Rode 370 kms yesterday, occasionally in a "QUITE spirited" fashion... and got 54 mpgUS. (Gen 3 650).
overdue correction .... 2008 MOM states 87 octane min .... i believe i got 93 from the dealer, as I was meticulous in using premium during my first months of ownership, until i tested the waters with 87 octane ..... and the V ran fine with the lower octane .....2008 V and i believe the MOM says 93 octane. i started early on using 87 octane e10 and have noticed no change in performance nor gas mileage compared to 93 octane e10, no knocking. so that's what i've always run as it's cheaper. my gas lines look fine after approx 10 years. recently tried 87 octane e0 with no change in performance except worse gas mileage !!! very noticeable. it should have been the opposite.
I mean obviously 93 is better than 87 and may even give better mpg,
83 octane doesn't exist in a US gas pump. Regular unleaded in the rockies is 85 octane. I live at 6000ft and use mid-grade which up here is 87 or 88 octane. Ethanol free is hard to find here so I just run E10 with zero issue. Just replaced the spark plugs and they looked perfect even after almost 19k miles (lol @ the owners manual saying to replace them at 7.5k).Not the least bit of obvious there. The stuff that raises octane displaces the stuff that generates power. So you will get the best gas mileage from the lowest octane that your engine is built for. More money does not imply more better. Made for 87 = use 87. Up in the Rockies regular is 83 cause the air has less O2. That works fine.
I was curious about this so did some reading the other day. According to everything I could find you'll only see between 0.5 and 1.5 L left in the line based on hose length. Some articles even quoted Shell saying similar numbers.I've read (but haven't confirmed) that on modern "blender" fuel pumps there can be in excess of 4L / 1 gallon of previously dispensed fuel in the hose and lines. So, yes, on a vehicle with a small fuel tank, this will have a noticeable impact on the octane and/or ethanol content of the fuel delivered.
maybe that's why walmart has a separate hose for their E0 "real" gas. ethanol free afficionados wouldn't appreciate their fuel being adulterated by the previous guy's e10.I was curious about this so did some reading the other day.

depending on the ethanol content , that is hard to believe, energy in 87 and 89 is identical except possibly the ethanol content. 89 octane is slower burning and is designed for high compression engines. You want to see a significant difference, buy 87 octane, save your money until you have enough to get the ECU flashed , then you will see a significant difference and with 87Just wanted to chime in here, as I'm testing out my Gen 3 Versys. I've found that 89 produces substantially more power and a crisper throttle response than 87 (this is after factoring for variations in chain lube/tension and fueling mods).
I have a booster plug installed and | 87 - feels a bit under-powered | 89 - feels crisp and proper | 91/93 - have felt no additional power
