Does what it clams!
I got this for my older mustang I own. It's not daily driven and is just used as a pleasure car. With it being a 96 also I figured it was time to run some fuel system cleaner through it again. This has always been my go-to product. It does what it says it will do, and it does it very well! After running a tank of gas with this in it the car is running great again. Start ups are quicker and all the power of the 4 valve enging is back!

It Makes A Difference
Added 104 Octane Boost to my late model truck. The engine seemed more responsive and my fuel economy was slightly better than the previous tank of fuel without the additive. I plan to purchase 104 Octane Boost and add it to a another full tank of fuel and see if the results are similar.

Works good
I put this octain booster in my '71 Lincoln with a high compression 460. It always knocked on pump gas with lead substitute but this product stopped the knock and it seems to run smoother and faster (better throttle response) with no need for additional lead substitute.

Works well
I have a 59 T-Bird with the 352 cu. in. engine which does not run well on regular gas. I filled it with 90 octane, put the Octane Boost in the tank and drove it 120 miles this weekend. It ran like it should with no knocking and plenty of power.

104 Boost
I normally use 91 or 93 octane in my BMW and after trying 104 Octane Boost, the car felt like it pulled a little quicker but not really that significantly. It might be more noticeable on a car that doesn't usually use higher octane fuel.

104 Octant Boost
104 Octane Boost is a must use product for street rod engines with higher compression. 91-93 octane gasoline isn't enough to keep engines from pinging and not wanting to shut down when turning the engine off. Great product worked great

Made more of a difference than I expected
Tried a bottle of 104+ maximum octane boost on two different occasions in my truck. While there were no noticeable performance or gas mileage changes the idle was smoother than it has ever been.

Does the job!
I have a 70 Chevy Nova small block that has a rather lumpy cam. The car does not run well on 93 octane. Used the 104 and it really helped with performance. Good to go!

Works well
I tried the product about 2 weeks ago and it works well. The best part of this is that it works quickly to smooth a rough running engine. Thank you for a good product

Could not use
I read the directions on the bottle and on the very top in bold letters it read for OFF ROAD USE ONLY I did not feel safe using it in one of my cars or truck.

smoothed out my idle
I put in our 2006 Acura TSX and I know it smoothed out the idle. Performance seems to have back some edge which I'm enjoying. Worked for me as advertised.

Oct 104
I use about an oz of Octane 104 to 5 gallons cheap gas and what a serious difference on hills and freeway pick up.
Just bought 5 bottles for good supply.

Burnt my plugs
Put in my 2004ford f150 5.4 3v and it burnt up all of my plugs.
A costly repair considering the plugs cost over 100 dollars for 8 of them.
Terrible product.

It makes a difference
I was a little skeptical but I am convinced. I've used it for 2 tanks in my 04 SL 500 and it definitely runs quicker and smoother. I will continue to use.

Horsepower in a bottle
Poured 104 Octane Boost in with last fill up, immediately noticed a difference in the car's performance. Works as advertised, couldn't be more satisfied.

Great Product
Good way to clean your fuel system and boost the gasoline octane at the same time.Good for a tankful of gas. A little better performance in a bottle.

Great Product!
This product worked great in my motorcycle, the manufacturer recommended higher octane fuel for the motor and the 104+ was a great additive.

I received the Octane Boost and used it immediately in my Dodge Charger. Before the tank was half empty, I noticed a difference.
