I just purchased a 2021 Mercedes GLC 300 4Matic SUV with the 2L turbocharged engine. It calls for oil changes every 10K or 1 year but I plan on changing at 5K.
In looking at the owner's manual it states that I should use either 229.51, 229.61 or 229.71. The 229.71 is listed with an asterisk stating it is the best for increasing fuel economy. The 229.51 appears to be 5w-30 or 5w-40, the 229.61 is 0w-30 and the 229.71 is 0w-20. I hope to keep this car for many years and many miles. What would be the best to use to mitigate future problems? I am thinking wear and general GDI issues to avoid.
Thanks for your thoughts
