(6 pack) 104+ (10406) Octane Boost, 16 oz

I received this product at no charge in return for an honest review. I used the product in a tank of gas in my truck just prior to towing a 12 foot trailer full of furniture. I use 87 octane unleaded in my high mileage truck and typically get some knocking during acceleration, particularly when towing. I towed the full trailer about 200 miles and never experienced any knocking. In fact, the truck seemed to accelerate stronger and more smoothly with the 104+ Octane Boost added to the tank of gas. Not sure I would use daily, but for towing and other harder driving it makes a difference in performance and even gas mileage. [This review was collected as part of a promotion.]

I decided to give 104+ Octane Boost a try in my '03 Land Rover Discovery. Anytime I run premium gas in it, it always seems to get better mileage. I normally see a slight improvement with 93 octane pump gas, I was hoping to see a more noticeable improvement with the 104+ Octane Boost. With nearly 3/4 of the treated tank used, I can say with certainty that I'm seeing a gain in excess of 3mpg. That's almost 65 extra miles with a full tank used. I also noticed less hesitation in the throttle response. Overall, the improved mileage and smoother running engine make 104+ Octane Boost a winner with me.

I have been using Gold Eagle 104 Octane Boost for a few years now. The first time that I used it I was travelling to a car show in West Virginia. I was towing a trailer and needed all the help that my car could get to climb the mountains. My car had no trouble after adding the 104 Octane Boost and my gas mileage improved also. I love this stuff and use it frequently. [This review was collected as part of a promotion.]

Out of the three products I have reviewed this is the most difficult. I drive a 2009 Dodge Challenger SRT8 ( 6.1 L) and run a 93 octane gasoline in it. After adding the 104+ Octane Boost I found it very difficult to notice any difference in performance or gas mileage improvement. I'm confident that there was probably some but it just wasn't noticeable to me. Having said this, I still rated the product with 4 of 5 stars because of the other benefits it is supposed to provide ( clean injectors, remove gasoline deposits and provide an anti friction barrier to the piston walls). Again this is something difficult to evaluate however I believe in the " quality of products" that Gold Eagle provides based on my experience with their other products and this is a claim that they make. These benefits, as stated, are difficult to evaluate and may or may not be realized after only one full tank of gas so I will continue to use the product. In retrospect another test that I could have done would have been to reduce the octane level I purchase ( say to 87) and see if the addition of 104+ at least maintained the car's performance but I didn't think of this until later. If this works it would negate the additional cost of the 104+and you would receive the additional benefits of injector cleaner, remove gasoline deposits and provision of a friction barrier!!!

I just received the Octane Booster and decided to use it in my truck. Unless I use top grade premium unleaded gas, my truck will "ping" and pre-detonate. I used the octane booster and had no pinging and it seemed like a lot more power. Using this product saved me about $7.50 by not having to buy premium unleaded gas.
