Rislone Hy-per Fuel Octane Booster,6 fl. oz, 1 Pack,4747

The Ruslone Octane booster is the cats meow. Its more cost effective than auto parts store boosters, actually raises the octane 2 full points (ex. 87 to 89), and is well worth it. Go to their site and itll explaine more and with next level detail. And yes, I read it. I drive a HEMI powered vehicle. The manual recommends 89. 87 octane is $.40/gal or more cheaper. At the time of writing this octane booster is 2.56. I put 20 gal in at a time of 87 octane for an average price of $90. At 89, my wallet is hit for over $100. The additional cost of the booster still keeps me under $100 per tank... for now. What is the performance value? My truck runs a bit smoother and has a 1.5 mpg increase in economy per gallon. Getting 15.4 over 13.9 mog adds to the overall value of this product. I will continue using the octane booster. Thank you Rislone for making a product worth my time.

I use it in my Audi R8 on trips, I cant feel a hug e butt power increase but it does love it, idles better, ( yes ive done carbon cleaning) it burbles and all like a happy kid again where before it just growled... it run out great been using it for like 6 months no off and on when road tripping, engine has 13.1 compression - flat plane - hot rodded v8 revs to 9k, ported / polished intake, all titanium valve train etc, great little boost for it time to time, no probs with sensors or stuff. no dash lights, Id say give a few, not just one a try. then decide. for me its a win, so I keep 4/5 on hand all the time.

Gasoline is expensive and so are octane boosters! For the price point, this is a good value. This product treats 20 gallons with a octane increase of 2 points. I use this in a 5.7L Hemi with 282,000 miles on it. Give it some time. I sense it works well. Quick start ups,acceleration, smooth idle. Gas mileage increase, not so much.

I've used the Rislone Hy-per Fuel Octane Booster a few times now, and it has made a noticeable difference in my car's performance. It's easy to use and has helped improve fuel efficiency. Highly recommend for anyone looking to boost their fuel octane rating.

Great price
