after oil change you reset it in two places - under Service and then in engine ECU - oil-change.
you can change service interval to your desired distance. I think it was described on giuliaforums.com how to do it together with how to reset coupon number.
if oil degradation % didn't change after "oil-change" procedure in engine ECU it means it didn't finish successfully. repeat procedure. successful reset will show ~100% oil degradation.

Hi @shpuncik

When using MES, on US market Stelvios & Giulias, we can't change the oil change distance in the infotainment system - we're stuck with 9,600 miles. I tried to program it for 3,000 miles but MES just uses the 9,600 default setting

Again, when using MES, on US Cars, when we run out of the service coupons necessary to display oil change information in the infotainment system, we need to do a Proxy Alignment to get back the service coupons when we hit 0 (9 service coupons are the maximum we can program for - if I remember correctly).

As far as Oil Degradation - on US cars, MES appears to not be able to change that figure. I tried and couldn't get it to change, and spoke with others in the US that had the same issue. In my case, doing 2,000 to 3,000 mile oil changes, it's not a concern and mentally I've move on (but I can understand how it is a concern for others).

The guy that writes MES is in Bulgaria and probably does his software tests on EU spec cars. If anyone in the US wants to write about their MES experiences regarding these subjects please join the conversation
