Rislone Axle & Differential – Seals Gear Oil Leaks, 500ml

Use When You Notice…

• Oil patch under the rear axle after parking: a classic sign of a worn differential seal — this differential leak sealer re-conditions the rubber before the leak worsens.
• Whining or howling from the rear at highway speed: starved gear oil causes metal-on-metal noise; restoring oil film stops the sound.
• Clunking on acceleration or gear engagement: low or degraded differential fluid loses its cushioning; this additive restores it.
• Gear oil level dropping between services: slow seep leaks drain fluid unnoticed — seal conditioning stops the seep early.
• High-mileage SUV or 4x4 with unknown service history: second-hand vehicles commonly have hardened seals; this product rejuvenates aging drivetrains without workshop visits.

Key Benefits

• Seal Restoration: Swells and softens hardened rubber seals to stop differential gear oil leaks, saving thousands in mechanic labour charges at Indian workshops.
• Noise Elimination: Reduces whining and gear chatter noticeable on Indian highways and city flyovers within a few hundred kilometres of treatment.
• Extreme-Heat Resistance: Formulated to remain stable at the sustained high temperatures generated in Indian summer driving conditions (42–48°C ambient).
• Extreme-Load Protection: Builds a high-film-strength lubricant barrier that guards differential gears on loaded commercial routes and mountain ghats.
• No Dismantling Required: No special tools, no workshop downtime — trusted by Indian mechanics as a practical first-line repair before a full differential overhaul.

The Technology Inside

Rislone Axle & Differential Gear Repair uses a concentrated blend of seal conditioners, extreme-pressure (EP) additives, and viscosity stabilisers. The seal conditioners penetrate aged rubber, restoring the elasticity that heat cycles and mileage have stripped away — directly addressing the root cause of most differential leaks. EP additives form a sacrificial boundary-lubrication layer on hypoid gear surfaces, reducing metal fatigue under the shock loads common on Indian roads. A viscosity stabiliser ensures the treated gear oil maintains its protective film even when differential temperatures spike on long ghat descents or during stop-go city commutes in Delhi or Mumbai.

Dosage & Coverage

One 500ml bottle treats up to 3.5 litres of gear oil — covering the differential of most Indian cars, SUVs, 4x4s, and light commercial vehicles in a single application. Pour the entire bottle into the differential housing via the filler plug; no partial dosing is required. For best results, treat at every gear-oil service interval or immediately upon noticing early leak or noise symptoms.

Compatibility

Safe to use with

• All conventional, semi-synthetic, and full-synthetic differential gear oils
• GL-4 and GL-5 rated gear oils in all common viscosity grades (75W-90, 80W-90, 85W-140)
• Cars, SUVs, 4x4s, pickup trucks, and light commercial vehicles
• High-mileage Maruti, Hyundai, Tata, Mahindra, Honda, and Toyota drivetrains
• Rear-wheel drive, four-wheel drive, and all-wheel drive differentials

Not suitable for

• Not a replacement for differential gear oil — always use alongside your existing gear oil
• Not intended for manual or automatic gearboxes — use a transmission-specific Rislone product for those systems
• Cannot repair mechanically damaged gear teeth, broken bearings, or severely worn pinion shafts
• Do not use if the manufacturer's active warranty explicitly prohibits oil additives

Why It Matters in India

India's roads subject differentials to punishment that temperate-climate formulations are never tested against — a speed breaker every 500 metres in Bengaluru, fully loaded Boleros climbing Himalayan passes, and ambient temperatures that push differential housing temps well above 100°C in May and June. Indian vehicles are also kept 10–15 years on average, meaning seals harden and shrink long before the vehicle is retired. A quality differential sealant like Rislone provides an affordable, practical solution that Indian mechanics in Tier 2 and Tier 3 cities routinely recommend before advising a full axle strip-down.

How To Use

1. Warm up the vehicle by driving for 5–10 minutes to thin the existing gear oil.
2. Locate and carefully remove the differential filler plug using the correct hex key.
3. Pour the entire 500ml bottle into the differential housing, then replace the plug securely.
4. Drive normally — the formula works progressively over the first 500–800 kilometres.

Safety Note: Allow the differential to cool before removing the filler plug to avoid contact with hot oil. Dispose of the empty bottle responsibly per local municipal guidelines.

Frequently Asked Questions

Is this safe for BS6-compliant vehicles like the Tata Nexon or Hyundai Creta?

Yes. Rislone Axle & Differential Gear Repair is added to the differential housing, which is a sealed mechanical system entirely separate from the BS6 emission control components (exhaust, DPF, catalytic converter). It will not affect your vehicle's PUC test results or emission compliance in any way.

How quickly will I notice results?

Whining and noise reduction are often noticed within the first 300–500 km of driving after treatment. Leak sealing and full seal conditioning typically complete over one full service interval — usually 5,000–10,000 km depending on your driving pattern.

Can I use this in the front differential of a 4x4 like a Mahindra Thar or Scorpio?

Yes — the formula works in both front and rear differentials. Apply one bottle per differential housing for complete coverage across a dual-differential 4x4 drivetrain.

Is Cash on Delivery available on naredi.in?

Yes. naredi offers Cash on Delivery across India, including Tier 2 and Tier 3 cities. Free delivery is also included on all orders, with no minimum order value required.

Can this be used in a CNG or LPG converted vehicle's differential?

Yes — CNG and LPG conversions do not affect the rear differential system. The formula is fully compatible with differentials in converted vehicles, which are common in Indian taxi and commercial fleets.
