The larger stations in towns, will have premium fuels but many of the smaller ones, roadhouses, etc. will only have regular unleaded, diesel, most will have propane, some will have furnace oil and/or kerosene. If you have the fuel range to run between towns you should be able to find all the premium you want. Or you may have to run an occasional tank of regular unleaded through your vehicle. For a couple of years when I had a BMW K1200 scooter, which called for premium gasoline, I finally became aware that there are at least two different ways of figuring octane ratings for gasoline. Europe and Asia tend to use a different method than does North America. Found that my BMW could use regular as it was the same octane as was called for using the German method of octane.
Or you could pack a couple of jugs of premium from station if you feel the need, unless your vehicle is a scooter and you don't have the room. LOL

"Without challenge, adventure is impossible".
We had pondered taking the Mercedes, and doing the hotel thing, but didn't think premium would be available, except for big towns. Now I would really like to know as well. I will have to pay really close attention when we gas up the TC on our trip to Alaska this year.
I am still deciding to take my Harley and tent camp or the truck/camper combo not both. The harley would be the cheaper adventure. The owners manual for the harley clearly states 91 octane but it is FI so one would think it would compensate. I just bought the bike so I have not had a chance to mess with it. The new one is a 2003 classic, the old a 92 dyna. My old harley called for 87 but always ran way better on 91. Thus the reason for the question.
The OP question IS very simple. If you don't know, don't jump in telling him he should not use premium or offer something off topic. As you can see I thinned it out a lot. Thanks to the couple that tried to help.

You will have no problem getting premium fuel at the larger centres - but many of the smaller towns or roadside stations will only have regular.
An Octane Booster is an easy way to get you past gas stations that do not have premium fuel. Looks like they run $4 - $5/bottle - you will pour one bottle in with your fill-up of regular gas. We went through at least a 1/2 dozen bottles, maybe a couple more, on our Alaska trip last year.
