Fuel Economy - What do you get out of a tank? (3rd gens only)

[MitchellO]

With my revised driving style I got 12.3L/100km last tank. about 450km using 55L fuel, less than 100km motorway.

my KL is now (over)due for its 60,000km service (by nearly 2000km...)

my fuel econ from the gold coast up the Pacific hughway to bris (when reset before driving) gets down to 10.2l/100km avg.

im hoping that when i get my service done - fuel econ will improve a bit....

Unfortunately, still 13.3l/100km based on three fill-ups of different Shell fuels driving the same routes. I hope a tune-up can help improve on it further.

Replacing all three filters regularly (oil/air/fuel) as well as maintaining correct tyre pressures at all times will help achieve optimum economy.

Running a thicker oil will raise consumption considerably as well.

I recently upgraded to a TL .
My fuel economy has now improved to 12.5L per 100km (approx 550 per tank).
Country drive sat on 8.5L per 100km without even trying.

Big improvement over my 3.0L TE.

Last fill I managed 405ks from 46 litres - so that makes it 11.36l per 100ks and I had been flooring it.

Going to drive more conservatively this week and see how it goes.

Have only used V-Power and V-Power racing (yeah i know, bit of a wank but it was cheap that week) since changing Fuel Filter.

Weird I took out the fuel rail kit and although lost a bit of power my fuel efficency became much better. Laterly can go 600kms easily on city drive. I went country side driving and I was at 630kms with 20l left in the tank!

I also find my car runs best at 100km/h for best fuel economy as 110 km/h tends to take more fuel. If I do not overtake too often the car really goes well.

I found exactly the same thing on my car, not that I ever go above 100kph on the freeway anyway.

Funny you say that, my first week of driving my 3.0 on the freeway to work doing 90km/h my average usage was 9.8/100

Then the second week sitting at 100km/h it was 9.1!
