Here is an oil analysis for another SkyActive-G engine. No fuel dilution here like those mentioned in other UOA's. The vehicle is driven in Southern California, a good mix 40/60 city/hwy with lots of stop and go traffic factored in. I always let the engine finish its cold high idle start, which lasts for about 22 seconds. I use a lot of Arco 87 or Costco 87.
TBN still good at 4.6, I think the factory fill can make it past 7.5K miles with no problems.
