Used Citgo 87 octane gas, Castol Syntech 5W-30 oil, no special effort to P&G but moderation in the pedal. Kept to the right lane with the flakes, Cell phone users and others . Moderate passes if they were too bad.

Air inlet temp was roughly 50 degrees Fahr (about 10 celsius). Mileage yielded on a 25 mile run (about 40 klicks). Scangage mileage was 41mpg).

On return trip (also 25 miles or 40 klicks) Air Inlet Temp was about 41 degrees Fahr (about 6 Celsius) and yielded about 38 mpg per Scangage.

Max speed was roughly sixty two miles per hour, a great reduction from my usual seventy to eighty mph. Resulting mileage improved considerably.

At no time was Defrost used.

There is a definite correlation between Air Inlet Temps and mileage. Need more data points for definitive conclusions.

Are you using Castrol Syntec Synthetic oil, or regular petrol based? Also, for best mileage (providing you've tried this), do you notice a difference if you keep the rpms below a certain level. Such as never accelerating over 3500/4000rpm?
