Drive slower on the highway (95 or less). Makes a big difference I found.
I've heard that hiclones can help but I'm pretty sceptical about em myself. Performance chip will definately help on a rig with a computer.
The 4.5L is a very thirsty beast though, regardless of what you do.
Did a test at tafe on the dyno with and without a hiclone hiclone dropped horsepower and L/km was up so they're a downgrade, If they worked manufacturers would install them

Jeez, what a load of it then. Where did you put the hiclone? I've had some bloke trying to convince me that putting one before a turbo on a diesel engine helps the turbo spool up faster for a quicker response and then one after the turbo aligns the air molecules for a better burn at the cylinders...Originally Posted by shaunh
The air molecule thing is what put me off. I kind of get how the turbo might possibly see some advantage out of it.
im about to buy a Fuel Saving Products but i was wondering if there is any recommendations here? any response please. thanks a lot.
What are you looking to buy?
the only fuel saver I’ve found is a garage/carport but you have to leave your car in it and you will save fuel guaranteed!!

Heres a few fuel saver tips
New 02 sensor or sensors as most ecu's these days will use these and other factors to adjust mixtures when cruising .
Make sure you have the correct thermostat critical to fuel consumption on any efi car is that the ecu gets to see the preset factory temp before it leans out.
I found most cars respond well to higher octane fuel like bp ultimate if everything else is working fine.
A few degrees timing advance can go a long way.
Cat converters can sometimes melt over and cause issues as well.
Afm clean.
A proper injector clean remove them and have them usltrasonically cleaned flow matched.
Probably a lot of other issues but all i can think of to ramble on with atm lol

Hiclone = snake Oil.
Best thing I ever got was a scangauge11 which work on the CRD. I believe there is a similar device that works on earlier Patrols. It's all in the right foot.
There is no point in a hiclone on a turbo as the air turbulence changes after going through the turbo most engines design your combustion chamber to help with swirl to get a good mix/burn the best thing for fuel consumption is a light foot small cube motors and not driving. Regular servicing and freeing up a restricted motor go a long way air intake and exhaust are the biggest factors here.
X2 that. and magnets also waste of money same principles apply.
would be oem if it was that simple.
How in the heck could hiclone affect this, it creates turbulence before the air filter.
It's something that interfears with volume and flow of air in take system.
design is that good these days, flow and the ability of cc's, is factored into the shape/design of head.
some turbulance may be required depending on the shape of combustion chamber.
but you will find only something as close as the valves area could possibly affect the chamber to aid mixture.
If Im wrong someone please explain it.
