I get better mpg on super vs regular.

Yup, 'tis true forIt is possible. On a vehicle with computer controlled timing and a knock sensor, the gas mileage will increase with more timing advance allowed by the high octane fuel.It could happen.
That would be false. You need to reread the rules and remember the discussion we had on this some time ago. Forum splits occur in threads that are NOT NEPRT, Off-Topic, or Jokes. This one was in a thread that was fairly well staying on topic.I think this is the new forum "black eye": getting your post split to "off-topic crap" from a NEPRT.
I think that only happens if the vehicle is designed to run on 91/93.It is possible. On a vehicle with computer controlled timing and a knock sensor, the gas mileage will increase with more timing advance allowed by the high octane fuel.It could happen.
Hey!!!!I think that only happens if the vehicle is designed to run on 91/93.It is possible. On a vehicle with computer controlled timing and a knock sensor, the gas mileage will increase with more timing advance allowed by the high octane fuel.It could happen.
if you run 87 you can get LESS MPG.......more if you run what the engine is designed to run.
If that was the case with the FJR I think Yamaha would recommend 91/93........but it's not recommended like some high performance sport bikes.
One thing I always wondered was why FORD could make their 5.0 V8 (like in the Mustang) be ok to run 87 but NISSAN said to use 91/93 in their 3.5 and 3.7 V-6...........and FORDS V8 made more HP.

Do try and keep it off topic ya klowns! We're having fun jimmykickin Carver here!
Correctamundo. Usually the engines that have knock sensors to back off ignition timing (and boost if forced induction) are the higher performance ones with high (effective) compression that the designers specify higher octane rated fuel. Even those do not always get worse mileage on the lower octane fuel, just limited maximum power output.I think that only happens if the vehicle is designed to run on 91/93.It is possible.

I suspect that the Ford 5.0 V8 is a relatively low compression, low rpm, large displacement engine compared to the Nissans. The smaller engines would need to use higher compression ratios and higher rpm to be in the same playground as an engine with 40% greater displacement. You know the old gear-head saying don't you? "There is nor replacement for displacement."One thing I always wondered was why FORD could make their 5.0 V8 (like in the Mustang) be ok to run 87 but NISSAN said to use 91/93 in their 3.5 and 3.7 V-6...........and FORDS V8 made more HP.
