Patrol 4.2 Vs 3.0

Big Mike, I used to have a 3.0 and now have a 4.2 C/C.hassis so I might be able to help.

3.0 averaged around 11-12 l/100 highway and about 14 to 15 off-road (wagon)
4.2 averages around 14.5 highway and 13.2 to 13.5 off-road (Cab Chassis and Camper - weighs 3t).

Although the 3l went quick (especially with the dTronic), off idle torque was none existent. The 4.2 has it off idle (3" exhaust system fitted) and is by far the better vehicle off-road. The figures on paper just don't equate to real road/off-road feel.

I will not bag the 3l. It did what we wanted it to do and did it well - it just didn't last very long (115,000km's = shagged in the motor department, and a very long list of motor related parts failures).

The 4.2 is reknowned for its longevity, the EARLY 3 litres not so (ZD30).

But to answer your question as simple as possible, MY 4.2 fully loaded uses less dino fluid than my old ZD30 in the SAME conditions off-road (and it weighed a lot less, too!).

Off-Road / Towing = 4.2 litre
Highway / Light Touring = 3 litre

Just my 2 cents worth.

Best regards,

Craig.

Mike,
I concur with Craig as my experience matches his.

Cheers

anyone tells you they get less than 15ish litres per 100 they are on drugs. Best i ever got was 15.4 over 2000k's and thats with all the mods possible. turbo, exhaust etc.

Ive kept accurate stats on Fuel since my 4.2 was new.

Total Running average is 16.1L/100k (Including every type of driving & every drop of fuel used since new)

12.6L/100k is the best, is usually hovers around 13.5L/100k around town & general driving.

When Towing my Van I get usually around 18L/100k.

Last fuel fill up was 110.61lt & the distance was 799K's = 13.8L/100k

My GU 2006 cab/chassis uses 22 lt/10 km when fully loaded & towing our van (2.5t) at 95 km/hr.And I do mean fully loaded , dinghy atop etc....

Thanks to all for input.
Mike

Hi mate,

I have a 2004 3.0lt and haven't had any engine problems after 55,000km. From what I understand if you are looking at the second hand market, go a series III or IV.

I get around 12 - 13 lt/100km around town (13-14 with the muddies on) and on the black top and around 14 when 4wding. My economy goes up to 15lt/100km when towing my camper trailer (Kimberly Kamper) and sitting around 105km/hr). Overall it is pretty good but I must agree it is lacking a little before the turbo kicks in. I wouldn't want to tow a big van or anything, but a camper trailer is no problems

My mate has a 4.2 turbo cab and he is pretty happy as well but I believe his economy is slightly worse.

Hope this helps.

FWIW, my old 4.2TD used to average about 15.63L/100klm over it's lifetime with me. It was fairly heavy (3050kg).

I have a mate with a fairly standard 4.2TD who has recently fitted LPG injection. He just came back from a round trip Kadina Darwin Kadina (about 4000klm maybe?) and was towing his 20 foot caravan. Apart from a detour off the highway into Chambers Pillar, the van was being towed virtually all the time. His fuel economy (diesel only) was about 14.5 L/100.

Before he left for that trip, the fairly short distances he'd travelled since fitting the LPG and without towing, showed he was down to about 10.5L/100klm diesel. The amount of LPG he uses is negligible; about 30 litres per 1000klm (I think).

Hi Mike,
I have a very much modified Auto 02 3.0Di that has given me an average of 12.6 since the beginning of this year. Around town it’s in the low 11’s and towing the camper @ 100, around 14.5.
It’s now done 100,000k’s and since new I’ve only ever had to replace the drive belt because I noticed a few cracks, but other than that no problems and no turbo lag issues.
