Closely related ot: Mobil DTE Light is indeed widely used oil in Europe and even approwed by some model turbine manufacturers. I've been using it with Simjet, Jetcat and Booster turbines with no problems. The cost here - 20 litres plastic canister with taxes about 70 Euros and it's widely available. Toxicity is lower than MIL -specd turbine oils. Just google for DTE Light to find out more...
