Rislone One Seal

Use When You Notice…

• Oil spots under the car after overnight parking — the seal conditioner targets crankshaft and camshaft seals hardened by sustained Indian summer temperatures.
• Whining or groaning from the steering pump — lip seal conditioners restore proper contact and typically reduce pump noise within 100 km of normal driving.
• Power steering fluid dropping between services — this oil sealant for car systems targets the exact lip seals that weep under heat and pothole shock loading.
• Gearbox oil seeping around the output shaft — acts as a gearbox sealer for both manual and automatic transmissions without requiring an oil drain.
• Heavy or inconsistent steering feel in city traffic — restores seal flexibility so the power steering system builds proper hydraulic pressure again.

Key Benefits

• Seals Multiple Systems: One bottle addresses engine, gearbox, and power steering leaks — reducing workshop visits and labour costs.
• Reconditions Aged Rubber Seals: Restores flexibility to hardened O-rings and lip seals worn by sustained 42–48°C ambient temperatures common during Indian summers.
• No Disassembly Required: Rejuvenates ageing engines without costly workshop repairs — add through the existing filler and drive normally.
• Extends Gearbox Life: Works as a gearbox gasket sealant to control seepage in high-mileage manual and automatic gearboxes common in 10–15 year old Indian vehicles.
• Reduces Steering Noise: Effective on aftermarket power steering systems and original-fitment units suffering from fluid loss and seal wear.

The Technology Inside

Rislone One Seal uses a blend of seal-conditioning esters and viscosity-stable polymers that penetrate aged elastomers, causing them to swell safely back towards original tolerances — restoring the sealing contact that prevents fluid loss. Unlike crude petroleum-based stop-leak products, the formula is calibrated to work without over-swelling seals or clogging narrow hydraulic passages in power steering racks and automatic valve bodies. The chemistry is compatible with mineral and synthetic base oils, meaning it remains effective across the wide range of oil grades used in India — from 20W-50 in older engines to 5W-30 in modern BS6 vehicles. A secondary anti-wear additive package also protects metal surfaces exposed by the original seal failure, slowing further deterioration while the conditioning treatment takes effect.

Dosage & Coverage

One 325 ml bottle treats a single system — engine, gearbox, or power steering — depending on where your leak originates; consult the label for per-system dosing guidance. For engine use, add to the existing oil through the filler cap and verify with the dipstick that the total level stays within the safe operating range. Use at every oil-change interval or as a mid-interval treatment when a leak is first noticed; do not exceed the recommended dose.

Compatibility

Safe to use with

• All petrol, diesel, and turbocharged engines using mineral, semi-synthetic, or full-synthetic oil.
• Manual and automatic gearboxes — acts as a gearbox sealant without requiring a fluid drain.
• Hydraulic power steering systems, including aftermarket power steering conversions.
• All common Indian engine oil grades: 5W-30, 10W-40, 15W-40, and 20W-50.
• CNG and LPG bi-fuel conversions, where seal and O-ring wear is accelerated.

Not suitable for

• Not a replacement for engine oil — always use alongside your regular engine oil.
• Cannot repair mechanically damaged, cracked, or missing seals — a physical seal replacement will be necessary in those cases.
• Do not use in vehicles where the manufacturer explicitly forbids oil additives under an active warranty.
• Not intended for electric power steering (EPS) systems, which contain no hydraulic fluid.

Why It Matters in India

India's roads are uniquely demanding — speed breakers every few hundred metres, sustained stop-start traffic in Delhi, Mumbai, and Bengaluru, and ambient temperatures that regularly exceed 45°C between May and June. These conditions accelerate seal hardening and fluid loss far faster than in temperate climates. With millions of Maruti, Hyundai, Tata, and Honda vehicles running beyond 100,000 km, sealing worn oil gaskets and O-rings common in high-mileage Indian vehicles is a practical priority for cost-conscious owners. Rislone One Seal offers an affordable, no-downtime solution that Indian mechanics and workshops trust before recommending expensive teardowns.

How To Use

1. Warm the engine or system briefly to normal operating temperature before adding the product.
2. Pour the correct dose into the relevant filler — engine oil cap, gearbox filler plug, or power steering reservoir.
3. Check the fluid level with the appropriate dipstick or reservoir markings and top up if needed.
4. Drive normally; the treatment conditions seals progressively over the following 100–500 km.

Safety note: Never exceed the maximum fluid level marked on the dipstick or reservoir. If a major leak is present, have the vehicle inspected by a qualified mechanic before driving long distances.

Frequently Asked Questions

Is Rislone One Seal safe for BS6-compliant engines in Maruti and Hyundai cars?

Yes — the formula is free from chlorinated solvents and is compatible with the tighter emission tolerances of BS6 engines. It will not affect your vehicle's catalytic converter, DPF, or oxygen sensors.

How quickly will I see results?

Power steering noise reduction is often noticed within 100 km of normal driving. Engine and gearbox leak reduction typically improves progressively over one full service interval of 5,000–7,500 km.

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

Yes — CNG and LPG conversions run hotter and often accelerate valve stem seal and O-ring wear. Rislone One Seal is well-suited to these applications and compatible with the oils used in bi-fuel vehicles.

Will it fix a heavy gearbox leak completely?

Rislone One Seal is highly effective on slow seeps and weeping seals — the most common type of gearbox leak in high-mileage Indian vehicles. Severely damaged or cracked seals will require physical replacement; this product works best as a gearbox leak sealant for worn but intact rubber seals.

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

Yes — naredi.in offers Cash on Delivery across India with free shipping. Most orders are delivered within 3–7 business days depending on your location; Tier 2 and Tier 3 cities are fully covered.

Complete Your Kit

Pair Rislone One Seal with these complementary treatments for a complete engine and drivetrain refresh.

• Rislone Engine Treatment Conditioner and Cleaner (44102) — dissolves sludge and varnish deposits in high-mileage engines before or alongside seal conditioning, maximising the benefit of both treatments.
• Rislone One Seal Stop Leak (44334) — a targeted stop-leak formula for more persistent engine oil seepage, ideal as a follow-up treatment if a specific leak needs additional attention after the first application.
