WYNN'S 50664 Engine Stop Leak Additive - 325ml
Purpose and Specifications
Stop engine oil leaks fast without tearing down your motor. This premium 325ml additive from WYNN'S restores flexibility to hardened rubber and neoprene seals, O-rings, and valve stem seals in petrol, diesel, and LPG engines. It lubricates seals to keep them soft and working right, preventing drips from dried-out parts. Safe for all mineral and synthetic oils up to 6 liters - just pour in the whole bottle. Won't change oil thickness or hurt catalytic converters. Compatible with low-SAPS oils, but skip if you have wet timing belts.
- Prevents leaks at seals without engine disassembly
- Works in cars, trucks, and stationary equipment
- Treats up to 6 liters of oil per bottle
- Fully effective after driving 200-300 km
When to Use / Replace?
Use at the first sign of oil spots under your vehicle or low oil levels from seal wear. Ideal for high-mileage engines over 100,000 km where seals harden from heat cycles between -30°C winters and 120°C+ summers. Add during oil changes every 10,000 km or 12 months for prevention. One bottle lasts through your next service - reapply as needed if leaks return. Shelf life is 5 years unopened in cool, dry storage.
