A good number of retail stores stock fuel and oil additives and advertising for them abound. They pretty much all make the identical claim, that by adding them to your fuel your car will get better gas mileage. The FDA says not one of these products have been approved by them, yet some of them make that claim.
If the FDA has never approved any of these products, why are they permitted to be for sale on the shelves, and say that they have been approved. Who is a person to believe and just what does one do under these instances? If consumers cannot get clear and reliable guidance from an institutional authority, they are vulnerable to false claims. The directions for some of the additives say that you will get improved gas milegae simply by adding the product when you next fill up with gas. Simply because the additive uses up space in the gas tank you will need less gas to fill it up, but you are not going to see an improvement in the gas milegae.
The ingredient list generally contains magnesium, platinum and tin, which are claimed to get rid of any deposits which have accumulated in the tank's bottom. If the product includes acetone, do not use it, since any plastic components in the fuel system may be dissolved. It is reported that acetone in small quantities is safe, but who's to know when that amount is maxed out. It really is pretty risky to test, considering there is no evidence that the product works to begin with. The product could well not do the job, but you could also find yourself with a ruined fuel system. The majority of additives are not going to harm your car in any way, but they are also not really necessary to add to your gas tank.
If a car owner can be made to believe that the product can make his car better, he will buy it, so this is what the marketing boys aim to do. Many consumers are seduced by the advertising claims, and frequently put an additive in along with their fuel. Whether the product actually works like the advertisers claim is hard to check, but so long as people keep buying they have a profitable business. The main reason that these ingredients are superfluous is that the fuel manufacturers already add ingredients that have the same purpose. Fuel additives might not be expensive, but why waste money on them if they don't work the way they promise. If your fuel already does it, why are you being deceived into buying something that doesn't help.
Regarding oil additives, a lot of these only include what is in oil already. What is essential, though, is to use the oil that is suggested for your car. If you use the incorrect grade of motor oil, it may possibly ruin your engine.
