G'day All,
I have recently purchased a 98 100 series cruiser petrol.

I noticed the fuel economy is crap, I thought here was a problem so for the past 2 months I have consistantly put 15 litres into the sub tank and ran it dry to see what I would get.

The result is 60-65kms to 15 litres around town, no heavy driving and very little stop starting involved, so I assumed the economy would have been reasonable.

This equates to 23 litres/100km.

Now I know petrol 4WDs are thirsty, Ive owned a few, but this result is not what I expected.
The motor has 180000 on the clock, but has been looked after and I have just had the motor serviced.

My question is, are any of you 100 series petrol owners getting the same?

Might be time for a diesel.
Thanks in advance.
Regards
Brendan

That does seems a bit high for normal driving, I get around 19/100 in the Nissan. Is yours full time 4x4?

my 98 4.5 petrol was giving around 22l/100 (13.5mpg) and i had a heavy foot
my newly aquired gives 13.6 (22.5mpg)...its a diesel, but the extra cost for the diesel engine buys a lot of petrol

It may buy a lot of fuel, but for every dollar spent on a diesel engine, you get it back on resale. The other thing, you can sell it easily as a private sale and command top dollar. Unless you have money to burn these days, you couldnt even consider a petrol engine pushing around 2.5 tonne. !!

But you must have the money to burn if you have the extra money to buy the diesel :)

Brewman!! i meant buying a new petrol vehicle now!! But is really is pay now or pay later. with a diesel is pay now and save from now on and much better resale.. LPG is ok if in town but it takes up petrol tank capacity. Not a lot of good outback. Diesel is the way to go in the future. What i cant understand is why diesel engines are so expensive! The 3 litre patrol is the same price as the petrol and the 4.2 is $10 grand more. So it is an extra 20% of the cost of the 3 litre, doesn't add up for just two more cylinders. Anyway, thats my opinion for what its worth..... Michael

The 98 model is a 4 speed auto gearbox and when it was designed fuel economy wasn't an issue because of the price of fuel. The latter models have a 5 speed auto and apparently deliver better fuel economy. The mileage shouldn't be an issue but make sure the state of tune is correct. I here of all sorts of stories about people servicing these vehicles that use the wrong plugs etc.

Otherwise these are big heavy vehicles and the diesel models are the way to go if you are concerned about fuel.

Slow down and relax......

Brendan,

Mine's a 98 4.5 100 series petrol model too. Like you, I was expecting a bit of a thirst but it's worse than I expected. I reckon 22/100 around town. That's Sydney. I'd be a bit worried if "around town" was Dubbo or similar. I put LPG on in April 05. $2300, which is pretty good (they charge another $1000 for a Patrol) and I reckon I'll break even within the next four weeks and that's on average(ish) mileage. It's nice to fill up for less than $40. You use between 15 - 20% more fuel. So, @ 50c p/litre (I get mine a bit cheaper) add 20% which makes it equiv 60c per litre. Still well under half price. Have a phone around there are a couple of ways of doing it. I went for removing the sub-tank and spare wheel and got a 90L LPG tank to go with the 90L petrol tank. Then you've gotta find a home for your spare wheel. Either grap a rear wheel carrier or a cargo barrier to strap it to.

earlier posting was right the old 6 cyl 100 series has always been a bit of a shocker on fuel. The V8s with the 5 speed auto box though only slightly better on power are a lot better on fuel. get around 15 - 16ll per100 average city/country
