VP Racing 28555 Octane Booster Unleaded, Pack of 1

Excellent product. Immediate results after using it in my turbo equipped car. Highly recommend.

The truth it works in a 6.4 Hemi I see it pulling a 35ft trailer I get good gas miles 12mpg that’s why I bought the truck 🛻

Used this in my modified Ford SVT Lightning.Added this to roughly 15 gallons of 93 E10 gasolineI don’t drive this truck every day and sometimes it sits for weeks before I drive it.I figured This would give the fuel a boost.I Could actually feel the power difference which was surprising because I didn’t think it would make much of a difference.The computer must have advanced the timing a bit which is the effect you want from a octane booster.

Not sure if it worked. Did not make fuel smell sweet. Was a great price. Came in a nice protected metal can that did not leak. Shipped really quickly. Functions as directed.

I have a 2013 and a 2004 Jeep I don't run both cars like they should be driven The Jeep sometimes sits for long periods of time and the gas really gets yucky car hard to start.will not stay running have to feather break in gas to keep the car running. I put a bottle of this visit my brother 30 mi each way.Put a bottle of this Top off the tank and on my way back from visiting my brother the car is running perfect again if it's real bad I put two bottles keeps me from having to drop the tank and clean stuff out.Today's gas loses so much burning power that I use this and it just makes life easier I keep a couple bottles of this on the shelf busy life one car sits a long time when I get in the car to run it if it doesn't want to stay running I put a bottle of this like I said and after driving it you know 60 mi car runs better after a full tank of gas my car runs just like it did the day I bought it I bought it used so I didn't buy it new but I love the way my car runs I may know when it comes to everything's got to work on my old car air conditioning everything this stuff is saved me so many times from having to take it to a mechanic and have them flush out the tank

I split this can up for my motorcycle and it runs with substantially more power

My expectations are low for these products, but car ( ecoboost mustang) pulls less timing than 93 octane alone. I can not detect a difference at the strip. Temperature and humidity have larger impact than octane booster. I find it probably helps (.05sec) when hot (Florida summers ), but no difference on colder days. Have not tried it on the dyno.

Great product! This octane boost made a noticeable difference in my 1969 Camaro SS. Very pleased
