Next time try with out cruise control, even on my F10 five series it leaves a bit of throttle on going down hill....or even better get your wife to drive, my wife borrowed my 5 series with her buddies to do a road trip and got 870 kms, best I've ever got near to is 600km...go figure :-)

Got 1000km out of a 335d I had easy...

Cheers

I love that on a trip in my '05 3.0d the range counter is pinned at "999" for the first two hours!

Well... I should point out that's in kilometres... but it's IS kinda cool.

I have had around 1,300km from the 90 litre tank on a trip. Was a serious tail wind for part of it though, so it doesn't really count.

^I'd like to know about fuel economy improvements as well with the 6MT - its probably even more dramatic on my 5MT.

75mph in my 5MT is approx 3700rpm

So, your 5th has a 1:1 ratio, Multiply that by the 4.1:1 and you get a 4.1:1 Final drive ratio. Now, If you did a diff swap, you could get your ratio to 3.64:1. (Thats your 5th ratio of 1:1 multiplied by the new diff ratio of 3.64:1.) Your final ratio with the diff swap of 3.64:1 would be just slightly higher than 6th gear with the 4.1 diff, which is roughly 3.5 ish. Thats pretty sweet...

I'll take a video with 5th gear and 6th gear comparisons at different benchmark speeds as well as the full spectrum from 1st gear. 1st gear is absolutely better. I'm headed to SLC tonight for a concert (silver sun pickups) so I can show you how it pulls through a climb in the canyon, highway entrance at 80+ and a bonus. I'll also show you mileage snapshots during the trip to kinda give you an idea. My city mileage is about 19-20 consistently and highway is almost always 25+. I got 30-31 mpg on a trip over the summer coming back from the Tetons. This was US 89 scenic route with lots of fun twisties and mountains.

Your mileage will almost always plummet in the winter due to winter fuel blends.

No need to mention the mileage I get.

The most accurate way to check mileage is to fill the tank, write down the odometer mileage, drive to 1/4 tank or less. Fill it up, subtract the current mileage from the initial reading and divide that difference by the number of gallons needed to refill the tank. To get even closer accuracy, follow the same procedure for several tanks of fuel then add the mileage results together and divide that by the number of tanks burned.

That's how my android ap calculates it... use Fuelog at every fillup. I'm averaging about 18.39mpg from the 4.8is (since August) with a best of 20.76mpg coming back from Cali. Doing 65mph though this thing I'm sure could hit 22mpg. Here in TX though it's hard not to utilize the 80mph speed limits.
