forgot to add "pencil, paper, calculator"I have the 2019 CVT and have been very pleased with my mileage. My exagometer averages 3-4 over actual calculated. Got the car Dec 29 2018 and this is what I have done so far. My commute is an easy 20 min 16 mile 3 light ( i know awesome! used to be a 50 mile nightmare DC beltway) I'll be taking a trip to Canada in July. Really looking forward to see what kind of sustained all highway I will get. the 32 and 34 had significant highway cruising mixed in with regular driving.
27.6, 28, 27.3, 27.3, 27.7, 29, 30.6, 28.9, 29.6, 34.7, 28.4, 32.3, 31.1
I can see the reduction in pinging (although I don't know why you are hearing it in the first place) but, if premium fuel and regular fuel have fundamentally the same energy content, I don't know why your mileage went up and actual acceleration has increased. Maybe your engine computer is different and doing something creatively.I wanna give y'all a little secret here.. Premium fuel.. Yes its one of those "its a waste" sayings. But in our case (mine was the pinging engine) I put premium in and I noticed I gained 3-4mpg from it. I also have more power in the lower range.
The gains have been consistent over quite a few tanks and they are doing uber in the city.
