I'd do it if you don't mind your oil being thicker. Summer would probably be a better time than colder months.

10w30 M1 high mileage synthetic Thicker than a regular 30wt, great base stocks and add. pack I'm going to run it in my high mileage Ct200h that burns oil I spent hrs researching the majority of high mileage synthetic oils and imo this one seems to be the best according to data sheets

Curious as well! I was going to run M1 High Mileage Synthetic but this one is a good competitor too!
