From food to highly complex technology: DLG awards stand internationally for experience, competence and credibility. The DLG tests get to the heart of consumer-relevant quality criteria and guarantee neutrally tested quality.
The DLG Seal of Quality for oils, fuels, additives, windscreen cleaners and other operating fluids from the "vehicle accessories" sector creates trust, offers differentiation and ensures strong sales impulses at the point of sale.
