...3-to-5 mph below the posted speed limit.
...follow their route (on the map) and maybe it'll disclose where all the Shell stations are that have/sell E0 fuel? Or, maybe they just simply used 91-93 octane which usually is E0?!?...They also are sponsored by Shell and used only Shell gas on this trip. Planned right, they probably only used E0 fuel as well, so that would help.
...just because the speed limit sign says 55MPH or 70MPH does not mean you *have* to drive 55MPH or 70MPH; you can drive slower than the speed limit sign. Although, it must also be stated that there are places where "minimum" speed limits apply.I read that and it really doesn't mean anything. Says nothing about the roads they chose, or the speeds on those roads. In Michigan the speed limit is a range on freeways between 55 - 70 posted, so what would that translate to?
