Engine treatment products?

Has anyone used these type of products that you put straight into your petrol tank and it surpossidly cleans the engine, chambers etc etc improving performance, fuel economy etc etc.

Do they work?

Are there better ones than others?

Are they just a con?

Thanks in advance.

    To be honest with you a lot of the engine additives that you can purchase to clean out your engine only work if they are truly required.

    For example there is not point in trying to clean out carbon build up in a cylinder head if there is not carbon in the first place.

    The best way to clean out an engine is to take the car every few weeks fr a nice long high speed drive.

    Ja.

    Hello Laurie, it makes me so mad when people give out bad information... Don't put anything in your fuel tank except fuel, same thing for the engine oiling system, nothing but oil. When an engine is burning oil or making odd noises it's a sign that the engine needs repair, there are no additives that will replace the rubber on worn seals or repair steel on worn piston rings. The additive you put in the tank did more harm then good, it made the oil seals swell up and now you have leaks in the front and back of the engine, the only way to repair this is by removing the engine and replacing the seals. When an engine becomes worn with age everything wears out together and carbon builds up keeping the engine sealed, once that carbon is removed by an engine flush there is nothing to keep those voids and rings sealed so it starts to leak oil, shady companies take anvantage of people like you and promote products that supposedly reverse the effects that it took 100,000 and 3 years miles to create, ain't gonna happen. If this was a friend of your's i would kindly tell them they ruined your engine by giving advice on a bad product and know they will pay the repair bill to replace the front and rear main seals, if this was an auto parts store i would kindly tell them they gave you bad advice which caused harm to the engine, you can't sue them because you're the one that poured it in but you can surely hurt their business by slandering them in front of every person that goes there..... I wish i could get to every person before they are conned into wasting money on an junk additive that did nothing but harm. Oil goes in the engine and fuel goes in the tank, the only product i will endorse is Lucas oil treatment because it modifies the oil and increases lurication properties or Stabil which goes in the fuel tank and prevents it from turning to varnish or becoming stale

    If you mean things like Redex/Wynns/STP, then don't bother. The oil companies like Shell/BP/Esso etc all put additives in the fuel anyway, so they're just a waste of money.

    If you feel your car has lost some performance and it's not just needing a service, it's possible to get the fuel injectors professionally cleaned, which can make a big difference, it's not dear- £20-ish per injector and some workshops can do it while you wait.

    Putting something in your fuel tank to clean out the entire engine simply isn't going to happen. You're not going to un-gunk your motor by simply having a fluid pass through your injectors.

    If you really want to clean all of the built up residue and crap out of your engine, you'll need a product called "seafoam" my friends and I swear by it and many mechanics do as well. It's simply a petrolium product which breaks down built up sludge in the engine and then has your car poop it out through the exhaust in the form of blue smoke.

    Take one can of seafoam and dump it straight into the gas tank to clean out the injectors. Then, take a half can, unhook your brake booster line, and, with the engine running, slowly funnel it in there and shut the motor off quickly, suspending the fluid in the heads long enough for it to break down the residue. Start your car back up and take it for a spirited drive and you'll be amazed at how much carbon buildup you can wave bye bye to.

    If a person properly maintains their car by doing oil and filter changes, fuel filter changes and such...they should not have any need for these items. No, they do not do as they claim. The main attraction is that they are priced just cheap enough to attract buyers. They promise all kinds of things but don't deliver. Nobody uses the "money back guarantee" many offer because of the stipulations required for the refund.

    I swear by Techron, too. But the best is to use Mobil gas everytime, it keeps everything cleaner and prolongs oil changes because the oil stays cleaner longer. Also, if you want the best MPG's and performance, install a set of Bosch Platinum or Iridium plugs. They react with the fuel chemically to optimize combustion.

    Fuel system cleaners do actually work... if you need them. Most gasoline sold today already has detergents in it, so they do a good job of keeping your engine clean all on thier own.

    Now the additives you put in your oil are another story. Those are mostly rubbish.

    im a 16+ year technician,and i have NEVER seen anything you dump in oil or gas do anything at all except cost money.when stuff is worn out...its worn out there are no miracle fixes..only band aids.in fact no auto manufacturer i know of recommends putting anything in your engine other than the specified fluids.hope this helps.
