water layer, minor amounts of water.... alcohol will help keep the system dry by dispersing the water in the fuel. The PTFE was added to some extent to help increase MPG. Lighter oils were the end result...5W's

Tim, I stand corrected, Been doing some work on the upstream side where demusifiers are used to drop the water. Chemistry same just adjustment of crosslinking, monomer ratio's and polmer MW... I should have read more closely before I hit the reply button. Thanks for pointing this out.

ok let me ramble ....more so than my last post. First let's remember that the fuels today are dramatically different from just a few years ago. Specifically sulfer phosperus, aromatic and heavy ends content are much much lower. Secondly the engines have changed compression ratios, carbereration/throttle body injection to direct injection, O2 sesensers and in the case of autos catalytic convertors. And last ,most of these changes have been driven by enivormental regulations Also all engine testing is done with fresh fuel with properly tuned engines. First point.....comparisons of yesterday... ahh simpler times are interesting but not relavent. Fuel degrades but not as much as most of us think. But fuel stabilisers do work and are antioxidants ,several types are used. Necessary, maybe your call, I don't. Remember point one above, modern fuels in a clean system are stable. I usually have 50 to 100 gals in my tanks over the winter no problems. I do change my filters and inspect. No issues. Professional point of view most re-labelers don't have enough active to make a difference, oil company products and engine manufature's products are effect if dosed as directed Disspesants.. see string on this forum "chemists" Detergents are very similar to dispersants and as discussed above products from the Major oil companys work and performance is supported by research. As a back drop all gasolie sold in the US is reguired to have a detergent. This was a result of performance issues with newer engines were valve deposits were developing followed by combustion chamber deposits. Do you need...well witnessing a lot of the testing this is truly a game to barely pass the test. So for me I add nothing to my small merc my cars but to my yammi 250's (2-cycles) I add ringfree. This is recommended in the owners manual. Making a difference. Can't prove but... I know the stuff works (well documented) and cheap insurance. I burn a lot of fuel. As for the lawn ower story.. same result could be acheived by using an aromatic solvent point being most of this products will work question is at wat dosage. Spay some gunk down the carberator Lubricity additives. Since the advent of cleaner fuels premature wear problems were noted on high pressure fuel pumps soecifically on deisal systems and jet engine pumps. This is a result of the almost complete removal of sulfer which provides good lubricity. Lubricity additives today are dimer trimer acids. Oil and such don't provide protection for this type of metal on metal wear. Besides in a car you will plug the cat converter and as with an outboard screw up the o2 senser. In conclusion same as before, the additive packges discussed here and else where, that are sold by re-labelers might warrant close inspection. I am not going to bash. But being in the fuel and lube business for many years.. I do not use this stuff. However i have and do use major oil and engine manufactures products if needed. This is true for all my cars,boats etc. Ok done sorry for the long post

Not much of a poster but have to comment on this. I have posted on THT on similar threads. First I have been involved in the oil and fuel additives business for 20+ years working for one of the largest supplies of fuel and lube additives. In this capacity I have been involved with all the the major oil company formulations and have represented my company at many of the tech societies SAE, API, NMMA, ETC. Specifically i was involved with the formulation of the additve pkg that is used in 70% of all 2-cycle oil sold in the USA. I have reviewed hundreds of engine tear downs and thousands of lab analysis. So to answer the original question, First i am not aware of what's in this specific additive pkg. There are thousands of these aftermarket pkgs. in the marine, auto and diesel markets. But, from my experience most provide a lot of claims but little performance. Not knowing the exact formulation but based on experience the chemical will rapidly mix into the fuel. No problems. As for the physicist above... enzymes are protein oligomers and are denatured in hydrocarbon. His claim as to how this additive works is interesting. This was discussed before in these forum. But hey go for it. I never heard of such talk in any industry forum. Typically a demusifier is used to accomplish the above.. This chemical will disperse the water and sludge into the fuel where it is carried into the combustion chamber where it is burned or in the case of water vaporized. This works fine except if you use too much additive or you have a lot of water or sludge . you may clog the filters. Most of the reputable additives reveal this and recommend paying close attention to filters and changing often until the system is clean. My experience, you want an additive buy from an engine supplier or a major oil company. They do the testing and can back up the claims. The experience i have with the aftermarket suppliers and believe me I have dealt with many is they take a very unlikely test result and greatly and I mean greatly exaggerate the performance. Some things to look for... performance claims linked to very specific dosage recommendations and most of all does it pass the smell test ; that is you can't turn a pigs ear into a silk purse.

I'm not much of a poster but in this case thought I would add.... I have bought about $6K from RMS since hurricane Ike and another $2 to 3 K prior. All transactions have been positive. I had a windlass shipped to the shop that was outfitting my boat, the breaker was damaged they replaced no questions, Another time I ordered 3 sets of outriggers accidentally,,(must of been the whiskey) end of the week all three showed up, mailed 2 back no problem. I'm in Texas so have no knowledge of the thefts except from the stories on THT.
