LIQUI MOLY Viscoplus is an oil additive designed to stabilise the viscosity of engine oils and reduce oil consumption in modern engines. Viscoplus offers outstanding protection against mechanical and permanent shear losses to the oil under extreme running conditions and is effective against the thinning of motor oils due to frequent cold starts. This highly advanced product prevents oil moving past oil control rings while at operating temprature, a common problem on any mileage modern engine. Viscoplus won't change the factory performance of oil and avoids the use of incorrect oil grades to reduce oil consumption that can cause additional wear.
