Dutchstar DP Mileage.. Just for fun

While waiting once again for a software update to download I was reading the Newmar forum and stumbled across a gas mileage thread where tons of folks were commenting on their mileage.. Well that go me curious so I averaged the 14 responses with mileage estimates and it worked out to 8.37. This was across all lengths/chassis/engine/toad postings...

Makes perfect sense to me. Seems absolutely correct. Certainly, it was our experience. About 9 without toad at 65 mph, about 8.75 with toad at same speed.

Interesting, here is where we sit so far:

Engine computer shows: Total miles- 5152.5, total gallons through engine-669.5 fuel mileage - 8.0

My math shows mileage at 7.696.

On 12/8/12 I read the Oasis and genny hours:

Oasis- 94.0

Genny- 8.8

Our last fill up was on 12/9/12 with total mileage sense we to possession on 9/8/12 of 3997.5 (how many we put on) with total gallons of diesel fuel purchased 675.593 (how many we bought). I did not write down the Oasis or genny hours at this fill up, it was very cold and windy. They both ran all night on the 8th.


I'm only keeping track for the fun of it and to further these discussions.

No "gas" mileage on a diesel!

Didn't buy a motorhome for it's fuel mileage, we got the Civic for that.

Never really verified it. I use 7.0 MPG for my fuel budget estimates.

You got me... I agree the only gas in my coach is from human sources...

When I asked what the fuel mileage was on my MH, I replied; "The short answer is I don't care".

I always went on to say it gets about 7 MPG.

I track my mileage to improve my driving habits. I don't push it too hard and the toad is not that heavy, but I have been unable to get 8mpg. Usually around 7.5. I am quite happy with what I get and don't spend a lot of time worrying about it. Our fuel bills increase when we are home, as we seem to drive the cars more then. Good reason to hit the road with the DP!

When I'm asked about my fuel mileage per gallon I enjoy answering it's around $40. per hour or about three times what my Jeep burns... I alsolike to add that my coach burns a gallon of fuel every 6-7 minutes (or 6-7 miles) on the highway. Nothing to be really proud of, but such it is.

$ 40.00 an hour to run your coach is a good answer. I may use that one myself. That seems to be what I'm paying.

I looked at my last 24 months of records. Drove 17,700 miles, purchased 2,450 gallons of diesel (29 fill ups), average price was $3.64 per gallon, and my mpg average was 7.23. I keep track detailed records mostly out of curiosity, doesn't affect my travel plans. I could do better on the mpg, but have a heavy foot.

That seems to be a hot topic for some people. I hate stats. Since I have the Coach, I calculated the mi per gal once (in Canada) and it was around 9-10 (our gallon is bigger and even more, we are in Liters !!)

1 Imp Gal = 1.2 US Gal
150 US Gal (my tank) = 124.9 Imp Gal = 567.81 liters

Mine (Cummins ISC 350) runs between 6 and 7 MPG. I usually remind the questioner that is for moving a 42000 pound house down the road at freeway speed.

Doesn't seem so bad after all, does it?
