Important: minimum octane and other requirements

For Robinson products, the minimum octane is 91 (RON + MON/2).
For Schweizer, the minimum octane is 93.

All fuels must meet ASTM Specification D-439 for leaded fuel or D-4814 for unleaded. Fuel containing alcohol is not approved, nor is E-85 fuel at this time.

Call (508) 842-4261 or e-mail us for more info.



EN228 was found to be substantially similar to D-4814. A great many STCs have been sold in every country in Europe and now increasingly in Eastern Europe. To order STCs in Europe, contact our rep, Vliegwerk Holland BV [].


*Prices and shipping costs differ in Europe due to EASA certification requirements.

As 100LL becomes increasingly difficult to obtain, we have been selling more and more STCs in Asia. Fuel in Indonesia, Malaysia, Thailand, Sri Lanka, the Philippines and elsewhere is satisfactory for use with our STCs.
