wow, u sure u driving a g35 and not a g20... i dont think anybody can manage 30mpg even if they get out of the car and push it

i basically average 15mpg a tank mostly highway but my speed range anywhere between 80-100

 

^our US friends commonly make the mistake of dropping in to this Canadian site without realizing the differences in size of our gallons etc.

 

^+1

Just for our American friends, our imperial gallon is about 1.2 the size of a US gallon.

 

actually, i'm using US gallons in my calcs. i've posted several times before on this topic as well. once in the summer after a road trip through the rockies where 30.1mpg was obtained.

many others have seen 30+ mpg highway mileage. is it possible that 6mt's are capable of better fuel economy than at's?

what do 5at's rev at hwy speeds? is there a significant diff between at & mt final drives?

 

Right on, some more examples

1 Imperial Gallon = 1.20 US Gallons = 4.546 litres

or a Mileage Example

24.02 Imp mpg = 20 US mpg

1 Imp mpg = .8326 US mpg

 

Really? US calculations here in Canada?

I've never seen any near 30.1 miles to the US gallon and can't recall others that do either, let alone "lots" of people that do. After conversion to Canadian that's better than the EPA rated 35 mpg highway by more than 1mpg. My fuel economy is consistently 30-31.75 on straight highway shots at 110-120km/hour which seems on the higher end of what I've compared to others. In mixed and mostly city I run only about 20 mpg or even less in my 6mt however.

The final drive in 6mt is different with shorter gearing final drive but taller 6th. IIRC, fifth gear is 1to 1 in both cars with the extra trans gear in the 6mt and the final drive differences make the 6mt rev lower at highway speeds. I forget the exact ratios.

 

^+1....
I find that extremely hard to swallow.

 

Unbelievable gas mileage, please, oh please teach us how to get mileage like that.
His gas mileage of 30 US mpg would be equal to 36 Imp mpg or 7.84 L/100km

 

Calculation please???

 

Yep, exactly. That's what I posted above. EPA is 35 or 8.1 l/km

If someone is doing that it's very respectable indeed. Maybe there is a loooonnnngggg downhill in BC with some heavy tailwinds.

RBull, GEE35X, InTgr: you posted several times in the thread i started (^) in which i detailed the observed 30+ mpg. some of you should check your posts in that thread for the inconsistencies in your responses to this thread. several members posted how they had seen 30+mpg as well.

please note that the initial title with "31 MPG" was incorrect, the actual number was 30.1 MPG.

and yes, US gallons in Canada is not unusual when comparing mpg calcs. it's similar to how most canadians know their height and weight in imperial and not in metric. as an engineer, i am well-versed in both SI and imperial units, but i couldn't tell you my height and weight in SI off the top of my head (i could make a close estimate). but i do know that i'm 6' 195lbs.

 

Sorry but I don't see any inconsistencies in the responses. It seems you aren't really claiming 36 imperial but 30.1 mpg/CDN and 26.8/mpg US according to the calculations Akrus did for us. If this is the case the rest of the replies appear to all be in agreement.

The confusion seems to come from mixing US measurements in a Canadian section. In my 32 years of driving you are the first Canadian I have ever heard of that uses US gallons in a fuel economy calculation other than someone converting from the US Nav/computer estimates. While I agree metric and imperial are universally interchanged in this country I just don't see Canadians doing that with US volumes.

 

Thats mine for this year.

You guys are doing way better than I am.

 

^^ RBull: in my previous thread i stated that i traveled 755kms on 59L of fuel, and that the low fuel light had not yet come on.

my calcs indicate that 30.1 US mpg was realized. i never calc'd using imp gal, but that would work out to 36.1 imp mpg.

when i calc mpg i use 3.785 L/gal (US). what is the CDN gal you refer to? i am only familiar with US & imp gallons.

 

Sorry Canuckle head I believe all 3 of us were consistent in our posts on that thread. Your location says you are from Canada so we naturally assumed you were quoting your mileage in Imp mpg as we quoted ours, not in US mpg.
