What kind of engine oil does Cadillac use?

For turbocharged engines, it is recommended to use 0w40 or 5w40 full synthetic engine oil. For naturally aspirated engines, it is recommended to use 0w30 or 5w30 full synthetic engine oil. Most models under the Cadillac brand are equipped with turbocharged engines, and for such engines, it is recommended to use full synthetic engine oil with a viscosity of 40. There are three types of engine oil: full synthetic oil, semi-synthetic oil, and mineral oil. Here is some extended information: 1. The base oil of full synthetic engine oil is artificially synthesized, so the molecular size and shape of this oil are regular. Full synthetic oil has good lubrication performance and a long service life. The base oil of mineral oil is refined from petroleum, and the molecular size and shape of this oil are irregular. 2. Mineral oil has a short service life and average lubrication performance. The lubrication performance and service life of semi-synthetic oil are between those of full synthetic oil and mineral oil.
I drive a Cadillac, and based on my own experience, the official recommendation is to use dexos-certified full synthetic oil, and this is not just a casual suggestion. Typically, the viscosity is 5W-30 or 0W-20, depending on the vehicle manual. For example, my XT5 uses Mobil 1 in 5W-30, which provides excellent protection. The benefits of using full synthetic oil are numerous: faster engine protection during cold starts, stable performance at high temperatures, and reduced wear to extend engine life. Never buy off-brand or non-dexos oils, as this could void your warranty or even lead to increased fuel consumption. I also make it a habit to change the oil every 7,500 miles for safety and reliability—don’t cut corners to save money. In practical driving, 0W-20 is more suitable in winter, while summer is less demanding. In short, following the manual is always the right choice.
