Si owners: What gas do you use? What gas maximizes MPGs?
Sorry again for another gas thread. Just wondering what people are using in terms of fuel.
I've been using Shell V-Power exclusively for the past five years. I find that in comparison to other fuels (include Sunoco 94), that Shell 91 goes the longest distance. In terms of performance gains, I never noticed 94 to pump out a lot more.
I don't recall the last time I pumped Esso or PC. Care to share?
