Some car profiles feature a box called, "Potential Savings Per Fuel-up" and some feature, "EPA Estimates" (Here's how this mileage compares with the EPA estimates for this model). I'd rather show how my car compares to EPA estimates. Can I change my profile to show this info?
It's not an either/or situation, we try to show both options for all vehicles if we have the data available. The data we get from the EPA lists models in a different way and the system doesn't always match up model names precisely. I took a look at '98 Diesel Jettas and that was the case.
If you go back to your vehicle profile page now, you should be prompted to select your specific model from the '98 Jetta EPA models we have. Once you do that the EPA estimates should show up on your page.
The EPA provides a data download package of all their data, but they update that separately from their live website. It's a bummer, but it's a bit too much work to scrape their live site for the latest data. They really need to update the downloadable data but it seems to lag behind their site data by many months.
