It would be good to be able to download ones own data or data for a vehicle class or model as a CSV file.

 

It would be great to be able to sort the database by any variable, and compare vehicles by selecting a subset of the whole.

 

4wd vrs fwd breakout for Suvs

 

Agreed - do not purge old data - the value lies in the depth of data. I don't see any changes required for the Next-Generation Mileage Database; Jason enjoy the summer before college.

 

I "third/forth" that idea. I was getting annoyed last week when the dashboard MPG was showing a significant drop from the previous tanks real-world number (hence the thread I started). When it came time to fill up, the tank had actually done slightly better than the previous one!

Of course, that manual calculation method assumes you fill the tank to exactly the same level each time, which may not be true. However over time the averages will be accurate.

BTW: On a similar topic, I recently put in gas w/o filling the tank, so I just included those gallons in the calculation, and kept the milage total going until I could completly fill the tank. All OK but now the stats show I have a 22 gallon tank and average of 16.8 galls/tank (even though the tank is theoretically 17 gals, I never run it that dry ! )

 

>>> It would be good to be able to download ones own data or data for a vehicle class or model as a CSV file.

I'll vote for that.

 

>>> Be sure to include the gasoline 'grade' is possible. I've noticed higher MPG when using 89-octane over 87.

I recently suggested someting similar to Jason, but will also post it here for public view:

When entering tank data I'd like to include fuel price paid, the particular gas station, (beginings of a gasprice survey?), the grade and brand of fuel (including (seasonal) additives) etc to see if there is any corrolation between those variables and the MPG

 

>>> Als as I've mentioned before, more choices for percent of traffic and highway.
Agreed

I've often wondered why the highway/city dropdowns are separate rather than a single/combined dropdown - is it possible to have 66% highway *and* 66% city ??

 

Merlin, they aren't separate. There's one for traffic and one for highway %. Also, please refrain from posting multiple times in a row.
