Fuel Additives & Treatments

Modern fuel systems are unforgiving of dirty injectors and poor-quality fuel, and a good additive is often the cheapest fix available before problems turn into a workshop bill. This range covers petrol and diesel treatments formulated to clean injectors, stabilise fuel in machinery that sits idle, and keep the whole fuel system running as it should. Wynns brings decades of specialist experience in injector cleaners and diesel system treatments, while Lucas Oil's additives are trusted for restoring lost performance and quieting noisy engines. Whether it's a once-off injector clean for a car that's lost its edge or routine treatment as part of a service schedule, the right additive protects fuel system components and keeps combustion clean.
