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!!!

Octane 104 is to boost the octane level of gasoline. So I did an experiment by using this product in my 2005 BMW which requires 91 octane fuel. I added 104 before I filled up the tank with 87 octane gasoline. I assumed that this product would increase the octane level to 91. I checked my fuel economy after I burned through the tank and found that my MPG was less than comparing it to using 91 octane fuel. I concluded that this does not give enough of an octane boost to replace the use of 91 octane fuel.

Good fuel additive

Comments about 104® Octane Booster (10406):

I have a 1969 Camaro with a relatively higher compression ratio engine that I like to use this in. I don't have any detonation so I'd say it's helped the fuel.

Worked Great for Me

By GiGi

from Toledo, OH, United States

Comments about 104® Octane Booster (10406):

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.

It works

By Freddie

Comments about 104® Octane Booster (10406):

I like to experiment, so I put 2oz. of the 104 Octane in my lawn tractor 1 gallon tank. It ran better than it has in years - (15 yr old).

Octane Boost works!

By Dick

from Grand Blanc, MI, United States

Comments about 104® Octane Booster (10406):

Wow! My ZZ4 (355HP 350 SB) would ping even on 93 octane gas. There's no ping after adding Octane Boost. I would like to see a better dispensing method as my tank fill location is in the bed of a (street rod) pickup and it was difficult NOT to spill when adding it to the tank (maybe a flip-top squeeze cap like syrup bottles).

It's gettin there

By i95m3

from Orlando, FL, United States

Comments about 104® Octane Booster (10406):

Following the directions I poured the contents of the bottle into the almost empty tank of a 2004 Cayenne. The engine has been a bit rough idling and at speed for about a month and I was counting on the 104 to clean up the system a bit. Drove for about 150 miles and at the end of the trip the idle seemed to smooth out ever so slightly but I didn't really see any added benefits to performance or mileage. I would have to try another bottle to see if it continues to improve idle and or performance.

104+ Octane Boost

By FLMatt

from Vero Beach, FL

Comments about 104® Octane Booster (10406):

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.

Saves Money!

By RichW

from Dallas, TX, United States

Comments about 104® Octane Booster (10406):

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.

Give Your Engine a Boost

Comments about 104® Octane Booster (10406):

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.

Comments about 104® Octane Booster (10406):

Added the booster to a Tank of 86 octane because that is ALL they had on my last road trip in the Vette. Have always used 91 or 93 if I can find it, but I couldn't tell the difference. I will keep a bottle for emergency use from now on.

A bit more power.

By Tony K

from Marietta Ga.

Comments about 104® Octane Booster (10406):

I planned a trip to a popular mountain road in North Carolina this week end so it was a perfect time to try 104+. This is a locally famous road that is 11 miles long with 318 curves. You're either on the gas or the brakes. My car accelerated harder and smoother than usual. I can only attribute it to your product. Thanks!

No more knock!

By JeepsterXX

from St Clair Shores, MI, United States

Comments about 104® Octane Booster (10406):

Used just a little of this in my highly modified (built) Harley and this eliminated the pre-detonation (spark knock). Saves me a trip to the marina for the high octane stuff. It's supposed to also help clean fuel injectors but only time will tell on that opinion.
