series 60 mileage and speed
thought i would share my last few days of travel in our 02 newell. i have a series 60 with allison 6 speed.

tuesday my wife drove it for 200 miles at 55mph. we got 9.2mpg using the prodriver to measure it.

wednesday i drove 200 miles and the combined mileage between the two days of 400 miles was 8.5mpg. the first day was totally flat and today was some up and down hills. today i drove at 62mph in 6th gear running 1400 rpm.

at 55mph the allison stays in 5th gear at 1500 rpm.

that is the best mileage i have gotten the newell.

will be driving another 200 miles on friday and will see how it averages in.

what do you series 60 wanderlodges get?

btw, my first day of 300miles last week was in the 7's which included 160 miles of steep grades going from phoenix to winslow. up to 7600 feet and down.

later

RE: series 60 mileage and speed
You're running a much taller final drive than I am Tom. I'm running a 4:78 and I'm at 1555 rpm's on the S60 at 62 mph. If you're at 1400 rpm's at 62 that means you're running closer to a 4.30 final drive. That'll make a difference. I've been told by folks in the know that for the best S60 fuel economy to keep the rev's between 1450 and 1550 which is what I try to do. After 110,000 miles I see low 7's on my Prodriver which I've corroborated using the old fashion approach (and probably the most reliable approach) of measure miles and gallons pumped at the station and doing the manual calculations. After many thousands of miles and doing the paper approach I've seen some folks in the Prevost community (with the same vintage buses as ours) report closer to 8 mpg, but they're typically lighter than me. With your weight when you hit the serious hills you're bound to see a correction. If not, you gotta tell me where I can get the helium that you're pumping into your tires! ROTFL Smile

Tom,
FWIW I am geared like David, no slide, and two speed fan, not variable. I see low 6's on average and keep it at 62MPH . My last weight slip "loaded for bear" was 46,320lbs.Wink

In my 1995 with Series 60, I use SilverLeaf and it calculates mid-sixes with conservative driving, a bit better without the Jeep in tow.

Mid sixes on my LXi also. I've never been able to get over 7MPG in a LXi. Well, maybe once or twice on a 13 mile down slope.Big Grin

My ProDriver is usually in the 8s & 9s. I spent quite a while in dreamland before actually calculating mileage.

If I check the actual gallons used, it's in the low to mid 6MPG.

RE: series 60 mileage and speed
i will do some calculating to see if the prodriver is accurate or not. one of my newell buddies has done that it is correlates on his.

when i did the route from phoenix to winslow which is almost entirely up or down from 1100 feet to 7500 ft and backdown to 5000 feet, the mileage was awful.

last summer i calculated it and the entire 4k mile trip was in the low to mid 7's.

what isnt taken into account is running the genny either. we run the genny alot to keep it like an icebox inside.

but that should only be 1/2-3/4 gal per hour.

my rig weighs about 51k lbs.

RE: series 60 mileage and speed
My pro driver is TU but I have always logged all fuel in and all miles run (survival habit from my bush flying days). I averaged 6 to 6.2 mpg on my 96 bird with a series 60 and I average 6 to 6.4 with my 2003 LXI with a series 60. I always tow and load heavy.

This mileage is logged over a many thousands of miles and includes start up time, cool down time, aquahot and generator time. This is the actual mileage I use to plan trips.

Mileage minders (not singling out the pro driver), primarily in my diesel pickup experience, can be terrible liars. We bought a new 2009 GMC Duramax pickup, put in an aftermarket mileage computer, made two trips to Alaska and back and then put in the OEM computer and made the same trip to Alaska and back.

The after market mileage computer showed we were getting 3 mpg better mileage than the OEM computer. The logged fuel and mileage indicated exactly the same. Go figure!

RE: series 60 mileage and speed
I have been getting 7.5 over the past 35 k miles, over the past 8 months . like many I did not believe this possible so I have been checking the old fashion way and the results are the same . I did drop to 7.45 during a recent fuel issue but Pro Driver has me back at 7.50. Did hit 8.68 one trip even took a pic , had a tail wind I think lol

now my trips are mainly up and down the east cost on I 95 . I drive mostly 60 to 64 mph . I have only hit traffic a few times mostly in Was DC area . we pull a Chevy Trail Blazer .

RE: series 60 mileage and speed
i suspect you guys are right on the prodriver. from what i can tell i still believe i am getting in the hi 7's. for sure there is a huge difference between being in the tall mountains (i mean up to 8000 feet) than driving on the flatlands of texas and oklahoma.

all of these numbers are better than the 6 to 6.5 i got in my 90 newell with the 8v92. but....the 8v92 sounded alot better.....ha
