I'm not sure what her str was filled with, as it was filled by someone else. She drives very easy, so seeing an almost 1/3 drop off in MPG really makes me wonder....

We have been holding them to their promise to repair certain problems and they aren't happy about it, especially since she was calling often for updates. I'll never buy a car again with promises of repairs, the cost of the repairs will come off the sticker price. All in all though, we did get the repairs done, but what a headache.

 

You need to remember a couple things fellas.....

Gasoline is a VERY regional thing, purposely blended for the expected climate in the region. Performance and MPG of the same car will be different in Texas than it is in Ontario. Differences in vapor pressures and some other technical values, not to mention varying additives.

Even though a pump may be labeled, 'Contains Ethanol not to Exceed 10%', in reality the content will vary greatly. More Ethanol means lower MPG, period.

The only true way to judge one tank from the next is to accurately measure the ethanol content of each fill. Not very practical or easy to do.

Cheers,

 

All very true.

 

In my case it's NJ & PA 90 miles away, basically the same climate. What ever the content is in NJ that tank from PA made a big difference that one time.
