What Octane?

[Cobrajet]

I just came back from a trip from Northern Virginia to Nashville where I kept very good records of mileage because of this thread. I drove a total of 1321 miles (mileage corrected based on GPS), using 69.2 gallons, getting an average 19.1 MPG. I would say this was 95% highways miles, and probably 70% at 75mph. (I generally ran at 5-over posted speed.) First tank (ALL highway) I got 379 miles on 19.8 gals, with the low light on the last 4~5 miles. Tank two (a few local and stop-and-go miles) I got 381 miles on 20.1 gals, again with the low fuel light on for the last few miles. The next tank was all highway, and I played it safe filling after only 353 miles, 19.1 gals. The last fill was only a partial fill after 183.7 miles, 10.2 gals.

I generally do not get over 300 miles on a tank because I no longer make long commutes, but lots of short trips over the course of weeks between refills, which is the worst case scenario. It was nice to see that my VX is still capable of getting 19+ mpg on the highway. I have a few more trips planned for this year, so I won't need to rent a car to save money!

And to keep on topic - ALL regular unleaded! My VX has never seen premium, and never will!

Very nice and thought out! I love the detail provided -- and comparison between city/hwy! Glad to hear you can get 19mpg!

Nice job, Gregg!
