hey all, i was wondering, would changing gears while the revs r lower
decrease the amount of petrol your using? when im low on fuel im already in 5th gear when im going 60km/h. any advice and help? Sandro |

Re: fuel economy
It should increase your mileage, so long as when you shift to a higher gear
you are not opening the throttle more than you were in the lower gear in order to maintain the same speed. Also, avoid lugging the engine, as this will put tons of stress on your bearings and significantly decrease the life of the engine if done frequently. These torqueless wonders need to be shifted at a reasonably high RPM in order to not lug them (unless you are accelerating at a crawl... which is how you'll get the best mileage, actually). That is the nature of an engine with no torque to speak of.

Re: fuel economy
Too high RPM is generally defined as above the 'redline' for a particular
engine. That is to say, the max RPM that you are assured the parts in your engine will hold up to. I seriously doubt any Honda 4 banger has a redline below 5000 RPM. For best fuel mileage you should rpobably shift around 2,000 RPM (with a 4 banger anyway), for best performance you should probably shift at or somewhat below redline. Where you shift when desiring max performance depends on where your engine's power peaks. If it runs out of breath at 6000 RPM then shift there, but if it makes good power all the way up to a 7500 RPM redline shift at 7500 RPM.
