Oil: any API SD/SE or higher spec mineral only oil with a viscosity of 10W-30 (for temperatures between -25 and +30 degrees C) or 20W-50 (for temperatures above -10 degrees C). Synthetic oil has a nasty habit of leaving more deposits when it is burnt, which happens due to the oil injection into the cobustion chamber to lubricate the rotor apex seals. Fuel: it will run quite happily on 95RON or 85MON fuel provided the timing is set correctly.
