Outer Limits 4x4 Board

yes fuel is starting to help. Does anyone know of some good ways to get great economy our of 2h 60 series diesel? Hoping not to have to spend the $ ona turbo.

I think the economy isn't that bad I can get 600kms+ to 85L. Some people say extractors and new exhaust help, some say they don't. I picked up my extractors yesterday and the exhaust will come soon enough. The turbo would only make the fuel econ. worse wouldn't it? Also taking off a bit slower at lights and maybe looking at your driving technique may help to reduce the fuel econ.

I get roughly 12 - 14L/100Km or about 7km/L.

Certainly alot better than a 2F.

Yeh trying to drive heaps smooth. Im getting about 12l/100. Still hpinh there might be a way to get it to about 10. Keeps the hand brake happy. She makes me drive her little girls car all the time to save money. Hope your new exhausts helps.

Me too! I would love 10 as well!

the economy of a 2h is very good, given the weight of the car If you're not happy, and fuel prices are hurting, then you should either look at making the truck lighter (loose bull bar, spare tyre, run narrow tyres), or buy something that will give better economy.

a properly set up turbo will give better mileage. the reason it doesn't for most people is because they drive harder when theres more power.


you'll never get 10l/100k out of a 2h, but you can always dream (or buy... a LAND ROVER!! )

Have you guys thought about manufacturing your own biodiesel? Think it works out to aboout 20c/Litre. Bit of work though I think. Just a thought.

Would either of those too, especially the spare make enough difference to see a drop in fuel econ? I wouldn't think so but I would loved to be proved wrong!

Is that so, I thought is was because that the motor was working more. < insert comment from carts here>

Not funny

Joel you're scaring me!!!

Well, when i first turboed my landcruiser, 8psi, slightly modded fuel characteristics, it did improve my fuel economy. I was getting around 11l/100km's with a mixture of town and country driving. Just taking it easy.

HJ60_HEATHUS is right in saying what he did. Most people abuse the use of extra power, thus use extra fuel. But a properly set up turbo will make a diesel more efficient. After all, the turbo uses waste exhaust gas/heat to create forced induction into the motor.

A few tips for saving fuel on the 2h. When highway driving, settle for sitting on 90-95km/h. It is an easily attainable speed for the 2h. Pushing it to 100-110km/h uses heaps more fuel and surprisingly requires a lot more effort. Around town, try and maintain gear changes under 2500rpm. When you rev these motors over 3 grand, at night you can see all the extra fuel going out the exhaust as smoke!

Thats my comments Joel...hope that helps Ads...in the long run, turbo will yield more power for the same economy if driven right. And it certainly helps on Stockton Beach.

well it all adds up, but it is only likely to be a minor difference.

good advice. about the gear changes, it sounds reasonable for a turbo'd 2h, as there is likely to be better performance in the 1500-2000rpm range, where a gear change will leave you. I've noticed on the na 2h, (keeping in mind torque peaks at something like 2200) that pushing the motor to 3000 leaves you better off, speed and economy wise, as it keeps you closer to the top of the torque curve.

unfortunately the h55f doesn't do the 2h any justice, given the massive leaps between gears

in addition to sticking to 90-95, i'd also say, drop back to 4th gear when hitting a hill (more so if you're running the wider tyres), keeping the revs up, and getting more air in.

My Canadian HJ60 has been averaging 10.5L/100km, roughly 700km per 75 litres.

Weight is one issue, but so is drag. As stated, SLOW DOWN (pretty easy in a 2H ). Years ago there was a caravanners rule that 5MPH=5MPG. Is still fairly accurate today.

Lose all the dags hanging off the vehicle. Bars, racks, even aerials. Lose excess weight and pump your tyres up hard.

A PROPER tune up is expensive, but will help a lot. Just throwing in 'new' injectors often doesn't help as they can come out of the packet with woeful spray patterns. You can also get the pump 'turned down' for better economy, but you will lose a bit of oomph.

What's involved in a PROPER tune up? I have had my 60 down to as low as 10.5L/100 and near 9km/L.

Just thought i'd add my two cents- i have a HJ 61 and i get 10k/l on long trips, around 8k/l in town. so there's your solution- drop a 12HT in (:
