(12 pack) Super Tech Fuel Injector Cleaner Automotive Additive, 6 fl oz

I have been using the Super Tech Fuel Injector cleaner for years. It is a good value and our vehicles seem to start better and have better performance (mpg) when it is in the gas tank. There is never been a problem with smoke when using the cleaner.

Pretty simple. After filling my my car's fuel tank. I used the product, which the design is of the product is awesome. No mess. Took my car on the freeway for a few miles at 70 mph. And noticed my engine was running smoothly with a bit more power. Good Stuff for such a small price 👍

I add fuel injector cleaner in my cars' gasoline tank twice a year at minimum plus use SuperTech Fuel Injector in my lawn mower and snow blower each season to keep the carburetors clean. The cars are over 10-years old and the engines run well. The thin neck bottle's shape makes it easy to pour into the gasoline tank.

I use it quite frequently. Can not tell if it does anything. But with today's gas I and for a small fee it costs, I use it.

Like I said in my other reviews of super tech products, this is just as good as the big brands. I don't know why people buy the name brands when these work just as good for a fraction of the price.

I add a bottle every few months just in case

Increases my miles per gallon

Treats up to 21 gallons of gas. I use a bottle, now and then, when I fill up my Honda's tank. Tank capacity is only 14 gallons, so it's a bit "rich" in the ratio to fuel. Sometimes I buy cheap fuel but, typically, I use Shell gas. I've recently noticed my car like Chevron fuel, so I'm going to use it more often.

Not sure if it did anything or not.
