...with 0W-20 and the dealer states they use a semi-synthetic blend for a $35.00 service. Instead I chose the 0W-20 full synthetic for a little more because I realized my prior '11 Si coupe would always burn through one quart using standard 5W-30 before the next scheduled oil change, so the full synth should eliminate any viscosity breakdown entirely...just a thought regarding my new experience with this model.
