Rislone Rear Main Seal Repair

Use When You Notice…

• Oil spots under your parked car: A classic sign the rear main seal or timing cover gasket is weeping — this product reconditions the seal from inside.
• Oil level dropping between services: Slow leaks waste oil and money; the main oil seal conditioner arrests seepage before it becomes serious.
• Ticking or tappet noise in older engines: Degraded oil film on worn components causes noise — seal conditioning restores protective lubrication.
• Engine has high mileage or unknown service history: Ideal for second-hand vehicles where seals have dried out from age or irregular oil changes.
• Visible oil residue around the engine block: Seepage around the timing cover or valve cover gaskets responds well to chemical reconditioning.

Key Benefits

• Seal Reconditioning: Permanently restores shrunken rear main seals and O-rings common in high-mileage Maruti, Hyundai, Tata, and Honda engines.
• Heat Resistance: Formulated to remain stable at sustained 45°C+ ambient temperatures — essential for Indian summer driving conditions.
• Multi-Point Coverage: Treats rear engine seal, timing cover, and valve cover gaskets in a single 500ml treatment.
• Cost Saving: Eliminates frequent oil top-ups, reducing monthly running costs by hundreds of rupees without a workshop visit.
• No Dismantling Required: Simple pour-and-drive method — rejuvenates aging engines without costly workshop repairs or labour charges.

The Technology Inside

Rislone Rear Main Seal Repair uses a blend of seal conditioners, viscosity stabilisers, and proprietary swelling agents that penetrate hardened elastomer seals and restore their original pliability — a process sometimes called elastomer rejuvenation. Unlike petroleum-based fillers that swell seals temporarily and cause premature failure, this formula works through controlled chemical reconditioning, making the repair durable across full oil-change intervals. The anti-wear additive package simultaneously strengthens the oil film on journal bearings and camshaft lobes, reducing metal-to-metal contact during the cold-start phase — the most damaging period for any engine. This matters greatly in India's abrasive environment, where fine dust particles infiltrate past air filters and act as a grinding compound inside the crankcase. The result is an engine that runs cleaner, quieter, and longer.

Dosage & Coverage

Pour the full 500ml bottle into the engine oil filler cap after warming the engine for five minutes. One bottle treats engines with a sump capacity of 3–6 litres — covering most Indian passenger cars, SUVs, and light commercial vehicles. For severe or long-standing leaks, a second application after 800 km may be carried out; thereafter, treat once per oil-change interval as a preventive measure.

Compatibility

Safe to use with

• All petrol and diesel engines, including BS6-compliant vehicles
• Mineral, semi-synthetic, and full-synthetic engine oils
• Standard Indian oil grades: 5W-30, 10W-40, 15W-40, 20W-50
• CNG and LPG converted engines — where valve and ring wear is accelerated
• High-mileage engines in Maruti Suzuki, Hyundai, Tata, Honda, Toyota, and Mahindra vehicles

Not suitable for

• Not a replacement for engine oil — always use alongside your regular engine oil
• Cannot repair mechanically damaged or physically cracked seals requiring replacement
• Do not use in engines under active manufacturer warranty that explicitly forbids oil additives

Why It Matters in India

India's ageing car fleet, extreme seasonal temperatures, and the common practice of extended oil-change intervals leave millions of engines running with dried-out seals and accumulated sludge. The rear engine seal is especially vulnerable in vehicles navigating constant speed-breaker impacts and stop-go traffic in Delhi, Mumbai, and Bengaluru — vibration accelerates seal fatigue far faster than highway driving. Indian summers push ambient temperatures to 42–48°C, causing conventional engine oil to thin out and seep past already-compromised gaskets. Rislone Rear Main Seal Repair addresses these specific conditions, extending engine life without workshop downtime — a practical solution trusted by Indian mechanics in Tier 2 and Tier 3 cities nationwide.

How To Use

1. Warm your engine for 5 minutes, then switch off and allow 2 minutes for oil to settle.
2. Pour the complete 500ml bottle into the engine oil filler cap.
3. Check the dipstick to confirm total oil level remains within the safe operating range.
4. Drive normally for up to 800 km — the treatment works progressively as you drive.

Safety Note: Always handle engine oil and additives away from open flame. Dispose of empty bottles responsibly per local municipal guidelines.

Frequently Asked Questions

Is this safe for BS6 petrol and diesel engines?

Yes. The formula contains no compounds that interfere with DPF, catalytic converters, or BS6 emission control systems. It has been used safely in modern low-sulphur-oil-specification engines without adverse effects on PUC test results.

How long before I see results?

Most users notice reduced oil seepage within 300–500 km as the seal conditioners begin working. Full reconditioning of dried-out rear main seals typically completes over one entire oil-change interval of 5,000–7,500 km.

Can I use this in my CNG-converted Maruti or Hyundai?

Absolutely — CNG and LPG conversions run hotter and drier, accelerating wear on valve seals and piston rings. Rislone's seal conditioning agents are well-suited to these applications and help extend engine life in def-diesel and gas-converted vehicles alike.

Will it work on a high-mileage second-hand vehicle?

Yes — this is one of the most common use cases in India. Vehicles with 80,000 km or more often have hardened seals that respond very well to chemical reconditioning, making this an affordable first step before considering a full engine overhaul.

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

Yes, naredi.in offers Cash on Delivery and free shipping across India. Most metro and Tier 1 city orders are delivered within 3–5 business days; Tier 2 and Tier 3 locations typically within 5–7 business days.
