India's petrol now carries ethanol at up to E20. Ethanol draws moisture out of the air, acts as a solvent on older fuel systems, and holds less energy per litre than petrol, so a fuel system specified for E10 or less is working harder than it was designed to.
These Liqui Moly formulations are made for ethanol-blended petrol. They bind moisture, protect the metal and rubber in the fuel system, and keep injectors clean. One dose per tank, German made.
Take the additive on its own, or a kit built around a motorcycle or a car. If you are unsure which suits your vehicle, get in touch and we will help you choose.
