There are alot of after market products for diesel engines.eg computer chip, valves etc
Does anyone know what may be available to improve the fuel economy and towing performance of a petrol 4.8ltr patrol.
cheers Trevor.

Hi Trevor
Trade it in on a 3 litre Prado will increase your towing and fuel economy however if you don't like that idea you will have to put up with the thirsty economy and average performance. Had the same problem with my 80 series cruiser and after changing to a diesel found that fuel economy and performance was much better but service costs went up considerably and reliability with injector problems and electronics leaves a lot to be desired.
The 4.8 Nissan is one of the most reliable vehicles on the market and you can tweak around the edges (and spend a lot of money) trying to improve economy and power but my view is to drive steady, keep speed down and enjoy the journey.

Have a good Xmas

Spot on
I prefer a diesel myself but what you have written is pretty close to the mark .
A lot of 4X4 owners spend to much time worrying about fuel consumption spending heaps of money on aftermarket gear that's gives them 1 or 2 litres per 100km better fuel figures .
The after market people just love these guys.

Cheers

What sort Trevor manual/auto year?

You can go from wild to mild.

One of ours generates 400kw and can take out our recently departed HSV Maloo mainly due to a 4" turbo system.

However my daily driver 2010 auto 4800 has had its towing performance improved simply by having the transmission reworked.

The manuals have an aftermarket computer option , Haltech , and this can be remapped with milder exhaust/breathing mods.

Unichips etc make little difference.

An aftermarket exhaust will make some difference but only at the cost of noise increase which is a compromize I am not prepared to do.

Nothing can make a real difference to fuel use though except keeping the standard tyres on as much as possible , i.e. not making the car worse with extra rotating mass and bullbars etc.

I can get down to 14lt/100km with careful driving and with petrol so cheap I don't worry to much but times will change I guess.

PS - have owned a 4.8 L as well as a 4.5L; driven both extensively through the arid interior. 13 years in two Patrols. Hard to beat the 4.8 for power & comfort.

Now driving a BT 50 which is also pretty good. Major savings on fuel helped pay for the swap from 4.8L Patrol to the Mazda 3.2 L diesel.
For example, in the 4.8 was getting approx 19- 22 L/100 km; same environs, same load in the BT 50 getting 13-15 L/100 km.

Cheers
