Mileage On Cummins ISC 330

What kind of mileage is everyone getting on their ISC 330 Cummins? We were told that we would see 10 mpg but only getting 7. We have a 34 Monaco Windsor towing a Mazda Pickup.

How fast do you drive?

When you checked were you fighting headwinds a lot?

7 seems a little low. Most seem to get 8 or 9, but if you've got a heavy foot, 7 is probably about right.

DW normally is doing the driving with the cruise on at 55. Very seldom get to 65 mph so heavy foot wouldn't be the case. We have not used the economy button so maybe that is our problem

I think you would do better with cruise and economy mode. deSanford

I've seen as high as 9.3 cruising at 62 across the plains with a bit of a side wind, and as low as 6.5 dragging a jeep and trailer up and down the mountains in Colorado. I strongly suspect 10 is a bit optimistic at best at least for our rig.

Coach is ~25,000lbs wet with some stuff on board, add the Jeep/trailer and it's pushing 31,500.

7 mpg average is about right if you're towing a towed and try to maintain 65 or more. I don't really worry about the fuel mileage though.
On on uphill pull I will see about 3 mpg, downhill 256 mpg and steady cruise at 60 on the flats around 14 to 16 depending on the wind. These are the VMSpc instantaneous readouts not the average.

I love threads about mileage. I had a 275 Cummings in my first DP Journey. Pulling a 16 foot v nose trailer I could get 9.3 at 65 MPH without 10.2 and that changed according to terrain wind traffic etc.
My Monico Windsor same driving and filling to the same level of fuel which is a must I get anywhere depending on the same conditions 7.3 to 8.9. I installed a ScanGauge D recently hopefully it will help me get the best fuel mileage possible I will report if it helps. It does give a lot of good information for the cost.

I've seen avg mpg's as low as 7.5 and as high as 9.5. Thats not pulling a toad and not exceeding 65. Always use cruise and economy mode when conditions permit.

Happy trails..

On our last trip to the 'lower 48' we averaged 8.5 over 6500 miles. That is with no TOAD. We had some legs of the trip where we only got 7.0 and some that had over 12. When we pull the trailer loaded with four wheelers and gear, about 3200 lbs, we get between 7.0/8.0 depending on how hilly the route we take is.
I would suspect that the 7.0 that you are getting is about right. We are setting up a Durango to be our TOAD so I will have a better idea later this spring.

My 40' Windsor gets better at 65 than at 55mph, even in the "economy" mode on the transmission.

Like others, I have gotten as low as 7.1 (75mph) to as high as 9.2 (65 mph) almost always with the genny running.

I weigh in wet at 32,000 full of fuel.

jDL.....are you satisfied with the power of your ISC 330? Do you find yourself manually downshifting to create more power?

Testing on large fleets of Class 8 trucks by Cummins has shown a 30% difference in mpg between the best and worst drivers. So, before anyone can say what someone else should get we need to determine what kind of driver they are.

Stan, I am satisfied with it. I will turn it off of economy when I get into the hills. It climbs without much issue, even towing. I am sure it would be nice to have more power, but I really dont miss it.
