Reviews

104+® Max Octane Boost and Lead Substitute is rated 4.7 out of 5 by 62.

Rated 5 out of 5 by Carlton from Item to ALWAYS have on hand, Octane Boost 104+ Very Nice product which I always keep on hand for my vehicles, whether to add to my daily driver, or my Sundays cars. Maximum 104 Octane Boast works very well, it treat up to 25 gallons. I used about every other month. My Nissan runs so much better with fast pick up, and I really notice the difference when towing my Ranger Bass Boat. I add 104 Octane Boost very time I full my Porsche 928 up. The product is made by Sta-Bil which a very good company. You see them at Mecum Auctions all the time.

Rated 5 out of 5 by breezeinSTL from Made my '69 Merc Purr like a kitten I've been using additives & higher octane fuels in my '69 Mercury Marauder 429 for a long time to obviously help compensate for the lack of leaded fuel. The tank of fuel I used with this octane boost seemed par for course at first, certainly ran at least the same, but as I went through the tank the idle seemed a bit smoother and the valves seemed just a bit quieter. Might have been just me, but regardless, I'd rather add this than some of the other additives, both on price, contents of the additives and convenience of availability. Have to wait & see long-term. Overall happy for now!

Rated 5 out of 5 by Bugs from Great product Ford 347 stroker. Can't believe the way it runs over pump gas. Highly recommend this product.

Rated 5 out of 5 by Steel Wheels from My car needs this stuff! I've got an early '60s car with 11.25 to 1 compression ratio. It wants to run on after I turn off the engine even with the highest octane gas I can buy here in California. With this product, 104 + Octane Boost, the car runs great and no longer pings or runs on after shut off. Great product. It's the real deal.

Rated 5 out of 5 by DavidC77 from 104+ Max Really Works I really like this 104+ Max, I add it to each tank full... I really helps out with the power on my newer vehicles and really helps out my HotRod... I have a 1970 Buick and nowadays fuel doesn't cut it, it needs help and a bottle of the 104+ Max does the trick...

Rated 5 out of 5 by gt350 from Blown Away! First off, I was given a bottle for my opinion. I put this in my 69 Shelby GT350 today and honestly did not think I would notice any difference. It just something I would not buy. They just made a believer out of me. I have ran this car on the track with race fuel (110 Octane) and I know what that difference is between street gas. The race fuel did have more power than this but not much more. Race fuel is like $9 a gallon also. Make those ponies come alive and give it a try.

Rated 5 out of 5 by Eds cobra from Octane Booster I used the 104+ octane booster in my high performance Shelby Cobra. It works very well, since the highest octane pump gas I can buy is 92 and my engine responses much better at 95+. This product seems to make that happen.

Questions & Answers

I bought a bottle of 104 octane boost that treats 25 gallons, i'm trying to figure out how many ounces per gallon? I have 2 or 3 5 gallon containers and a 2 1/2 gallon container of mixed gas for small engines, Stihl power equipment.

Asked by: RPWJR

That would be a bit more than 1.5oz per gallon of fuel. Hope this helps!

When adding 1 bottle of 104 Octane Boost to 10 gallons of (typical) 93 octane street fuel (assume the base fuel includes up to 10% ethanol), what is the approximate new octane? Please give an actual value, with a +/- and specific caveats if necessary.

Asked by: sjsche

Ms. Taylor - Can you please explain what the make and model and state and size of the engine has to do with the octane level? The individual did not ask what octane was required by his vehicle – he asked what the new octane would be of the fuel. The fuel octane is what it is, regardless of what it is going into…

Exactly how much per gallon increase in the octane rating is there when used on 25 gallons of gas?

Asked by: Djecalifornia

About 1-2 is pretty non-specific – I would think testing your product with fresh gas would give a better answer. And I’m no chemist, but to say “the volume of the fuel does not affect the boost” seems absurd. So If I add one bottle to tanker truck full of 90 octane fuel, the entire 10,000 gallons would have a new octane level of 91-92? I don’t think so…
