It also might be an idea to remove roof racks , bull bars etc etc if you have any on..

If the car originally had an airdam , put it back on. The air dam on a RRC is supposedly worth 1MPG in the old currency.

Really? interesting, any more info?

Buy a pyro and boost gauge and fuel it up

Really? interesting, any more info?

No not really. It is a barely remembered line from a LR description of the 89 when AFAIR the air dam became standard equipment.

I have actually filled in all the slots in mine with nylon and added a brace to the steering protector so it doesn't fold back in water.

I did worse economy to Cape york this time without it than previous trips with, but there are too many variables to make any conclusions.

But air dams are supposed to reduce drag by decreasing the amount of air that goes under the car.
I also tried those wake disruptors but they didn't seem to do much.
Its hard to improve a shape that has a Rain Gutter over the windscreen and it is not practical to remove it . LOL

here is a quote from Ford's new Ranger press release which talks about the effect of their airdam.

Ford claims the imported aero gurus performed more than 1000 full-vehicle aerodynamic simulations to perfect the shape of Ranger for fuel efficiency, resulting in a deep front air dam and a small spoiler on the lip of the tailgate.

Mr Maertens, who supervises the aerodynamics team, said the biggest drag reduction came from the front air dam, which limits the amount of flow that goes under the vehicle and effectively cuts the drag by about seven per cent while improving vehicle stability and helping to cool the engine.

“A key challenge was managing the interactions between the air flowing over the roof and the variations of cargo boxes in the Ranger lineup, as this constitutes a significant proportion of the vehicle drag,” said Mr Maertens.

“The pickup’s ride height, especially in the 4x4 models, was another challenge. The higher the vehicle, the more aerodynamic drag it has to overcome. It’s a big number for every millimetre of ride height.”

Next time I am near my 87 RRC I will check in the owners handbook. It gives fuel use figures with and without the air dam. From memory they expect up to 10l per 100km with the air dam fitted at about 100 kph. I when I read that.

if you have a bit of coin to spare consider a diesel/gas injection. i've read good things about them improved power and torque, fuel economy and range.

on my list of things to do

Get an EL Falcon! Falcons are cheap, comfy and will do that speed all day.
