AGA and Range Cooker Additives – Cleaner Fuel, Better Performance

26/02/2026

Oil-fired AGA and range cookers are designed to run continuously, so fuel quality really matters. Even small amounts of carbon build-up or fuel degradation can affect performance over time. Using a cooker fuel additive is a simple, low-cost way to protect your appliance and keep it running efficiently.

At Barton Petroleum, we supply kerosene for home heating and recommend specialist additives from FAST Exocet – a trusted brand specifically formulated for oil-fired range cookers. So if you own an oil-fired AGA, Rayburn or similar brand such as ESSE, Stanley or Heritage range cooker, we can help.

AGA Cooker Additives – FAQs

What is an AGA cooker additive?

A cooker additive is a fuel treatment added directly to kerosene. It improves combustion, helps reduce carbon deposits and keeps burners cleaner for longer.

Why should I use a cooker additive?

Over time, untreated fuel can lead to soot build-up, reduced efficiency and increased maintenance. A cooker additive helps:

  • Promote cleaner combustion
  • Improve fuel efficiency
  • Reduce carbon and soot deposits
  • Protect fuel systems and tanks

Is this safe for my AGA or range cooker?

Yes. FAST Exocet cooker additives are specifically designed for oil-fired range cookers, including AGAs and Rayburns, and are safe for cast-iron appliances when used as directed.

Will it reduce servicing and breakdowns?

Cleaner fuel means cleaner burners. Regular use can help extend service intervals, reduce call-outs and support reliable, consistent heat output.

Does it help fuel stored in tanks?

Yes. Additives help stabilise stored kerosene, reducing sludge formation, fuel degradation and corrosion, this is especially important where fuel is stored for longer periods.

How often should I use a cooker additive?

For best results, use with every fuel delivery or as part of routine fuel maintenance, particularly before winter when cookers work hardest.
