The lubricating oil ei composition is formulated to be resistant to turbocharger deposit formation in the boosted internal combustion engine, as shown by O its ability to ensure a TCO Temperature Increase of less than 9.0% as measured using the 2015 version of the General Motors dexos10 Turbocharger Coking Test. The lubricating oil composition may also have a low NOACK volatility, as measured by the p. method of ASTM D-5800 at 250° C.
