Dear Vintage - Opel friends,
I'm pleased to be able to offer you the following article:

Mathe Classic fuel supplement lead substitute & fuel stabilisor, all Opels

Lead substitute is no longer necessary for well-run engines, is the colloquial saying. Which is correct in itself, this medium makes lead-supplement as a by-product, however this fuel supplement is responsible for many more positive things! Here is an excerpt from the Mathe product data sheet:

Mathe Classic Fuel-supplement is specially designed for older petrol-engines, that according to the manufacturer's guidelines once required lead-containing petrol. It balances out the lubricating properties of the no longer lead-containing fuels of today and builds up a protective layer on the valve plates and seats. Additionally, it prevents deposits on the valves and spark plugs (also suitable for diesel systems).

Mathe Classic fuel-supplement offers excellent protection from corrosion, as the collection of condensed water is prevented and at the same time all moving parts are lubricated within the fuel system (pumps and valves).

Furthermore it conserves and protects the fuel from aging and oxidation, it works as a fuel stabilisor and keeps it ignition-stable. Particularly suitable for seasonal and long-term downtime from both Vintage and Modern Opels.

Product features:

  • Increases the knock resistance
  • Protection from valve wear and tear
  • Protection from fuel aging
  • Prevents deposition and corrosion
  • Prevents turning of the valves
  • Prevents engine damage
  • Cleans valves and combustion chamber
  • Ensures a clean combustion
  • Keeps the fuel ignition-stable


The mixture ratio is 1 : 1000. This is equal to 25ml Mathe & reg, Classic fuel-supplement per 25 litre fuel. It is recommended to add it everytime you refill the tank.


Add Mathe & reg, Classic fuel-supplement before refuelling. For complete functionality, it is recommended to add the supplement to every fresh tank of fuel!

ATTENTION: The fuel amount should at least match the reserve volume. Usable in all petrol and diesel fuels!
