About This Product
Why the Rislone Concentrated Rear Main?
The rear main seal is the seal between the engine block and the crankshaft — when it fails, engine oil drips from the back of the engine onto the gearbox bell housing and the ground. It is the most common oil leak in cars over 80,000km. Replacing the rear main seal mechanically is expensive — typically ₹8,000–20,000 because it requires removing the gearbox to access. The Concentrated Rear Main Seal Repair is a chemical fix — it conditions the seal to stop the leak without any disassembly.
How It Works
The 3-step process explained
1
Targeted Seal Conditioning
Concentrated formula specifically calibrated for the large rubber seal around the rear crankshaft.
2
Seal Rejuvenation
Penetrates the aged, hardened rubber and causes controlled swelling to restore the seal's original diameter and contact pressure.
3
Leak Stoppage
Restored seal creates a tight contact with the crankshaft surface, stopping the oil leak.
How To Use
Step-by-step instructions
Add to the engine oil through the oil filler cap.
Do not overfill — check the oil level first and reduce by 500ml before adding if at maximum.
Drive normally for 300–500km for full effect.
Works best on slow seeps — a heavy drip may require 2 treatments or a mechanical repair.

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.
