Wynns Engine Oil Stop Leak – 325ml (77441)

Description

Genuine Wynns · Part no. 77441

Wynns Engine Oil Stop Leak is a 325ml additive that revitalises the rubber and neoprene seals on the crankshaft, camshaft and valve stems to stop and prevent oil leaks without stripping the engine. It suits petrol and diesel engines with or without a turbo, and stationary engines, on mineral, synthetic, single or multigrade oil, including low SAPS.

Good to know

• Will it thicken my oil? No, Wynns says it doesn't change the oil's quality or viscosity, so the engine keeps running on the grade your handbook asks for.
• Can it help a car that drinks oil? If some of the loss is past hardened valve stem seals, softening them can reduce it; heavy use from worn rings or a turbo needs a mechanic.
• Does it suit a modern diesel? It is listed for low SAPS applications and won't harm catalytic converters, so it can go in a car with a particulate filter.

Which one?

For a sweating gasket on a family car, the NAPA Engine Oil Stop Leak 300ML (NAD1008) is a similar dose; for workshop use across several vehicles, the Lucas Oil Engine Oil Stop Leak 3.79 Litre (40279A).
