Engine Additive Bottles

PET Capless Fuel System Rounds

Pretium’s new 12-ounce additive bottle features a special patent-pending neck design that allows it to be used in both capless and conventional automotive fuel tanks. Pretium’s capless fuel system bottle works by engaging the internal seal in a way that does not damage the seal and allows consumers to easily use the products. Samples are currently limited to three bottles per order.
