$1.49  per litre  for 98 at the moment twb


the rip of bastards are buying it at half price out of malaysia  (tapis crude ) and still we only see a 20 cent a litre price drop ???

e10 unleaded cheapest we have seen in 10 years at 1.20 odd

wont last though ....our confidence restoring government has let the aussie fall to the lowest in 10 years also ...81 c us (and falling ) ....AND ...104 Nz ,,, (don't want to think what it is to the gb pound ...sigh ) crikey things are crook out here  and likely to get very much worse.

just a sign of the times I guess ,,, and our poor selection of representatives in government

Yep. Know how you feel. We are at an "all time low" today @  . . .$1.88 / litre
Wow. That won't last long. will be back up to 2.17 pretty soon methinks

Funny you should post this

Just out of interest I tried to see how far I could go in my Nissan 1500cc Wingroad, without pissing off too many motorists, at quite slow speeds, so, 70-80kph on the open road and 40 - 50 around town

Well . .  we managed 690ks on 45 litres = 6.52lts / /100k

The bike does 6.5

The difference is:


  • The bike will get ththe same economy as the car at lots of different speeds, from 100 - 200kph at times
  • The car is VERY relaxing and can transport 5 people and luggage
  • The car is Air Conditioned
  • The bike shaves 25% off the travel time (at least - up to 50%)
  • I am MUCH happier on the bike :-))


Guess it all comes down to what ya want out of life huh

Fuel consumption figs:

Riding Lismore - Lowana (thats up the hill to Ulong, so not all flat stuff (171kms)
K100RS - 100kph most of the time - 21.56kms per litre -equiv of 60.9mpg (imperial)  (4.638 l/100km)

Lismore -Grafton - then up across range on Gwydir Hwy (334kms)
100kph - 20.97kms per litre - equiv of 59.23mpg (imperial)       (4.768 l/100kms)

3000kms to Longreach trip. At 100kph was doing about 20kms per litre most of the time 

and some of the fills were that 91 with ethanol which i suspect delivers poorer economy than the straight 91 which you can still buy at the 2 BPs at lismore.

K75 T I had was doing 24 -25 kpl at same speed.

Did 108kms back fr Grafton on Sunday in 66mins. 100kph limit virtually all the way with double demerit points. AVG speed 98.18kph so Ii wasn't riding like Miss Daisy. If there was a space between any car and the double white line, it was mine.

You are more than likely right about that. We are stuck with the 91 ever since they banned leaded fuel. I remember when they did this to us. I was really annoyed. We went to unleaded first. That was a BIG mistake engine wise (prob good for the environment I don't know). I had an R100 at the time, 1979 model. Leaded 98 octane was the preferred juice and she ran like a rocket. Then we went to 95 unleaded. Lost the acceleration and the smoothness. :-((

Now K100 takes the 91 and with the improvement in horsey's over the R series I am ok with it

91 (straight) seems to be fine and when i did try 95 there was not a significant improvement in mpg, so I've just used 91 and there's no discernible drop off in performance.

Should not have used the words "I suspect" because it's a FACT. Ethanol has a lower calorific value so it MUST 
be accompanied by reduced power output.

Quite often I bypass places with cheaper E10 fuel (like Chinderah and BP 5kms north of Grafton) and just try and make it back to Lismore where there is straight 91. 

E10 is a con, one of whose greatest proponents was Howard, probably because his brother in law ran an ethanol production plant up north.

and 
one day I got 456 kms out of the K75T tank, not that it ran out but I just decided it might be a convenient time for a fill. I has intentions of riding quietly and seeing if i could get 500 but it was sold before this happened.

I've done 412 on the RS and will try for 450 on a double demerits point 2 week imposed period. Any bets?

