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 an expensive repair.
• Oil level dropping between services: Gradual oil loss strains high-mileage engines; this main seal stop leak solution arrests the loss without engine dismantling.
• Ticking or tappet noise on cold start: Often linked to low oil pressure from slow leaks — restoring seal integrity maintains pressure at the critical first-start moment.
• Oily residue around 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 on older Maruti, Hyundai, Tata, or Honda engines dry and shrink with age — this product revives them before weepage becomes a workshop bill.

Key Benefits

• Stops Rear Engine Seal Leaks: Chemically swells and reconditions dried seals — addresses the root cause rather than masking it with filler.
• Heat-Stable up to 48°C Ambient: Formulated to remain effective through Indian summer heat, protecting engines idling in peak Mumbai or Delhi traffic.
• Multi-Point Seal Coverage: One bottle treats the rear main seal, timing cover seal, and valve cover gaskets simultaneously.
• Oil-Grade Universal: Works safely with 5W-30, 10W-40, 15W-40, and 20W-50 — covering virtually every engine oil grade used across India.
• No Engine Dismantling Required: A pour-and-drive liquid solution that saves thousands in labour costs compared to a mechanical rear main seal replacement.

The Technology Inside

Rislone Rear Main Seal Repair uses a proprietary blend of seal-conditioning esters and elastomer rejuvenators that penetrate rubber and polymer seal materials at a molecular level. Unlike petroleum-based fillers that swell seals temporarily, these conditioners restore the original flexibility and lip-sealing pressure of aged lip seals and O-rings — delivering a durable result. The formula also contains viscosity stabilisers that counteract oil thinning during sustained high-temperature idling, a condition common in Indian stop-go city traffic. An antioxidant package further slows oil oxidation, which is accelerated by India's extreme summer temperatures and the dust that infiltrates engine bays on unpaved or poorly surfaced roads.

Dosage & Coverage

Add the entire bottle to the engine oil via the oil filler cap — one bottle treats engines up to 5 litres of oil capacity, covering most Indian passenger cars and light commercial vehicles. It can be added at an oil change or as a mid-interval supplement; after adding, verify the total oil level remains within the safe dipstick range. For best results, drive normally for 500–800 km to allow the conditioners to fully penetrate and recondition the seals.

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, 20W-50
• CNG and LPG bi-fuel conversions — common in Indian taxis and autorickshaws
• High-mileage Maruti, Hyundai, Tata, Honda, Toyota, and Mahindra engines
• BS4 and BS6 compliant engines

Not suitable for

• Not a replacement for engine oil — always use alongside your regular engine oil
• Cannot repair mechanically damaged or physically torn seals — suitable for dried, shrunken, or weeping seals only
• Do not use in engines where the manufacturer explicitly forbids oil additives under an active warranty
• Not suitable for gearbox, differential, or power steering systems

Why It Matters in India

India's ageing car fleet, the booming used-vehicle market, and the common practice of extended oil-change intervals mean millions of engines run with degraded oil and dried-out seals. The combination of 42–48°C summer ambient temperatures, abrasive road dust in cities like Kanpur and Ahmedabad, and constant stop-start traffic accelerates seal deterioration far faster than in temperate climates. For vehicles operating under PUC scrutiny, stopping oil weepage also helps prevent oil contamination of the exhaust and catalytic converter — protecting both engine health and emissions compliance. Rislone Rear Main Seal Repair offers an affordable, no-downtime solution suited to real Indian driving conditions.

How To Use

1. Warm the engine for 2–3 minutes, then switch off and allow it to cool slightly.
2. Pour the entire bottle into the engine via the oil filler cap.
3. Check the dipstick to confirm total oil level stays within the safe min–max range.
4. Drive normally — the treatment works progressively over the next 500–800 km.

Safety Note: Always work on a level surface. Do not overfill the engine beyond the maximum dipstick mark. Keep out of reach of children.

Frequently Asked Questions

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

Yes — CNG and LPG conversions often accelerate valve stem and ring seal wear due to the drier combustion environment. Rislone Rear Main Seal Repair is well-suited to these engines and is widely used in Indian taxi and three-wheeler fleets running on alternate fuels.

Is it safe for BS6 engines?

Yes — the formula is compatible with BS6 petrol and diesel engines and does not affect catalytic converters or DPF systems when used as directed. It does not alter oil viscosity beyond safe operating limits.

How long does it take to see results?

Many users notice reduced oil weepage and quieter engine behaviour within 300–500 km of driving. Full seal reconditioning and maximum leak reduction typically occur over one complete oil-change interval of 5,000–7,500 km.

Can I use this on my high-mileage Maruti Swift or Hyundai i20?

Absolutely — these are among the most common applications in India. Both models use engines with rubber lip seals that dry out and shrink after 80,000–100,000 km, making this product an ideal maintenance addition at the oil service.

Is Cash on Delivery available, and how fast is delivery?

Yes — Cash on Delivery is available across India, and naredi.in ships nationwide with free delivery. Most metros and Tier 1 cities receive orders within 2–4 business days; Tier 2 and Tier 3 locations typically receive within 4–7 business days.
