Using the wrong additive is like giving someone the wrong medicine. This is why LIQUI MOLY adds an additional safeguard to ensure motorists always use the right additive. The new spouts for fuel additives prevent gasoline additives from going into diesel tanks and diesel additives from going into gasoline 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. The price to pay for this is that they are also very sensitive. Using a diesel additive in a gasoline engine or a gasoline additive in a diesel engine can have devastating consequences. For its new spouts, 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 spouts for LIQUI MOLY additives now have different diameters. The spout 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. “It’s an additional safeguard against mistakenly picking up the wrong additive,” says David Kaiser.
The new spouts work just as well on cars without a protection flap on the fuel tank, of course. LIQUI MOLY is switching its additive production to the new spouts, so for a while these products will be available with both the old and the new spouts.
As before, LIQUI MOLY additives also have a colour code 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.
