Hi All.
My Mazda (Baa) is currently in the top ten % list, although it's really only a seasonal visitor to those lofty heights.
Living in the Southern Hemisphere, while many folks on this site are experiencing cold weather droop, I'm getting my best figures.
By this time of the year, those figures are already starting to slide back to obscurity.
Baa's best mods are:
Mud flap and rear wing delete.
Taller than standard tyres.
Tyres at sidewall pressures.
Warm air intake.
Kill switch.
Vacuum gauge (must get an MPGuino!)
The greatest part of my success is driving style, combined with commute times and location.
I work a rotating shift, with start/finish times outside peak traffic load. This helps a lot.
I live in the Blue Mountains, outside Sydney, dropping about 600m going to work. This gives me plenty of opportunity to EoffC in daylight or EonC at night.
The climb home often has the engine operating at high(ish) loads which doesn't hurt that much when coupled with the previous EoC.
The second half of my commute to work is 110kph motorway which hurts FE, even though I stay at 90 – 100kph depending on the time.
On the rare occasions that I can stick to 80kph, my tank average improves.
