The absolute minimumquantity in the oil sump (before take-off) should be 2,5 litres (2,6 quarts), so besure to add sufficient oil to compensate the quantity of oil that remains in the oilcooler, -lines and -galleries. Attention: If AVGAS 100 LL is used frequently, we advise not to use full synthetic oil, as the oildoes not handle the lead deposits as well. More frequent oil changes are alsorecommended.
