Miles vs Hours

[CKruse]

Please excuse me for starting this at night. I would like to see everyone post their miles and hours on their 03. If nothing else, I bet several don't realize they have a built in hour meter. Some mathematical mind might even be able to give us a formula for average mph, or who knows? I wonder if a tech could tell by comparison if you had been idling (or sitting in traffic!) too much!



To check your hours: 1. Turn the key to the run position, but do not start the truck. 2. Push and HOLD the odometer/tripmeter button till it shows- hr ***. When the key is turned off or the truck is started it returns to normal mode. Come on, play my silly game!Oo.



My numbers: odometer-4905, hours-142.



Mathematical mind (yes, the wife) just told me my average speed was 34. 5 mph. I knew I needed to speed up! Divide the odometer reading by the hrs to get average mph. DUUUUHHHH

 

[Whitmore]

you had an average of 34. 5mph for 142 hours and the total milage was 4905 man you gotta speed that thing up or you will be killt from the behind



Cheers, Kevin

At last fill-up 7185mi @ 220hrs = 32. 7.



A few years ago I asked one of the Cummins reps (at a Cummins function) about the average mph on an eng. The stated was between 35 @ 40 miles per eng hour. If you gots more that this, then you running it and less means you dont have a life with your Cummins



Also, to get the hour meter to display you need to start with the miles not the trip odo.



SOTSU!!

At last fuel fill I had 11600 miles with 285 hours, an average speed of nearly 41 mph. At least I'm not the slowest one out there!

 

[Whitmore]

Man these 03's are slow just kiddin, another diff would be if ya drive alot of city vs. hiway... ... ..... lets get er up to the speed limit for your avg fellas



Cheers, Kevin

 

[goodwid]

I guess I am the slowest (so far)..... 14846 km or 9278 miles vs. 300hrs gives an average of 30. 93 mph.

 

[Greg Boardman-RIP]

Kevin,

Mine is a fast one

4000 miles/42. 5 hours=94. 1176... mph

Back in the pre-historic days... . I worked for International Harvester Co. , Ag. Eqpt. Division, the oil change interval on diesel powered farm tractors was generally at 100 or 150 hours. Using Ben's estimate of 35-40 MPH average in an hour, that figures out about right on the mileage.



Later, when selling heavy duty trucks (they all had electric hour meters), customers who operated with lots of PTO time pumping on/off loads, would ask about changing engine oil by the hour meter. The rule of thumb I gave was 300 hours assuming an average of 50 MPH. Normal condition recommended oil change on HD trucks at that time was 15,000 miles.

I do a bunch of non-interstate driving and when I am on the interstate I am often towing and not going much over 62-65 so I averaged out on the slow side:

6973 miles and 214 hours = 32. 584112 avg mph.

I will call it 32. 6 avg to make me feel like a speed demon .

[Swayse]

slow

17224 uncorrected miles. I've had 315s on since 800 miles. Using 9% to correct for tires=18702 divide by 595 hrs=31. 43 mph



Shoot, I though I'd be the slowest, with all the farm miles and idling I do.

 

[robobx]

27354 miles

693 hours



avg. speed 39. 471

And I even live in the "let's rebuild every road in the city at the same time so no one can go anywhere" Queen City



Must be that new EZ

Look at my post for Duty Cycle Monitor yesterday. If I can figure out how to get the photo attached, there is a bunch more cool stuff living in your ECM. Like total fuel used, idle hours, ave mpg etc.

 

[Brian-NX9O]

I keep a detailed spreadsheet of all the numbers the overhead can give me and the main odometer. Take a look at Brian-NX9O's 2003 RAM Mileage for the spreadsheet. All of the numbers in black are from the truck displays and all the blue numbers are calculated. I have posted some notes about the truck, how I use it and whether or not there is any load at Brian-NX9O's 2003 RAM Mileage Notes.



I will try to keep it up to date. PM me if you want a copy of the Excel file I made it from.



My Total Average MPH since new is 45. 8 as of 8,507 Total Miles.

Hmm, can't get it to work. With the key on to Run and I press the odometer button it jumps to the trip meter and resets itself. I tried some different combinations but no go. I held it for at least 10 seconds



I found out that holding the button and switching on the key cycles the gauge self-test. Pretty cool to watch.

[JD SLVR 03]

Hey Vaughn you need to start with it on the milage then push and hold. It will switch right away to the trip but just keep holding and it will finally tell you the hours. I found out the gauge cycle thing too while messing around with it... kinda cool!



Mine is at 6179 miles and 186 hours which = an average speed of 33. 22 mph

 

[Prairie Dog]

405 hrs / 14666 miles / 36. 2 mph avg. I'm surprised the speed isn't higher - It seems like 95% of my driving is on the freeway these days.

 

[Ladders]

If you think about it, for every minute you set at idle, that is 1 mile of travel @ 60mph soooo.....



Idle away and watch it go down rapidly or shut it off and not suffer on the avg speed. Also, if you watch your display and time it while at idle, it drops the mpg (on the y2k I had) about a tenth every 1. 5 mins or so. Havent got the exact figures and havent done it on the 03 (time the drop yet).





SOTSU!!

[WildWilly]

7885 miles / 226 hrs = 34. 889 I wonder if this would hold up in court as evidence for a speeding ticket

 

[dkok]

6680 miles/199 hours=33. 57 Thanks for the "heads up", I remember reading somewhere that it would have an hour meter but when I didn't see it displayed full time, I forgot about it.
