Thanks for the head's up
Ok, I just went to GASBUDDY.COM on this laptop and it showed me the prices in the town I'm parked in (Which is not the town I want the prices in but hey, I'm only 3 miles from the nearest gas but only 2 miles from the city limits)
To find Diesel, at the top of your screen it says REGULAR.. Click on REGULAR and a drop down menu appears. Diesel is the last item, It worked, I tested it.
To the left of "REGULAR" is the name of the town I'm connecting from (NOTE: if you are connecting cellular that may be many miles away) I typed in the name of the town, State where my mail box is (1,000 miles away) and sure enough the gas prices for that showed up (IE Battle Creek, MI, Tuson, AZ, Los Angles, CA) none of which are where my Mail box is)
So it's easy, Just the fact the type of fuel is a drop down is not well marked.
Have not checked out the updated cell phone app as the phone is busy with other stuff but suspect it's going to be the same.
Oh, I also tried just a state in the search box (the box with the town/state in_) Sure enough, I typed in OH and got the lowest prices in all of Ohio.
