About This Product
Why the Rislone Octane Booster -?
Engine knock — the pinging or rattling sound under acceleration — is caused by the fuel igniting too early in the combustion cycle due to insufficient octane. Indian petrol, even premium variants, can have inconsistent octane ratings due to supply chain variables and regional quality differences. The Octane Booster raises the effective octane of the fuel by 1–3 points — enough to eliminate knock and protect the engine from the long-term damage that uncontrolled detonation causes.
How It Works
The 3-step process explained
1
Octane Enhancement
Active compounds delay the ignition point of the fuel mixture, preventing premature detonation (knock).
2
Anti-Knock Effect
Higher effective octane means the fuel burns in a controlled flame front rather than spontaneously igniting under compression heat.
3
Engine Protection
Prevents the micro-damage to pistons and bearings caused by repeated detonation events.
How To Use
Step-by-step instructions
Add to a near-empty petrol tank before filling up.
Fill with regular or premium petrol.
For persistent knock: use every fill-up until the knock stops.
For performance driving or track days: use as a boost to available petrol.

How It Compares
vs other options
At ₹900, this is the lowest-cost Rislone additive. If your car is knocking on regular petrol, switching to premium petrol is a more comprehensive solution — but in areas where premium petrol is unavailable or unreliable, this octane booster is the practical alternative.
FAQ
Common questions
Are Rislone additives safe for Indian vehicles?
Yes. Rislone is an American brand formulating automotive additives since 1921. Their products are designed to be compatible with all modern engine oils, coolants, and transmission fluids. They are sold in over 70 countries and are safe for Indian petrol and diesel engines.
Can I use a stop leak additive as a permanent fix?
Stop leak additives condition rubber seals to swell slightly and re-seat. They work on slow seeps and minor leaks and the effect can last 30,000-50,000km. They are not a replacement for a mechanical repair on a major leak — but for minor seeps, they are a legitimate and commonly used solution.
Will fuel additives void my car's warranty?
No — adding a fuel system cleaner to the tank is no different from using a different petrol pump. Indian car manufacturers do not prohibit fuel additives. If a dealer ever claims this, ask for the specific clause in the warranty document.
How often should I use a fuel system cleaner?
Once every 10,000-15,000km or approximately once a year for normal use. If you use a specific station known for poor quality fuel, every 5,000km is reasonable. The cost is ₹900-2,400 and it takes 30 seconds to add to the tank.
