(I) 50% to 99% base oil by weight; (ii) 0.01% to 5% ionic liquid by weight; and (iii) 0.01% to 10% additive by weight; A lubricating composition comprising at least −54 ° C. pour point, a flash point of at least 246 ° C., and a dynamic range of 4.9 to 5.4 mm 2 / s at 100 ° C. Has viscosity. The lubricating composition according to the present invention is suitable for use in turbine engine oils and is useful for reducing sludge accumulation and reducing coking in the lubricating composition.
