Mileage to full tank of fuel

I have kept a pretty detailed account since getting my '22 Interceptor back in April. Fairly normal flat suburban conservative riding conditions (OK, so occasionally I will pass some cars that I really don't need to...). Averaging probably around 63'ish mpg. I did see a blip up in mileage after my first oil change. The weather was also getting warmer then but I recall the oil looking quite dark. I did not do any valve adjustment.

Any other comparative numbers out there? I really started this tracking first for the obvious reason of getting an idea of mileage and thus being able to predict how far I could go on a tank but then kept it going as a means of knowing whether I have some issue with the bike developing that might need my attention (i.e. if I start seeing a consistent drop in mpg).

I've played this game and commented before. I don't ride hard and deal in U.S. gallons. The fuel warning comes on at 194.8 miles and I put in 2.7 gallons. I consistently get 67 to 70 miles per gallon on long runs. I generally only do long runs of there to where and home in a single day. Each to their own.

Really….. 194 miles to a tank… not kms
Really. I live in a rural area with stop signs but few traffic lights and never stop and go traffic. A few miles out I am on second-tier highways. I am in fourth to sixth gears all the way at mostly 55 to 65 mph. Add in I burn 91 ethanol-free gas. All that and it is a magnificent engine and gearbox. I can't speak for any of the other platforms but in the Interceptor, that 648 cc engine as supplied is perfect. I don't need other pipes and filters and whatever, I just ride what I have and I get good mileage. It is early days but I don't know that I will ever part with this bike.

194.8 is not surprising at all particularly given @Woodstock 's usage profile. Most of my mileage is around town and suburban/country so rarely do I get to go more than 4 or 5 miles without a stop. The spreadsheet version of my data previously posted shows that on average I should be able to get 224 miles per tank. With a 3 sigma confidence factor if riding similarly to normal I have a 99.7% chance of not running out of fuel if I fuel up before 193.5 miles. As you can see I still rarely approach testing that in practice. Lately it has been more about when I am near a cheap gas station even with the great fuel efficiency of these machines. 😅7687

I got 63 MPG when I took a trip to Pensacola which came to about 140 miles round trip with mostly highway driving, but around town I'm in the low 50's.
