If I did the mental conversion properly, 150 miles works out to about 240 kms, & depending upon where/which way you are heading here in Aus, that can mean just over 2 hours of ryding.... some places even less.... Get out on the open road & 400 km between cities is generally just less than 4 hours of ryding at legal cruising speeds; but apart from Sydney to Canberra (major cities which are pretty close to each other) that's often not even half way there yet! Yeah, sure, there are times & places where you don't want to punt along like that, but this country is a big place with lotsa wide open spaces in between the major settled areas (well, except along the East Coast! People live in their neighbour's pockets there!) so ryding long distances becomes a necessity or you can die stuck between fuel stops! And it's really only the major routes that have fuel stops every couple of hundred kms! In about 2/3rds of this country, if you can't carry enough fuel & water to make the next stop then you are basically committing suicide to leave! :shocked: So maybe you can appreciate a little more about why getting better than 250km range is so important to me??
Oh, & just for what it's worth, & I understand YMMV, but I consistently get
better than 4km per litre MORE from each litre of Premium fuel than I get from std ULP - & my records include EVERY litre of fuel that's ever run thru my machine & every km it's ever travelled..... a machine which is tuned to run best on Premium! (Even more so now!) Sure, it
runs on the std UPL, just not so well nor as efficiently....
