From Chicago to the Finger Lakes region of New York at 76MPH I averaged 23.8 mpg. Seems to be right were it stays on my long day trips as well. 2003 XKR

 

White XKR

That is indeed gentle. Literally from the pump and back on to the freeway. I think the big key here is the octane as well as very gentle driving. The difference between 91 and 93 Octane is 2 mpg for me.

 

my 99 xk8 gets better fuel mileage than my everyday driver [96 xj6] .that being said,if your looking for best gas mileage then go for the econo-box,but i myself would prefer to go in style and just enjoy the ride...steve.

 

If it's an issue, drive the rental. The Jag costs money.

This afternoon, as I gently drove a back road, I told Abby, "I could probably improve my gas mileage if I can drove like this all the time. "
"if you drive like this, you might as well drive your truck. "

No wonder I love her.

 

Well I decided I'll just take my XK8, I don't visit my parents often and of course my other relatives in that town would love to see my car! I insisted my car is parked in the garage, my mothers corolla can sit outside for a few day!

It will cost less to take the XK8, I was just thinking of avoiding wear/tear etc. The cheapest rentals at brand name rental companies are ~120 and the mpg difference isn't enough to make it cheaper. I'm going with $4.25 gal. price. I always get premium grade.

 

It's a choice you are sure to be happy with.

Enjoy the trip!

 

Yep,

Good decision! Enjoy your drive! These cars were made for driving and life is for living.

We have better MPG in Oz than you guys because we have bigger gallons.

Seriously a Jaguar is made for these trips and will also benefit from a nice long drive.

 

Good choice!

It might be a few $$ pain but you and your family will remember the day you arrived in your Jaguar for a long time.

Don't forget to factor in the additional mileage for giving them all rides!

Have a great trip.

From London to Geneva 600 miles, 90MPH average, 24MPG, top up.

At no time was 160MPH exceeded.
That was what Brock Yates said about the first Cannonball Run.

A buddy of mine now decades ago explained it was always better to rent a car than take your own on long trips. I thought he was nuts until years later I took my own Mercedes on a long 4,000 mile trip and then checked the depreciation that is the hidden killer.

But if you are keeping your car forever it doesn't matter.

I will add that the biggest benefit of a rental is that when it breaks they bring you another one.

Happened to some buddies just last year on a trip from Paris to Rome and back....they put gas in a diesel......jet lag, they had gone straight from a flight from Australia to the rental agency and started driving the six hours to Geneva...doubt they would have done that with their Ferrari..... it not surprisingly died on them just ten miles from our house....they had wanted to take my car. Thank you no I had said, I prefer to pay my share of the rental.

It would have taken days to sort that out in my car not to mention the cost. They got another car and we were on our way the next morning, only slowed them down by about two hours. They did a bill for 900 euros later.

That said what is the point of living like a movie star if you are going to spend it in the garage.

Enjoy your trip and wowing the friends and family....isn't that half the reason you bought it?

cheers,

Country lanes with an XKR 20 US 24 Imperial
Long runs mainly autoroute 22 US 26 Imp.

 

got 23.74mpg from LA to S. Utah, not bad! That's with the AC on from roughly Las Vegas to the final destination. Saw a Fisker Karma on the way as well, it like many of the latest luxury cars owes a lot to the XK. The Panamera does too.
