Rislone Rear Main Seal Repair

Use When You Notice…

• Oil spots under your parked car: Classic rear main seal weepage — this product chemically restores the seal before the leak worsens into a costly repair.
• Engine oil level dropping between services: Gradual oil loss strains high-mileage engines; this main seal leak stop solution arrests the loss without dismantling the engine.
• Ticking or tappet noise on cold start: Often linked to low oil pressure from slow leaks — restoring seal integrity helps maintain pressure at the critical first-start moment.
• Oily residue around the timing cover or sump: Multi-seal coverage treats several leak points simultaneously in a single application.
• Recently purchased a used or high-mileage vehicle: Seals worn over years of Indian stop-go traffic and summer heat shrink and harden — this product reverses that process affordably.

Key Benefits

• Stops Rear Main Seal Leaks: Chemically reconditions the rear main seal to restore its original pliability and stop active oil seepage.
• Protects in Indian Summer Heat: Formula validated at 42–48°C ambient temperature, protecting engines in Indian summer heat without breaking down.
• Multi-Gasket Coverage: One bottle treats the rear main seal, timing cover, valve cover, and O-ring gaskets common in high-mileage Indian vehicles.
• No Workshop Downtime: Suitable for high-mileage Maruti, Hyundai, Tata, and Honda engines — simply pour in and drive.
• Extends Engine Life: Extends engine life in Indian driving conditions — heat, dust, and stop-go city traffic — by maintaining oil pressure and seal integrity.

The Technology Inside

Rislone Rear Main Seal Repair uses a proprietary blend of seal conditioners, elastomer rejuvenators, and viscosity stabilisers that work at the molecular level to reverse the hardening and shrinkage that causes rear main seal failure. The active seal-swelling agents penetrate dried rubber and polymer seals, restoring flexibility without over-expanding — preventing the secondary leaks that cheaper products cause. A complementary anti-wear additive package protects bearing surfaces during the critical period when oil pressure has been compromised by a slow leak. Unlike petroleum-based fillers that temporarily mask symptoms, this liquid formula chemically bonds with degraded elastomers — the same mechanism used in professional engine reconditioning. The result is durable seal restoration that holds through the sustained high-temperature cycling that Indian urban engines experience daily.

Dosage & Coverage

Add the full 500 ml bottle directly into the engine via the oil filler cap — one bottle treats engines with a 3–6 litre oil capacity, covering the majority of Indian passenger cars and light commercial vehicles. Use at every oil change or as a mid-interval top-up when leak symptoms first 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 passenger car and SUV engines
• Mineral, semi-synthetic, and full-synthetic engine oils
• All standard Indian engine oil grades: 5W-30, 10W-40, 15W-40, 20W-50
• CNG and LPG bi-fuel converted vehicles
• BS4 and BS6 compliant engines

Not suitable for

• Not a replacement for engine oil — always use alongside your regular engine oil
• Cannot repair physically cracked or structurally damaged seals or engine casings
• Do not use in engines under active manufacturer warranty if oil additives are explicitly prohibited
• Not intended for gearbox, differential, or power steering systems

Why It Matters in India

India's roads place extraordinary demands on engine seals. The combination of 42–48°C summer ambient temperatures, abrasive dust infiltration, and constant speed-breaker vibration accelerates seal ageing far faster than in temperate markets. Millions of Maruti Alto, Swift, Hyundai i10, Tata Indica, and Honda City engines are operating well beyond 1,00,000 km with original seals — making affordable seal reconditioning a practical necessity, not a luxury. With BS6 emission norms tightening PUC requirements, maintaining oil integrity also helps engines pass emission checks by preventing oil-burn that raises HC and CO readings.

How To Use

1. Warm the engine for 3–5 minutes, then switch off and allow it to cool slightly.
2. Remove the oil filler cap and pour the entire 500 ml bottle into the engine.
3. Replace the cap, check the dipstick, and top up with engine oil if needed.
4. Drive normally — the formula works progressively over the following 500–800 km.

Safety Note: Do not overfill beyond the MAX dipstick mark. If the oil level was already at MAX before adding, drain a corresponding amount before use.

Frequently Asked Questions

Is this safe for BS6 engines in my new Maruti or Hyundai?

Yes — the formula contains no compounds that damage catalytic converters, DPFs, or oxygen sensors required by BS6 emission standards. However, if your vehicle is within the manufacturer's active warranty period, check your owner's manual regarding oil additive use before proceeding.

Can I use this in a CNG or LPG converted engine?

Absolutely. CNG and LPG conversions run hotter and leaner than petrol operation, accelerating valve stem seal and rear main seal wear. Rislone's seal conditioners are well-suited to these applications and help maintain oil pressure in bi-fuel engines commonly used in Indian cities.

How long before I see results?

Most users notice a reduction in oil consumption and oil spots within 500–800 km of driving. Full seal reconditioning and leak elimination typically complete over one full oil-change interval of approximately 5,000–7,500 km.

Will this help my vehicle pass a PUC emission test?

Indirectly, yes. Rear main seal leaks can allow oil to reach the combustion chamber, increasing HC and smoke emissions. Stopping the leak with this product helps restore clean combustion and may improve PUC readings over time.
