So you want me to run c30/ll-04 in this car with the situation at hand with North American fuels and a lot of dilution? lol. If anything this is a use case to why engines that led up to the S55 development should be running any decently priced 0/5w40 LL-01 certified oil off the shelf instead of later spec'd CAFE oil unless you're really worried about your emission equipment. The specs are very stout for LL-01/A40 and overkill for most, yet a tougher application like this at the correct interval is performing. Mind you..... at $25.98 a 5qt jug too vs the boutique options. I just purchased 3 OCIs of 5qt 5w40 Valvoline at $19.98, so this comparison will continue with Polaris Lab reports in the future with new M1 0w40 in the winters.I would start looking for a more robust oil, especially since you track the car. I run Ravenol VMP 5W30 in my '18 M240i. It's a true synthetic oil (group 4 base stock). Look for the VOA and UOA of this oil.
