Auto Fuel STCs

Two STCs are always necessary, one for the engine and another for the airframe.
If your engine or airframe is not listed, please call us at 308-832-2200 for assistance. Prices are higher in Europe. This is necessary in order to compensate those in Europe who paid for European validation.

Please refer to Transport Canada document TP10737 for complete instructions regarding the use of auto fuel in Canada. Transport requires a specific cockpit placard that is not required by the FAA. We have these placards available and include them in all orders sent to Canada.


Prices in Europe are higher than in the US. This is because a great deal of expense was incurred in order to obtain acceptance of our STC's first by LBA and then EASA. FAA does not charge for these services, EASA does. For a quote on STC's in Europe please contact Vliegwerk Holland.

The European spec EN228 has been found to be substantially similar to ASTM D-4814. A great many Auto Fuel STCs have been sold throughout Europe where the disparity in fuel prices between avgas and auto gas is much greater than in the US. Auto gas is available at many airports in Europe. To order STCs for use in Continental Europe, please contact our rep, Vliegwerk Holland BV
