Fuel mileage

[jetfromtn]

This was my first long trip in my 40' DP Pathfinder. From Clinton Tn to Bonita Springs FL, pulling a HHR. I had not had a chance to check mileage before so did not know what to expect. My first stop at 305 miles, hand calculated 8.8 mpg. 2nd stop at 580 miles hand calculated 10.9 mpg. It is a 300 hp ISB, 2007 coach. Very pleasant surprise. I will be in Bonita till last of Mar. On last fillup I added Racor biocide. Anybody else use it?

At what crusing speeds did you get that economy? My brother has a 40' with the same engine and keeps it at 60 mph. He has a Jeep toad.

I was mostly around 60 to 65 in economy mode. Got in 1 accident backup for about 25 miles. The Allison 6 speed is a good piece of work.

I use biocide when I put her up for the winter.

Good job! That's some pretty good mpg!

We get between 11 for a high and 8.5 for a low. Depends mostly on wind, hills and my foot.

we just got back from ky averaged 8 to 11

You guys are killing me.

7.1 towing Ford Explorer. I've seen a low of 5.8 and a high of 8.5. All at 62/65 mph.

Me too, Rick. We usually get a range of about 6.8 to 7.5. The best has been 8.5, going downhill with a tail wind. I drive 58 to 62 towing and 65 to 68 not towing.

I think maybe you and I are keeping more diesel fuel receipts than anyone else. A good friend told me.........never trust a diesel engine owner's mpg estimate (unless it is similar to yours).

on a serious note rick my cruise is broke and i drive with a heavy foot no bs i was more than 10 on the average that was running 95 to 26 to 40 to 75 and back we went to walton ky the 8 came in when i had the gen running ! 275 hp cat baby but hey your coach is bigger !

We get as low as 7.5 and as high as 10.2 in our Beaver MH, 40', 330 Cat. I'd guess we average between 8 and 9 mpg. Depends on where you live. Mountains wreak havoc on mileage, low flat driving we figure we have a virtual econobox, Wind, speed, tire condition, engine efficiency and my big fat foot. I suspect not all diesel is created equal and have wondered about it affecting mpg's! If you are getting much better than 9 then you are doing something right. My old V10 Dodge managed 3-4 mpg so I figure I am on the good side of life.

In 30 days of traveling as you do now, considering fuel and food costs, how far can you go? I am discussing this on my Motorcycle Forum and I have been astounded by hotel and food prices they pay!

All my mpgs were hand calculated and the tank was filled completely into the neck. I filled up at Murphy oil and the pump nozzles are easier to use than at the truck pumps. The fuel used on the freightliner readout gave me better mileage than the hand calculations. It said I used 8 gallons less than actual.

On our cross country trip of about 9000 miles we averaged 8.0 mpg with a low of 6.8 and a high of 9.4. 360 HP, 8.3 Cummins 2007 complient, towing a 4300 lb Colorado PU.
