Rislone4747 Octane Booster - 6 oz.

I used this on a 2021 Lexus, I recently purchased. The car had low miles when I got it, but I wasn't sure how long it sat on the lot not being driven. I was only getting approx 300 miles/tank and after putting a full bottle in the tank on two consecutive fillups, I am now getting 375-400 miles/tank(highway miles). I highly recommend this for anyone wanting to increase miles/gallon. I will start doing this once or twice a month moving forward. Unless you have other issues with your car, there is no reason EVERYONE shouldn't be using this!

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.

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.

It's a good product,good price
