MPG. What do you get?

[Doctor T]

Not sure how accurate the average mpg reading on the dash is but my last tank gave me an overall mileage of 58 miles per UK gallon. This is for mixed stop/start traffic and for motorway runs. After 3 tankfuls it's telling me between 56-58 per gallon. Not sure if this will increase/decrease on a long motorway trip.
Is my MPG around the same as you get?.
Compared with my RE Himalayan which gives around 85 mpg with the best being 93 mph. But that is a lower performance, lighter bike. So like chalk and cheese

I get just over 60mpg on my 2021 - mixed country road riding mostly.

I guess y'all are talking Imperial gallons. I am averaging 42 miles on US premium
But, I am not exactly Mile Milling either.

My ‘15 gets high-50’s low-60’s (U.S.)

Looking back at this thread, BMW R1200RT / R1250RT forum - The BMW R1200RT/R1250RT forum my worst and best MPG has been 42.0 and 67.4.

These are physical checks from full to full tank with imperial gallons. The onboard BC is usually fairly accurate.

I usually get around 55 to 58 mpg in day to day riding.

So looks like am hitting the average. Cheers for the replies chaps

Do you run your bikes on premium or standard fuel?. My local supermarket petrol station only sells standard E10 and if i want premium i have to ride an extra 8 miles to the next station. I've read the bike prefers premium but will standard affect the performance? 

[David.]

I run both my bikes on the higher octane E5 fuel, usually Tesco Momentum 99 (E5).

The "official" BMW line recommends what they refer to as Premium plus unleaded 98 RON.

Alternatively, Premium unleaded (slight power and consumption related restrictions) 95 RON.

I'd be very surprised if you can feel any difference in performance between the two fuel grades.

However, if you are looking at MPG, then yes, higher octane (E5) and non-supermarket fuel may give better results.

Have done a comparison between Tesco & BP (both highest octane rating) fuel over the same 100 miles with the cruise control set at 70 MPH.
Returned 59.9 MPG & 64.6 MPG respectively, using the physical full to full method.

E10 95 RON for me. I have noticed a slight drop in mpg since it changed from E5 95 RON but not enough to warrant paying for the premium grade fuel. Same with the car too.

[Steve398]

Absolutely no chance of buying premium for every fill up, I tend to do one in four, which I read somewhere suffices to keep the injectors clean, otherwise standard cooking sherry 95 for me.


In answer to the post - 54mpg

I have averaged 60 to 64 mpg (same method as David) for my 2020 R1250RT, over the 9500 that it has done.  A good mix of road types, from town stop/start to motorway cruise control.  I do tend (!) to stick to speed limits.  On board display says 62.8 mpg, overall, so looks about right.  I always use "super" juice, E5 whether from a supermarket chain or one of the "big brands".

I did a trip to Oxford and back home this morning. A 220 mile round trip in total. This is 95% motorway and dual carriageway. A27, M27, A34, and a bit on the A40 only using the cruise control on clear bits set at 73 mph. Panniers and top box fitted but little in them. I wanted to see how the wind affected the bike before my summer European tour in the summer. I did notice a slight wobbly after a certain unmentioned speed but nothing dangerous.
Anyway, the bike computer averaged 59mpg. My maths calculated the true was 58mpg on premium fuel.  Just out of interest the bike is a 2007 model with 42000 miles on the clock and am a shot fat, hairy git. For a heavy bike am happy with 58mpg
