ECOMAX Fuel Treatments

Advanced oils, lubricants and treatments since 1887

Fuel treatments for diesel and petrol engines

Millers Oils ECOMAX is our flagship range of fuel treatments, developed to help maintain engine performance, improve fuel efficiency and support long-term engine health.

Suitable for modern petrol and diesel vehicles, ECOMAX is designed to enhance fuel quality while cleaning and protecting the fuel system, supporting reliable performance for cars, vans, motorcycles, and commercial vehicles.

Why use ECOMAX?

Modern fuels are formulated to meet increasingly stringent emissions standards, but everyday driving can still lead to deposits forming within the fuel system. Over time, these deposits can reduce engine performance, affect combustion efficiency and impact fuel economy.

ECOMAX fuel treatments are formulated to enhance fuel quality while helping keep the fuel system clean. Designed for regular use at every fill-up, they form part of a proactive maintenance routine, helping to prevent problems before they develop rather than addressing them once they occur. Regular use of ECOMAX can help support:

Increased power
Improved fuel economy
Cleaner injectors and fuel system components
More efficient combustion
Reduced exhaust emissions
Protection against fuel system wear through added lubricity
