(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.

Increases my miles per gallon

I have use this for years

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.

Ordered Lucas fuel treatment and this is what was in my bag when I received them
