The Rislone Regimen: What's your goal?

I know my goals

Rislone USA

What Our Customers Are Saying:

  • I recommend a full bottle of Rislone in your crankcase if you’re looking to perhaps improve the performance of an old car like mine, or your new car. Use Rislone for general maintenance every oil change or so, quiet your loud engine idle, slowly remove sludge and to make you and your car happy. I am satisfied with Rislone and I hope that if you try Rislone that you’ll have excellent results.

  • Believe me when I say I think a lot of fuel additives don’t do much. This stuff is different, and I felt the difference right away, and I noticed my 2013 V6 Camaro has better performance in the summer heat than usual. This is a product that actually works in a sea of products that don’t. Thanks!

  • It is the best diesel treatment we have found, and trust me we have tried many. We currently use it for our entire diesel fleet.

    — S. Williams, Austin, T
  • Love this stuff… Been using it since I noticed what looked like scratches on my cam lobes. Ever since I started using it my lifters are way quieter and the wear on my cam loves seems to have stayed at the same level since I began adding this to my oil. Highly recommend it!

  • Rislone Complete Diesel Treatment is the flat-out best performance diesel engine fuel product I’ve ever used. Everyone who drives a diesel should know about it. Most don’t do anything, Rislone is the opposite. I’m happy my diesel shop recommended it to me.

Why Rislone?

There’s a lot riding on your vehicle. As one of the most expensive purchases you will make, your car, truck, van or SUV needs to be taken care of to guarantee durability, performance, value and safety. One important and often overlooked way to improve your engine, fuel system, and oil is to use Rislone performance chemicals.

Engine + Oil Treatment — To keep your engine clean and your engine oil lubricating at peak levels
Transmission Treatment — To help avoid leaks and slippage that can case serious damage

Our products allow you to maximize performance, or even recover power that has been lost over the years due to usage and wear.

Easy to use, our engine treatment, fuel treatment and diesel fuel additives give immediate improvements in performance that result in real gains:

Higher performance — You’ll get every last ounce of power out of your engine like the day it was made.

Greater durability — Your engine doesn’t have to work as hard when friction and internal drag are controlled.
