(54) Title: LUBRICANTS FOR USE IN BOOSTED ENGINES IN (57) : A lubricating oil composition and method of operating a boosted internal combustion engine. The lubricating oil com- 1-1 el position includes greater than 50 wt.% of a base oil of lubricating viscosity, calcium, nitrogen, molybdenum and boron. The weight ei ratio of Ca:N (ppm/ppm) in the lubricating oil composition is greater than 1.3 to less than 3.0, the weight ratio of Ca:Mo (ppm/ppm) ON in the lubricating oil composition is greater than 6.7 to less than 56.3, and the weight ratio of Ca:B (ppm/ppm) in the lubricating oil 1-1 --.... composition is greater than 5.0 to less than 9.8. The lubricating oil composition does not contain added magnesium from a magne- sium-containing detergent. The lubricating oil composition is resistant to deposit formation in the boosted internal combustion engine, 1-1 C as shown by its ability to ensure a TCO Temperature Increase of less than 9.0% as measured using the 2015 version of the General ei Motors dexos1® Turbocharger Coking Test.
