I notice that my car runs rougher with shell, but I always fill from the same one, which is cheapest, it looks like it gets business though.. when I fill with chevron the car runs smoother. This happened again after the shell nitro+ announcement.
Wondering if maybe its just this shell station? Going to keep filling with this station for another tank. Then change to another shell station. Is is possible the cheaper locations are usually the least traveled, and thus have the most stale gas?
Its funny too because when I had my car custom tuned it was on shell gas, but she just seems to like chevron.. unless its a station effect...
Anyone else have this happen?
