Thread: Why has my fuel economy improved

3rd tank since the bizarre fuel economy improvement...

650km from the last tank full (no warning light) - long highway runs (5.5 hrs) at 100km/hr+ which would usually hammer the economy down. Put in 61 litres. Caltex diesel again, but this time from a different servo.

We just covered 6,800 km's with a fully loaded vehicle and roofrack with boxes etc and we varied between 10,4l/100 travelling mostly at 90km/h on road and 30 to 40km/h offroad and worst figure was 13,3 including soft sand and four persons.
Very impressed. Our manual states that 13l/100 as normal consumption if I remeber correctly.
We did note the combustion noise got worse the more remote we were and the dodgier the diesel. We had none of that low sulphur diesel at all.
Now that we are back on the low sulphur stuff she has gone quiet again.
