Great preventative maintenance
The cost on these buying them 12 at a time is the best I've seen around. I've been using this fuel injector cleaner over 20 years on my personal vehicles adding the appropriate amount to treat the # of gallons the fuel system holds (larger vehicles require 2 bottles to treat, read the directions for details) at 3,000-4,000 miles and I've had great success. No fuel system issues to date. Would I have had issues without using the injector cleaner? Maybe, maybe not, but for the cost I think this is cheap insurance. I also use these in small engines. My 15 year old push mower that gets about 100 hours of use every summer is still on the original carburetor and my 13 year old motorcycle hasn't had any issues. I'd recommend using the cleaner, and no I'm not being paid to say this 😂

A must have for all your Rides
I have been using this STP Fuel Injector Cleaner for close to 30 years. We use it in all of our cars, suv, truck and moms cars. We add a bottle every 4th of 5 fill up. We have never had a fuel related problem with any of our vehicles. The 12 pack on here is the best price I have found for it. Well worth the price and pretty much a must have maintenance item for today's fuel injected engines.

Great Value! Great Product!
I'd been buying this product 1 or 2 bottles at a time from a local store. For what I spend on this 12-pack, I saved quite a bit. As for the product itself, I purchased my '19 Explorer Sport (used of course w/100k miles) earlier this year and she seemed... temperamental? LOL I've been using this product regularly at fill-ups & she's a lot happier now.

Did not work for me
Waste of money. No changes in Jeeps behavior using these. Also checked the injectors and so significant difference.

Does the job
Been using this stuff for over 25 years and I have never had to get my injectors cleaned. I use 1 everytime I change the oil.
