Somewhat disappointed
GEORGE FERNANDEZ✓ Verified Purchase•July 20, 2023
Everything about the product is reasonable however. What looked like one of the bottles leaked all over the inside of package as one bottle was completely empty not sure of some of the other bottles as a few of them felt a little empty!
STP Fuel Injector Cleaner, Works in my Honda Pilot --July 2021--
Caracy✓ Verified Purchase•July 4, 2023
I bought these to see if they would help my Honda Pilot. I gotta say, I noticed about a 10 % increase in mileage. Nothing scientific here, just more miles on the odometer before I needed gas. Really noticed it on a long trip. Anyway, I think its helping and I've bought them again.
My thinking on products like these is this: If your engine is clean -either new or well maintained- you may not notice any significant improvement. Like putting clean dishes in the dish washer. There's no difference but it doesn't mean the dish washer isn't working.
If your engine is of average use -like apparently mine was- then this helps clean out whatever unwanted gunk is in there and helps your engine run a little better.
If your engine is really bad, then when this stuff cleans it out, well, that gunk has to go somewhere. It gets burned up with the gas and your car may actually run worse until it clears it all out. These are the only scenarios I can think of that would explain why some people swear BY this stuff and others swear AT it!
I know its a generalization and of course there are varying degrees of quality and additives from brand to brand, but I think its a pretty fair summary.
Also, I add some to my 2 cycle fuel mixes for my string trimmer, snow blower etc. They're not fuel injected but they have all those small ports and needle valves and such that I think products like these can also help keep clean.

Tiny bottles

I bought these at a brick and mortar store and they were way bigger. These are super skinny and not as much content. Why is that? I guess it works?
fine

SHOULD DO 2 TIMES A YEAR
The Real Deal.

I use this gas treatment when I get to around a 1/4 tank, pour in a bottle and then drive about 10 miles and then fill up the tank to at least 1/2 full or more and can definitely feel my wife's car idle and run smoother, I use it around 2 to 3 times a year, definitely recommend
