Default Post your MPG

Not sure where to post this...

But we just drove our brand-new P-W Plateau TX (diesel) 500 miles and got 21 mpg. Quite a difference from the 10 mpg we were getting with our old B+.

I moved your post to a new topic - could be interesting.

------------------------------------------------------------------

That's great. I had a B+ (and a C) ....... I know the feeling.
17.2 mpg (U.S.) for my last tank. Diesel as well - '97 GMC 6.5L. Under 70 mph for the last two trips.

I noted the "(U.S.)" in your fuel economy. We should all try to post whether our gas mileage is
in US or Imperial gallons, as there is a measurable difference. Or, if everyone just added their
location to their Class B Forum profile (don't need addresses, just a general location like mine,
or even just Canada or USA or UK, etc.) we could probably figure it out intuitively?
Or we could do that confusing "litres/100 kilometres" nonsense that Stats Can uses.

I like the mpCg you use Mike.

Approx. 72% of visitors to this forum are from the US. 25% are from Canada. The UK and Australia are next.

L/100KM and KM/Liter don't mean much to me.

My last tank:
L/100KM: 13.7
KM/Liter: 7.3
MPG (Imperial): 20.6
MPG (US): 17.2

Agree about the L/100KM. I sometimes (when really bored) do a quick conversion to mpCg,
dividing the litres by 4.5 and round the 100km to 60 miles, in my head.
Hardly scientific, but it works.

We just got back from a relatively short trip in our Roadtrek C190P, 07, 6.0 litre. Big time winds at 30-40 mph. Headwind/20* crosswind going out and got 14.2mpg at 57 mph. Coming back tailwind/20* crosswind and got 20.0 at 57mph.

I just fueled up my 2011 PW Plateau Diesel Sprinter and according to my Gas Cubby App I only got 16.5 MPG for the last tank. Lower than I expected. I hadn't done a lot of highway driving during that tank and there were a lot of hills. My RV only has 4200 miles on it - is it still in it's "break in" phase?

This is only the 5th full tank of fuel I've put in and I don't have accurate data for some of the other fill ups...

Things like head/tail winds (noted in Booster's mileage post), hilly terrain, driving habits like cruising
speed and acceleration, tire inflation, weather conditions, altitude, and so on, all affect your mileage.
You'll get the best gas mileage when your vehicle is set up perfectly, driving at around 60 mph on
cruise control, on a flat freeway, with no wind or rain, at sea level (I'm joking).
If these fantasy driving conditions don't always happen when you travel, you'll get something less than
the maximum rated mpg for your vehicle.
I'd think your mileage seems pretty decent for that year/make/model.
See if it improves dramatically when you go on a longer freeway trip.

I agree, but our Chevy gets the very best mileage at 45ish mph Not a good way to make friends on the highways, but it will be close to 19mpg, if you can turn out the honking!

Just put on the 4-way flashers and hope for the best.
It's how we do it, when we're speed challenged when climbing grades > 7% in the mountains.
It gets scary when the rest of the traffic and the speeders fly up behind you and you're
wondering if (or praying?) they see your flashers.

I have a Savana Condo 2000, and I get 17 US MPG.

I though I would get more, but them's the breaks...

That's pretty good. What chassis and engine? Is it a Chevy Savana van? 5.7L V8?

I took the R/T 190V w/5.7L motor out yesterday. Camped in the Kaibab Nat'l Forest outside Williams last night at 7,000ft. Nice & Cool.
Drove 133 miles from gas fill-up yesterday to gas fill today. Took 12.00 gallons (US)!
That's 11.08mpg - yikes!
The van was not loaded - no water in tanks not much food on board, no passengers (I went alone).
I drove mostly between 60 & 65 mph. Slower on Forest road!
Only way I can figure is that it's ALL up hill from about 5,000 ft+/- to 7,000 with a long 6% grade on I-40 between Ashfork & Williams. Coming back (down hill) the wind was blowing - gusts to 40 mph on I-40 & head wind most of the time! ALSO I've increased tire size from 245/75-16 to 265/75. With previous (smaller) tires we had usually gotten between 14.5 to 16 p/g. Wind or no.
I'll test again but can't avoid the hills (it's where we live). Maybe the winds will die down.
But how much difference +or- do the larger tires make in MPG calculation vs. actual use??

That's bizarre. About a 30% mileage difference, 11 versus 15 mpg?
Hard to believe that it could be attributed to a combination of head winds, up hill drive, and
larger tire size, but who knows?
What brand and octane rating of gas were you using? I'm convinced I get slightly better mileage
on the 89 octane, than on 87 or lower. More bang for the buck? Probably just imagine it.
Did you check the parking brake? Maybe it was set.

In our 2011 Great West Van Legend Sprinter, a 170" wheelbase dually we are averaging for all driving over 24,000 miles now about 18.6 US mpg. If we drive 55 mph we will normally hit about 20 mpg. If we drive interstate speeds of 70 mph we will drop down to 17.5. The old I5 Sprinter diesel did not have as much variance between city and highway driving as the V6 does and our old 2005 Pleasure-way Plateau Sprinter diesel had an overall average of 22.5 mpg through 61,000 miles. Same drivers, same driving habits and quite a few of the same places for both vehicles.

If I keep complaining about this Chevrolet I just might have to look at a Sprinter. Lady across the street has an MB 5 cyl. I could probably buy. I helped her find it & it's hardly been used in nearly 2 years she has owned it. What a dilemma...
RE. Fuel - I always buy the cheapest/low grade I can find. Maybe a bad habit I learned from my Dad. He was a miser, but always had motor homes & nice cars. Next trip I'll kick it up & try the mid-grade, see if that helps.

It is a GMC Savana 1500, it is a six 4.3 liters.

Is it still pretty good??? May be I was expecting 20 MPG.. I know that the newer models (2011-12) have a better MPG. But I could not afford it.
