Great gas treatment
Put one in with a full tank and so far it has worked great as my truck seemed to be wanting to die on me at stop light, now it is going fine.

5 out of 5 stars review
Made a few noticeable differences
[This review was collected as part of a promotion.] Small bottle but it made a difference. I don't know a lot about cars but I noticed a little over 1 mpg improvement on my gas mileage. I would get maybe 12.8 mpg before adding this treatment and now up to 14.1. I haven't changed my driving at all so it has to be the treatment. I noticed my rpm's show a little higher and steadier (if that means anything) . Also my truck sounds better when idled. I will be getting this on a regular basis. Would recommend. FYI my truck has 163k miles.
