Today, I filled up using Petro Canada 87 octane. I figured I might as well try some different fuel grades as well to see what numbers I get. Results tbd
The Shell results are very conflicting. From a fuel economy perspective, Shell had the worst fuel economy numbers of any gas I have used thus far. But conversely, I also had one of the best driving experiences, with smooth idle and lots of get-up-and-go. If not for the fuel econ numbers, this would have been near the top!
