Greetings everyone, I have a question regarding motor oil. I have a Mercedes-Benz C220 (W203) year 2001, Diesel, Automatic and it has 296,000 km (mileage) - I searched on Mobil1 official web site and used their search criteria based on my car's information and the site recommended 0W-40 Mobil 1 Advanced Full Synthetic Oil. is it OK to use it in my car? A friend of mine has the same car and he used it 0w-40 Mobil1 oil (with no issue) When I asked my mechanic, he said that because of the mileage it's better to use 10W-40 (or 5W-40 at least) Need your help/opinion on this matter and your recommendations are very appreciated. Thank you.
