HEY! I drive like an old woman though, because it's too expensive to flog it. Always sit 5-10kms under the speed limit on highways etc... I might be a p plater but I'm also a tight ass!Originally Posted by DX grunt

My Gu running 14psi and 3/4 turn in on the fuel screw returns figures of about 12.5 to the 100 when towing our fifth wheel horsefloat goes to about the 15 mark. The GQ averages about the 13.5 to 14 mark but its a little more tweaked than the GU and is built for a purpose. Both are TD42's The GU has 255k on it and the GQ has 237k on it

Gu Patrol 4.8 manual, 3" lift, 285/75/16's returns between 16-17L per 100 if driven lightly. Recent trip from Brisbane to Kilcoy ( fuel stop before cruiser park ) loaded up with a 100L esky full of beer, 3 blokes weighing around 260kg combined, towing an offroad camper trailer loaded to the hilt with camping gear. Mostly highway but a small portion around town and through the hilly country roads used 22 Litres in 117kms which is 18.8L per 100

Do people find that a lift changes fuel economy at all?
Tappa tappa
Probably being a little higher might effect the patrols silky smooth aero dynamics and catch a little more wind. Lmao
tyre pressures effect the rolling resistance a fair bit.
Tap, crackle, pop
Hello from Under Down Under!
My Patrol is equally as aerodynamic as this
WOOPS sorry wrong pic, this is what I meant to post
Yeah I reckon it would have some impact, even if only very small. I was running 40psi on that trip as well
Some simple, easy to follow instructions on how to improve fuel consumption, mmmmm ?????

Instructions
1 Limit the amount of aftermarket accessorizing for your lifted pickup and/or try to be selective in the type of accessories you add. One of the benefits of jacking up a truck is the ability to fit larger tires and wheels. If possible, though, choose alloy or aluminum wheels rather than steel, as steel wheels will add unnecessary weight. Also avoid adding numerous exterior accessories, such as light bars, roll bars, step bars, winches, hitches or grille guards. Extremely large tires with off-road tread will also diminish fuel economy.
2 Drive your jacked-up truck at slower speeds when traveling on the highway. Because the truck sits higher off the ground, it encounters more air resistance and drag. This lack of aerodynamics hinders the truck's gas mileage at high speeds. Thus, driving the jacked-up truck at 55 mph or lower will help improve its efficiency.
3 Avoid using the truck's four-wheel drive whenever possible. Most lifted trucks are four-wheel-drive capable, whether it's at the push of a button or whether you have to lock in the manual hubs. Using four-wheel drive, however, comes at the cost of increased gas usage. Thus, switch over to using two-wheel drive any time you encounter good driving conditions. Four-wheel drive should only be utilized when it's absolutely necessary.
4 Avoid using your lifted pickup truck for daily errands or multiple, small trips. If you can, opt for a different, more economical household vehicle instead. This way, you'll save both money and gas. Use your jacked-up truck only when necessary or for recreational off-roading.
5 Check the tires and their alignment. First, make sure the tires are fully inflated. If they're underinflated, your truck will experience a loss in fuel economy. Also, if you've installed larger all-terrain or mud tires, you must make sure they're properly aligned by a professional. If the tires are out of line, you'll also experience diminished fuel mileage.

So my big girl has gone from just under 10 ltrs per 100k to about 11.5 ltrs per 100k.This only happened when i have put extractors and fitted a k&n air filter??has anyone else had similar dramas after makin their patrol breath a little better?????
You don't drive...you patrol!

Nope, in fact putting extractors on mine decreased fuel economy quite a bit, about 3L/100km, so it was a big difference.
I have a different engine though.
