How Accurate?

[pdedse]

Pulled in to get gas with last bar blinking

It was showing 39 miles remaining



Toggled to B and it said I had gone 207.3 miles on this tank



toggled again it said I averaged 55.8 mpg on this tank



toggled again and it said I had used 3.7 gals gas



filled it up as normal to the bottom of the neck



turned around and checked the pump and I had put in 3.69 gallons of gas



With calculator 207.3 miles divided by 3.69 gals = 56.1 mpg (computer said 55.8)
Fuel pump said I filled up with 3.69 gallons of gas (computer said I used 3.7)

That's pretty darn accurate if you ask me

(still had approx .9 gallon of gas in the tank I am assuming for a 4.6 gallon tank or about 49 miles at 55 mpg... computer said 39 miles left)

This is so strange...I just got back from a ride and before I started I filled the tank and with calculator figured out I got 40mpg on my previous 96 miles. I thought to myself, "I'll bet The ferret uses the indicated mpg and that's why his is always so high". I was sure that Honda's indicated mpg was "generous" 'cause I had read an article that many car mpg readings were off by more than 10%. I was even going to pm Ferret just to ask about that, and then I see your post.

So question: I know there's lots of factors that can affect mpg. But let's assume that Ferrret and I ride pretty much the same. Let's say we have equally hilly areas. Let's assume also that we go for similar rides where speeds vary mostly from 45-60. Let's assume that we both have correct tire pressure. Is it normal for one CB1100 to get low 40 mpg and another to get low to mid 50mpg? I mean, that's about a 22-24% difference. I have a '17 EX and I had the '14 standard, both low 40mpg.

You guys getting 55mpg or more...please come visit, stay at my home a few days, eat my food, drink my beer, and let's ride and compare notes.
