Rislone Rear Main Seal Repair

Use When You Notice…

• Oil spots under your parked car: Classic rear main seal seepage — this treatment conditions seal material and reduces leakage progressively over a single oil interval.
• Oil level dropping between services: If you are topping up more often than usual, worn seals are likely the cause; this product restores their flexibility and sealing ability.
• Ticking or tappet noise on cold startup: Degraded oil film causes metal-on-metal contact; seal conditioners restore protective viscosity quickly during morning starts.
• High mileage or unknown service history: Second-hand vehicles benefit immediately from a sludge-clearing, seal-reviving treatment before long highway runs.
• Burning oil smell or blue exhaust smoke: Worn seals allow oil to reach hot engine surfaces or enter the combustion chamber — early treatment limits further damage.

Key Benefits

• Rear Main Seal Conditioning: Rejuvenates hardened rubber seals and O-rings so they swell back to their original sealing dimensions, reducing drips and seepage without dismantling the engine.
• Oil Film Reinforcement: Anti-wear chemistry strengthens the lubricant film between moving parts, critical for engines idling long hours in Delhi, Mumbai and Bengaluru traffic.
• Sludge and Varnish Removal: Detergent chemistry dissolves accumulated deposits in high-mileage Indian engines, restoring oil passages and improving circulation.
• Heat Stability: Viscosity improvers maintain protective oil thickness even when ambient temperatures push engine oil beyond its rated operating range in Indian summers.
• Universal Oil Compatibility: Works with all standard Indian engine oil grades — 5W-30, 10W-40, 15W-40 and 20W-50 — mineral or synthetic.

The Technology Inside

Rislone Rear Main Seal Repair combines seal-swell agents, high-temperature viscosity modifiers and ashless detergent dispersants in a single concentrated formula. The seal conditioners penetrate aged elastomer and nitrile rubber components, restoring their original flexibility and reducing the micro-gaps through which oil escapes. Viscosity improvers act as a molecular cushion, maintaining adequate oil film thickness during the prolonged idling and low-speed running that characterises Indian city driving. The detergent package dissolves varnish and carbon deposits from oil galleries, allowing the fresh additive chemistry to reach every surface that needs protection. This multi-action approach means one bottle addresses the root causes of oil consumption in ageing engines, not just the symptoms.

Dosage & Coverage

Add the full bottle directly into the engine via the oil filler cap — suitable for engines holding 3–6 litres of oil, which covers most Indian passenger cars and light commercial vehicles. Use at every oil change or as a mid-interval top-up treatment when symptoms appear. Always check the dipstick after adding to confirm total oil level remains within the safe operating range marked on the dipstick.

Compatibility

Safe to use with

• All petrol and diesel engines using mineral, semi-synthetic or full-synthetic engine oil.
• Standard Indian engine oil grades: 5W-30, 10W-40, 15W-40 and 20W-50.
• CNG and LPG converted engines — particularly beneficial as gas conversions accelerate valve stem seal and ring wear.
• High-mileage Maruti, Hyundai, Tata, Honda, Mahindra and Toyota engines.

Not suitable for

• Not a replacement for engine oil — always use alongside your regular engine oil, never instead of it.
• Cannot repair physically cracked, fractured or severely damaged seals — consult a mechanic for major leaks.
• Do not use in engines under active manufacturer warranty where oil additives are explicitly prohibited.

Why It Matters in India

India's ageing car fleet, vast used-vehicle market and common practice of extended oil-change intervals means millions of engines are running with hardened seals and accumulated sludge. Indian summers push ambient temperatures to 42–48°C — conditions that degrade engine oil and accelerate seal hardening far faster than in temperate climates. The combination of potholed roads, speed breakers every 500 metres and long stop-start city sessions puts relentless stress on engine gaskets and oil seals. Rislone offers an affordable, practical path to rejuvenating aging engines without costly workshop repairs or PUC-failing exhaust smoke.

How To Use

1. Warm the engine for two to three minutes, then switch it off and allow it to cool slightly.
2. Remove the oil filler cap and pour the full contents of the bottle directly into the engine.
3. Replace the cap, start the engine and check the dipstick to confirm oil level is within the safe range.
4. Drive normally — the treatment works progressively over the full oil-change interval.

Safety Note: Keep hands clear of moving parts when checking the dipstick with the engine running. Store unused product away from children and heat sources above 50°C.

Frequently Asked Questions

Will this work on my BS6 Maruti Swift or Hyundai i20?

Yes — Rislone Rear Main Seal Repair is compatible with BS6-compliant petrol and diesel engines. The formula does not interfere with catalytic converters, DPFs or OBD-II sensors, making it safe for modern Indian vehicles meeting current emission norms.

How long before I see results?

Many drivers notice reduced ticking noise and smoother cold starts within a few hundred kilometres. Full seal conditioning and a measurable reduction in oil seepage typically require one complete oil-change interval — usually 5,000–10,000 km depending on your service schedule.

Can I use this in my CNG auto-rickshaw or shared taxi?

Absolutely — CNG and LPG conversions often accelerate valve stem and ring seal wear due to dry combustion characteristics. Rislone engine oil treatments are well-suited to these high-utilisation applications and can extend time between costly overhauls.

Is Cash on Delivery available, and how fast will it arrive?

Yes, COD is available across India through naredi.in. Most orders are dispatched within 24 hours and delivered in 3–6 business days depending on your pin code — including Tier 2 and Tier 3 cities.

How often should I use this product?

Use once per oil-change interval for ongoing seal maintenance, or as a one-time treatment when oil leak or consumption symptoms first appear. For high-mileage vehicles or those used in severe Indian driving conditions, regular use at every oil change provides the best long-term protection.
