I haven't noticed much of a difference but the ecu may be better at detecting the flavor of premium fuels.
For the record, the ECU in the S10 has no ability to detect anything about the fuel or adjust anything based on the fuel you use.

Around here the difference between mid grade and premium is like $0.10 and $0.20 between regular and premium. Fortunately I'm not that hard up that I can afford to fill up with premium. I mean we're talking about maybe one dollar more for a tank of premium vs regular. Yeah I think she's worth it. YMMV.

I mostly use Euro 95 here in Belgium (that's 91 AKI for you guys I think ?). Today I treated her with Euro 98 because I'm passing 10k km today :D
Euro 98 is 93-94 AKI I think.

We only have the choice between Euro95 and Euro98 here and that will cost you between 1,65 and 1,60€/l. That's 2$ per liter

For the first 6 months or so that I had the bike, I only ran 93 octane. Basically because the manual said so. Since then I have read some stuff here and there that made me think I really didnt "have to". So flash forward to the last month or so when 93 octane was ~$4.50 a gallon by my area and I decided to be cheap and run 87 octane for a few tanks.

I did not notice a significant reduction in mileage, or overall performance. However, I did start to notice that the off idle "stumble" or delay, or dead spot, whatever you want to call it seemed worse. I ran a few more times with 87 to confirm this feeling and then switched back to 93 octane. I can say that the off idle, very low end is definitely better with the 93 octane. It's been cold here, so I never worried about any knocking with the 87.

I think going forward when I want to be cheap, I will just go with 89 octane and as the temp warms up, will prolly stick with 93.

Mercy! Note to myself...stop bitchin' about the price of fuel; it could be worse.
Prices in The Netherlands are even a bit higher.
Max price of 1,884€ for Euro95 and 1,954 for Euro98. At currennt exchange rates that's 2,467 and 2,559 dollar per liter.

At the nearest pump here you pay 1,804€ per liter for Euro95. That's 2,36 dollar per liter. Welcome in Europe, where 1/6 of my paycheck goed to fuel for commuting to work :)

At $9-$9.75 per gallon in the US, there would literally be riots in the streets.
Even at $4/gallon, it's amazing to see how many people are turning to scooters OR are trying to ignore it and keep driving their huge honkers.
(Not counting work vehicles, where size may be needed.)

87 since day one. Although you would think in this day and age the other grades would have widespread availabilty I can tell that they are not. 87 is everywhere and the bike runs fine as did all the other bikes that were required to run higher grades.

YMMV

I decided that cetane beats octane, so have switched to diesel. Runs much better now.

8) No, but you can run diesel anytime you like, or kerosene, JP5/7, whatever.

I run Premium in all of my motorcycles, I don't care what it costs. I also don't care what the premium oil costs either.

True, true. Just recently stopped at a Shell station in Avon Park & they only have 87 because they do not have enough sales in the other two flavors to sell within their time parameters.

Wise guy remarks notwithstanding ( diesel and all that rot >:D ) I have a friend in the petrochemical business. He once asked what I ran in my motorcycles, and I told him premium. I forget now what started the conversation. I wanted to simplify the gas cans and such at the house at the time, and I picked premium. He remarked that that was a very good idea, skipping the octane part, due to the much improved additive package the more pricey fuel often has. Since I don't get 10-20 MPG with any of my motorcycles, I think the extra value is worth it to me. I'm also very close to sea level here, which makes quite a bit of difference. In colder weather (denser air= more O2 per volume unit of air), even my F150 pings on regular (87) under load in the mountains, so I tend to run at least 89 in it. And Ford specs 87 only in all of their vehicles.

Since Yamaha specs 91 minimum, I see no particularly good reason to second guess them, especially when I think premium is a good idea anyway. Mid summer, when the air is O2 deprived ( high humidity, less dense from the heat, etc) It probably doesn't matter as much. The O2 sensor resolves some of it, but not all of it, at least for my equipment. My WRR is very indignant if fed other grades than premium.

I know some of you mountain west riders don't have the same fuel grades available that we lowlanders do (can't call me a flatlander, as it isn't flat here) so you have to use what you have to use. I have the option, I choose premium.

Keep in mind I'm a sporadic rider: never commute, as I have to use the company vehicle. I don't ride intentionally in the rain or snow, nor when I'm fatigued. So the advantages to me for my fuel choices are less deposits, gummy gook and such during the times the bikes sit. I might feel differently if I rode every day, but due to a variety of things, I tend to be a weekend moto-goon for the most part. However, I often make up for the week on the weekend, so I suppose it evens out in the end. I had yesterday off, and the tenere went for a ride with our silly wind (30+ MPH with higher gusts) and today the WRR decided to go for a woods ride, and took me along. ::26::

Only Premium so far, but at these prices, the Tenere's going to have to give up the good stuff for awhile. Maybe I'll drop to mid-grade for a bit and see how it likes itl
On a recent trip I ran mid-grade for the first tankful, premium for the second tank - very similar conditions and riding style for both. Got 42 and 47 mpg. Seems to me that mileage is improved enough on Premium to make the cost difference between the two type a wash?
