Not STP, but good!
I drive a Suburban which has quiet a few miles on it, over 200,000.
This may not work as good or as quickly as the name brands, but it is inexpensive and therefore you can afford to use it more often. I have had only good results. When I use it often, I can see and feel a difference in the engine and mileage.
I won't go back to the name brands!

Smoother engine
I drive at least 450 miles per week in an older, 200k + mileage car and never fill the tank without a bottle of SMB Super Gas Treatment. The engine runs noticeably smoother and I get good, steady gas mileage. I do use quality gas most of the time, but in a pinch off-brand gas works just fine when I use this treatment as well. It is easy to dispense, and does not leave a bad odor on my hands.

subpar....
I liked the old AUTOGUARD brand that Dollar Tree sold previously....this new stuff contains "ethanol" it says right on the bottle....which is kind of odd....now I did do some limited research, and was told "ethanol" is a good detergent/cleaner.....but it tends to slump the MPG.....in fact all of the "SMB" fuel treatments had the same notice about the ethanol.
I actually found when I cut the bottle/dosing in half, I got a tad better MPG though....best bet would be the manufacturer to remove the ethanol....my guess is they are using ethanol as the disperment agent.....when they should be using kerosene, similar to other additives....but then again, ethanol is probably "cheaper" than kerosene right now with gas prices going up....lol.
