Yeah, here are my top tips to save fuel:
1) If you don't need to accelerate quickly off at a traffic lights, use LIGHT throttle and shift at 3000rpm in 1st, 2500 in 2nd, 2000 in 3rd, 4th and fifth. Don't use MEDIUM or HEAVY throttle and shift at 3000rpm in 1st, as that is just a waste of fuel It is not the rpm that consumes petrol, but the amount of throttle you give.

2) When you are going downhill, even a gentle down slope, use 5th gear (or 6th if it is downhill at 80km/h and above) and release the throttle. This closes the injectors, while still letting your speed stay roughly at that point.

3) When slowing down, DON'T shift to neutral or press the clutch. This not only takes away your opportunity to accelerate in an emergency, but also forces your engine to spray the injectors to maintain idle speed rather than fully close and rely on momentum to spin yoru engine.

4) When maintaining speed, use the ideal gear to keep at 2000-2500rpm with VERY light throttle. This activates the Exhaust Gas Recirculation (EGR) system and saves you fuel.

5) Other tips recommended such as driving closely behind another vehicle to cut through the wind and using neutral downhill do not save enough fuel to offset the additional risks you put yourself in. So it's not recommended to do those.
