Full details
Valvemaster 2 in 1 is an essential fuel treatment designed for classic car owners looking to protect their engines from the harsh effects of modern E5 and E10 petrol. By combining lead replacement technology with ethanol stabilization, this formula prevents valve seat recession and fights corrosion in older fuel systems, offering a cost-effective way to preserve engine longevity; however, it must be measured precisely before every fill-up to ensure proper concentration levels.

Setup, Compatibility & Care
To achieve the best results, store the bottle in a cool, dry place away from direct sunlight. The product is fully compatible with all classic engines that were originally designed to run on leaded fuel. Always keep a graduated measuring tool or use the integrated dosing chamber if available to maintain the 1:250 ratio. If you are preparing your vehicle for winter storage, add a full dose and run the engine for a few minutes to ensure the treated fuel circulates through the entire fuel delivery system, including the carburettors or fuel injection lines.
