Shell Gas in the D
I have experienced this before with many vehicles that I have owned or use at work, but Shell gas just makes the D run better. I was putting 87 Octane in and switched to 89 on the last 2 fill-ups and did not notice a difference in performance.
So I filled up with 87 Shell for the first time a few days ago and the D just runs better, feels stronger, better part throttle and pick up. Just thought I would pass the info along. Maybe I will try Shell 89 but that will cost about 100$ in NYC.
