Fuel Additives

Hello guys and gals. I get asked by a lot of my friends if fuel additives really do anything to help your car. So today we're going to be going over some of the fuel additives that I think work and some that I think are complete snake oil.
There are a lot of different additives out there, but some of the biggest cons are products like octane booster. That is the one of the products I have the most hatred for. They claim to boost the octane level of your gas and they convince you that it will boost it by a large percent. In reality the marketing boys just sold you on a product that may only raise the octane rating by .001. The only products that I have found that work are all simply detergents. There are three that I use frequently.
The first one is a fuel additive called RxP. It's usually at the front counter of parts stores and is about $7 a bottle. What it is, is an engine decarbonizer. That means it cleans the carbon out of anywhere fuel goes, mainly in the combustion chamber. This is great for routine use in older cars which have a lot of carbon buildup from all the little explosions in the cylinders over however many thousands of miles. All of the cars, that run, at my house have this on their last tanks before an oil change simply because they're pretty clean and I don't want old carbon floating around in the oil.
The second one is a similar product RxP. This product is Chevron fuel treatment and says Techron right across the label. It's a bigger bottle than RxP and It's practically the same stuff but it might be a little more diluted per ounce. Think of it as putting almost 5 bottles of RxP in your tank but you get about the same result as putting one in. It actually costs about $1 more than RxP. Personally, I like RxP better but it's completely up to you which one you get. Each seems to work about as well as the other.
The last one I'm going to talk about is my personal favorite. It's called Sea Foam. Most people have heard about it by now and if not, YouTube search it. When I say it's a fuel additive I mean it can be used as one. Most times it works the best if you take the vacuum line of the brake booster and let it atomize in there. It deep cleans all the crap out of your engine and when you start it you see it working. Most of it is water which makes it steam up and look like you just blew every valve seat and piston ring when you're going down the road. Every time I use it the car runs way better. I highly recommend Sea Foam.
Be careful what you put in your tank. These three products are great but many are just cons and will either do nothing and make you burn money or potentially do damage to your engine over time.
