Octane Boost Race Fuel Concentrate - 16 OZ - Boosts Octane Levels Up to 8 Points - Cleans Engine, Enhances Performance, and Stabilizes Fuel - Octane Booster - Racing Fuel

Came in good condition

I added this bottle to my gas tank 16oz to 20 gallons gasoline to improve fuel economy. I noticed very minimal increase in fuel economy, less than 0.5 mile per gallon increase. I understand the solution was diluted over the recommended dilution percentage but there should have been a more significant increase in fuel economy. Before: 18.5mpg/ After: 18.8mpg

It's very difficult to provide a meaningful review of this type of product. Overall, I felt that it gave a little extra "pep" to my cars and motorcycles, but that could have been a placebo effect. It hasn't harmed anything, and everything is still running fine, so I suspect that it's safe to use in your vehicle. I'm hoping that it'll help to clean the fuel systems, but again, how do you know without tearing down your system (something I'm not willing to do at this time).For the price, you receive a pretty large bottle that claims to be highly concentrated, so in that regard it's a good deal... However, mine arrived leaking inside a plastic bag.. and given that this type of product is HIGHLY flammable, that's not a good deal. Deducting one star for packaging.Overall - recommended due to the perceived "pep" from boosted octane.

Full disclosure: I used part of this can in my 4Runner and part of it in one of my Harley's. My hope wasn't to increase the performance, but rather to clean out the injectors. The 4Runner had only about 8 gallons of gas, and the Harley tank had about 5 gallons.The results from the 4Runner are still unknown because I've driven it very little in the past month, so the jury is still out. However, the Harley definitely did show improved performance after only burning through about one gallon. It has a "Screamin' Eagle" engine, which is Harley's performance engine, so the improved throttle response is very noticeable.If I had any complaint, it was simply getting the can open! The cap unscrews with no problem, but the metal insert into the top of the can was difficult to remove. I had to stick a pick in it to create a hole and pry it off. Thankfully it didn't create a spark! Otherwise, I'm completely happy with the results I've seen so far.

I've done a lot of upgrades to my truck and have to run high octane this wasn't a bad deal. Works for on the go with a decent gain. Perfect for a cheaper fix than buying race fuel and mixing your own additive.

I like that this product does add some extra pep to my step. My car is turbo charged and even though it says it’s not street legal I used it on my street legal car and I could notice an improvement with my idle and acceleration. It wasn’t anything major so don’t expect this to make your car feel like you added a nitros kit. It adds just a tad more power for immediate acceleration and when at a dead stop definitely helps smooth out the idle. I’m looking forward to this helping my gas stay fresh for a while since I don’t drive my car as often. Overall I think this is a good product to have for people with turbo charged cars that might not drive as much and want to ensure that every start is a good start with fresh fuel.

Earlier today, I emptied the entire contents of the bottle into my Ford F150 Lariat Supercrew 4WD with the 5.4 V8 and K&N Air Intake System... I had about 25 gallons remaining in the tank. Then I decided to take it on a “quick” spin around the block. (We live in the country where around the block is about four miles.)My main purpose in ordering this is to use as a fuel system cleaner... and have a little fun seeing if it would boost performance. The engine did seem like it had a just a little extra kick. I plan to drive it until the tank is almost empty before refilling to hopefully loosen and blow out any gunk that has accumulated.

Added A Small Amount , During Each Fill Up To My Jeep Grand Cherokee , Increased Engine Power, And Better Fuel Consumption - Improved Efficiency & Clean Injectors .
