AGA/Cooker Additive

Also for boilers

If you have an oil fired AGA or cooker, you may have heard in the press about problems of AGA's clogging up. This is due to The European Unions insistence on lower sulphur levels in domestic kerosene.

  • One bottle treats 1,000 litres
  • Lowers carbon build up
  • Inhibits sludge formation
  • Keeps fuel fresher for longer
  • Reduces service problems
  • Improves system efficiency

Bottles can be purchased in person at our depot or delivered by the oil tanker driver at your next delivery.
