Apples to Oranges
The best I've done is 1150km (690miles) on one tank (almost dry) from Calgary AB to Vancouver BC. Mind you this section is mostly down hill but I also did a lot of sight
seeing in between.
800 miles on one tank is probably possible but only with
certain fixed an favorable conditions like:
a) slightly taller tire
b) low rolling resistant tire
c) insane tire pressure
d) lower speed probably 5th gear all the way in the 1500-1800rpm range
e) coast in top gear during downhill
f) following a semi closely for extended period
g) pre-warm the coolant before each cold start
What a torture this kind of trip would be....
First off, let us compare the same vehicles with the same transmissions.
You have manual 6MT and I have a DSG. Big differnces when it comes to F E!
Had I had your 6MT for the same period with my GYs, I could have maybe made 800 miles,
maybe. I don't know how much better the higher geared late 6 Mts will do F E wise?
To go 800 miles with that set up. you would have to average 55 mpg!
I do have LRR tires and they are indeed taller. 205/
65-16s.
I do air them up, but how much difference that makes is debateable.
I did not do any drafting of other vehicles.
Around here, we not only have downhill areas, but we also have to climb
areas also to get back up here, as in roundtrips when returning home.
There is no pre-warming needed in this area, especially in the summertime.
My best tank of 731 miles was done over a nine day period, with mostly,
but not all, freeway driving. I did get into one stop-and-go traffic jam
that lasted for thirty minutes in which I covered only 1/2 mile.
Tank mileage was 50.222 MPG. I used 14.555 gallons.
That tank was for a nine day period, so there were indeed several cold starts.
It was really nice warm weather during this period, with most day temperatures
in the eighties and nineties, which our CR TDIs simply love.
Filled at the same pump at the same station with the vehicle in
the same position; As accurate as I know how to make it!
Your vehicle, being a later 6 MT should do better because of your much taller gearing!
