Oil and additive specialist LIQUI MOLY is introducing new pourers on its additive packaging to prevent products being used for the wrong application.

LIQUI MOLY says the additional safeguards will ensure motorists always use the right additive. The new pourers for fuel additives prevent petrol additives from going into diesel tanks and diesel additives from going into petrol tanks. “This provides additional protection from careless errors with expensive consequences,” says David Kaiser, Head of Research and Development with the German oil and additive specialist.

Modern engines are very efficient, but also very sensitive. Using a diesel additive in a petrol engine or a petrol additive in a diesel engine can have devastating consequences. For its new pourers, LIQUI MOLY uses a protective mechanism that many car manufacturers now install in their vehicles: a flap on the fuel tank opening that does not open until a pipe of the correct size is inserted.

For this reason, the pourers for LIQUI MOLY additives now have different diameters. The pourer for diesel additives is big enough to open a diesel tank protection flap, but too big for the opening of a petrol tank. In the same way, the flap of a diesel tank stays closed if you try to pour in a petrol additive.

As before, LIQUI MOLY additives also have colour coding to help tell them apart. Diesel additives have a red lid, petrol additives have a blue lid, oil additives have a black lid and radiator additives have a white lid.
