01ragtop Posted July 3, 2016 Share Posted July 3, 2016 My 2014 did 211 miles on 4.7 us gallons(almost 45 mpg). With only a half gallon remaining, I think that's as far as I would push it. This was mostly city commuting and going to job sites for work. Link to comment Share on other sites More sharing options...
jhenley17 Posted July 3, 2016 Share Posted July 3, 2016 I made it just over 220 miles on 4.7 gallons last week. My mileage has improved slightly since brand new. I have about 3200 miles now. Link to comment Share on other sites More sharing options...
Member Contributer fink Posted July 3, 2016 Member Contributer Share Posted July 3, 2016 4.7 US gallons is just under 18 litres have managed to get to 20 litres cant remember mileage as she was making progress but it was just below the 200 miles mark.

Greytec Posted July 3, 2016 Share Posted July 3, 2016 Today a 270 kilometer tour, quite slow... did 22 kilometers per liter. Link to comment Share on other sites More sharing options...
NZCam Posted July 3, 2016 Share Posted July 3, 2016 I'm one of those annoying types that records every refuel and crunches the stats, but in my defense, it makes tax-time a breeze, and helps identify potential mechanical problems affecting mileage early on. I'm also one of those annoying types that live in a country that uses the Metric system. :-p Avg Distance between refuels: 387 km Avg Fuel refill: 19.3 litres Avg Petrol Price: 133.7 cents per litre (AUD) Avg Refuel cost: $25.92 (AUD) Avg Kilometres travelled per litre: 19.88 km Avg Litres per 100km: 5.04 litres Best Litres per 100km: 4.49 litres Worst Litres per 100km: 5.44 litres Compared with 2007 Gen-6 VFR-800: Avg Kilometres travelled per litre: 15.93 km Avg Litres per 100km: 6.30 litres Best Litres per 100km: 5.29 litres Worst Litres per 100km: 7.62 litres Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted July 3, 2016 Member Contributer Share Posted July 3, 2016 Can easily travel 400k's before refuelling. And as NZCam shows, it most certainly has better economy than my three previous 6gens. Mostly run 91 octane. Link to comment Share on other sites More sharing options...

Member Contributer NodakVFR Posted July 4, 2016 Member Contributer Share Posted July 4, 2016 This is my best so far, and it took 4.8 gallons to fill the tank. I've been using 91 octane, non-ethanol fuel. Link to comment Share on other sites More sharing options...
RC79Scott Posted July 4, 2016 Share Posted July 4, 2016 When I reset the trip meter this morning I was at 48.5 MPG avg after about 500 miles since last reset. Always use 87 octane (and it would generally be E10 although I have a few "pure" stations around here, no E15 around here AFAIK). Link to comment Share on other sites More sharing options...
fatshoutybloke Posted July 4, 2016 Share Posted July 4, 2016 The furthest I've been before the last bar started flashing is 218 miles, but normally that happens any time after 190 miles. The furthest I've been after the last bar has started flashing to when I stopped for fuel was 30 miles (those weren't the same time). According to spritmonitor.de and fuelly.com it's averaging 53.3 MPG (UK gallons) on 'standard' unleaded which is 95 RON in the UK. Link to comment Share on other sites More sharing options...
Carlosfandango Posted July 4, 2016 Share Posted July 4, 2016 110 miles before my arse is squeeking and I have to stop for stand-up and walk around, so I might as well fill up. I managed 150 miles before stopping once but was wriggling around on the seat in agony. I don't have an iron butt like some of you guys. Link to comment Share on other sites More sharing options...
jhenley17 Posted July 4, 2016 Share Posted July 4, 2016 That's three or four days of commuting, not droning down the highway. I'd bet I could get over 250 miles on a tank cruising at 65 the whole time. Link to comment Share on other sites More sharing options...
gotpowr Posted July 7, 2016 Share Posted July 7, 2016 I routinely get 50+mpg on regular, 1/3 background 2/3 highway (but congested highway, so it's half 80+ and half stop and go). Usually fill up at 188 miles (1 day back and forth to work) for just over 3 gallons. Link to comment Share on other sites More sharing options...
barrypz Posted July 7, 2016 Share Posted July 7, 2016 Routinely get 55 ish mpg, sometimes better, sometimes worse. I can count on close to 60mpg touring though, and will routinely go past 200 miles before a gas stop. Link to comment Share on other sites More sharing options...
SlideRule Posted July 27, 2016 Share Posted July 27, 2016 With my 8th gen I routinely get 250+ miles per tank, sometimes on flash, sometimes not. I haven't tried to get 300 miles on a tank, always in too much of a hurry. Keep in mind, I commute on California freeways where its legal to lane split, so very little stop & go. My 6th gens showed 220 miles under similar conditions, with a bigger tank. Link to comment Share on other sites More sharing options...
CandyRedRC46 Posted July 27, 2016 Share Posted July 27, 2016 Looks like higher compression ratio and even milder cam/header tuning is really helping the efficiency on these eighth gens versus the old 6th gens. Link to comment Share on other sites More sharing options...

Well, I was going to say you were wrong on the changed compression ratio until I just looked it up. I would have been wrong. Didn't realize it increased a tad. My 2014 does get significantly better mileage than either my previous 5th or 6th gens. and still has plenty of giddy-up. I used to get as low as 38mpg when railing in the mountains and I have yet to get lower than 45 doing the same with the newish 8th gen. Ain't it just amazin' ?

Penny to a pound the fuel efficiency advancements for the 8th Gen vs the 6th (& 5th) Gen is down to advancements in the fuel injection/engine management systems. Honda persisted in making their own in house PGM_F1 system even though it was clear the specialist suppliers (especially the europeans like Bosch & Magneti Morelli) were generations down the track from where Honda was playing. Really would like any 8th owners who previously 6th owners to have a peep under the tank/airbox and see whats under there. Link to comment Share on other sites More sharing options...

Time for a part number search. I am willing to bet that the increased efficiency is strictly from the increase in compression plus milder intake cams, longer velocity stacks and more conservative exhaust design and mapping.

Indeed thats what I think, at least as far as the engine management systems go. Injectors? Nah. The 6th Gen was one of the first Euro3 compliant bikes, but that was a decade & a half ago. The 8th Gen is now Euro 4 compliant & much more fuel efficient in the real world as noted by others in this thread. Thats the worth of advances in engine management.

CandyRedRC46 Posted August 1, 2016 Share Posted August 1, 2016 Well the 2007 vs 2015 injectors are identical, same part number, so that's that....

Member Contributer Mohawk Posted August 1, 2016 Member Contributer Share Posted August 1, 2016 I think you'll find its a combination of the things CR has mentioned & that the bike is configured to run leaner everywhere. 45impg is not much of an improvement on 40mpg the 5/6th gens could manage. My CBR600F4 used to get 55mpg in similar riding. I believe the V4's have always run rich to aid with rear cylinder cooling, so they have always been inefficient compared to other bikes. Remember this engine was designed as the RC45, they tweaked it for the 6th gen, but its basically the same architecture, which means its over 20years in production already. Not bad if they managed to make it euro4 compliant, when most others have had to be scrapped or replaced with newer engines to pass euro4 ! I have averaged 38impg, for all the time I've had the bike, on my eurotour earlier this year on the gentle days it managed 41-42impg, but yesterday it did 160miles to the reserve bar started flashing, all of that was in the 80-90mph speed range. So its a speedy engine, I get 160miles on 50-65mph runs too, so no losses when going faster, unless its over 100mph, or lots of hard acceleration, like my track day a couple of weeks back that averaged 25impg !
