Friends vehicle, 2015 Chevy Equinox with the 2.4 DI engine, 31k miles. Since new, I've changed her oil with a Fram Ultra XG9018 and Dexos 5W30, mostly Smittys Super Syn 5W30, whenever the OLM hits 30%, which equals to around 5-5500k miles. It's short tripped alot. Shes a teacher, and the school is only 0.3 miles from her house, she takes her vehicle because she always has alot of papers and classroom supplies to bring,(otherwise she would ride a bike) so, 5 days a week, 0.3 miles to school and then the same in the afternoon. She does go on a long trip every now and then. I'm assuming this engine is susceptible to fuel dilution being DI. Would it be ok and possibly better to run AFE 0W30 due to her frequent short trips, or would fuel dilution be a greater concern?