Using 91 can cause detonation and that destroys the Nicasil lining in the bores. Leaves it full of pinholes and then it peels away.  If you have to use 91 then with ethanol is best as that helps prevent detonation but, of course there is a but, the ethanol will attack the rubber vibration damper round the pump and many of the other 30 year old rubbery bits in the fuel system.
I run 98 all the time and 95 if I cant get 98. I avoid the 91 and ethanol like plague. Any engine that has 10.2:1 compression wont run at its best using 91 and the K75 and K1100 have 11:1 compression.

The recommendations from Germany say 91 octane RON which translates to 86 octane here in the States. That's Regular grade; usually the least expensive at your local pump. Lift up your seat and read the black label there for your bike's fuel recommendation.

I did 7000 miles coast-to-coast and back last summer in a short period of time and I kept a mental log of the mpg and performance of my K75 during the trip using all different grades, brands, and ethanol content. The only gains I recognized were experienced using ethanol-free fuel. Octane didn't seem to matter at all.

My local pump offers 89 octane ethanol-free so that's what I usually use.

I wish that a low price on crude oil will shut down the tar sand and shale gas extraction for ever.
I don't want to start a political debate, but we are certainly not helping future generations to live in a clean world.

I am more in agreement with you perhaps than you think, that red maple leaf sure is a perty li'l thing. I mentioned political footballs - I know there are dark undercurrents to what the media harp on about and what the pollies and big business want us to think we know. It seems the (now Republican-controlled) congress of the US wish to override the President and the President wants to veto congress' decision on the issue of the XL pipeline, which, if you look at  it, will benefit Canadian oil companies quite well, but not do much for the US in general, but for the few states where oil extraction is happening along the proposed route. I don't pretend to have the answers. Hell, I took off the catalyst on my K12! I have some guilt. But I ride motorbikes (well-used, I hardly ever buy new) and don't own a car so I can get 45 - 50 miles per US gallon and take up less space on the roads, and used used parts whenever I can - that's one good form of recycling.

I do know that my daughter's generation and her children will be struggling to maintain things the way we've had it (pretty damn good in the Western world) without a more concerted effort on our generations' part.

Ride on!

Just sayin.............

BMW don't actually 'recommend' 91 octane RM (or RON). This is just the minimum octane rating suitable for the K engine according to the BMW Rider handbook
95 and 98 octane RM is designed for modern higher performance engines ie higher compression. 91 octane RN has a lower resistance to detonation... so +1 Rick
I've used 91, 95 and 98 on long runs and not found any appreciable difference in economy so now just stick with the 95

Ok,  I don't think that 'recommend' was the right word for him to use but as you said yourself "this is the minimum octane rating suitable" so this would suggest that engine damage was not envisaged.

I think that it would be better on 95 but i have as much of a problem handing money over to oil companies as i do giving it to banks. I'd rather spend the difference stopping and getting nice (more expensive) food.

just sayin...

and since the 75 is higher compression, I would give it 95..

Last year in France 88KE and myself encountered different types of petrol. I have done lots of travel in Europe but its all been in diesel cars and as they say diesel is diesel.

Generally in Ireland we get one grade and as far as I know its up to 10% ethanol but is not labelled accordingly. This is simply labelled 'unleaded' or 'sans plomb' in France.

Then in France there is petrol with 10% ethanol. This appears in France as E10.

But there is stuff over there which is mostly ethanol and is labelled E85 and my K does not like it.

I got stuck with using it at one point as it was the only petrol stocked and I was low. A significant performance drop and change in the engine. It has made me a little wary of motorway runs over there because as we know its easy to keep a K at 130km/h for ages....

Any thoughts on this issue?

What of these things?......... http://e85bioethanol.com/

Might be worth carrying a bottle of ethanol fuel treatment for those times when its all you can get. I've never used it so have no idea if they work.

btw... E85 in Oz is 87 octane RM. What about mixing 1/2 with 98

What we do is that if we get stuck and have to use the E85 then as soon as we can then top it off with the proper stuff by doing the next stop early. But the loss of power was significant and the increase in consumption was high. The octane rating is high, around 100 or 105, but the calorific value is lower and the ethanol eats everything.
