Fuel Consumption on 100 Series petrol

[herks]

Just picked up an 02 100 series RV, 4.5 petrol. FZJ105R.

Must be the thirstiest truck I have ever driven. Have not worked out the actual usage yet but over 3/4 of a tank from Canberra to Sydney is a bit rich, 95l main.

Anybody any comments or ideas as to how to possibly get it sorted. Like a good mechanic who knows what he is about in western Sydney???

Thanks for advise etc.

Yes, they do use lots of fuel.
One of the guys at work has one and he normally gets 650km to the two tanks. By comparison the diesel with the same fuel capacity gets about 1150. You have alot more power but have to pay for it. Gas conversion??

anywhere from 17 - 22l/100km is normal. they are a big, heavy truck and the torque profile of the 1FZ-FE really doesn't suit the gearing, auto or manual. you can drive slower, but that won't make a lot of difference as you'll be picking between 4th/5th in the maual all the time or the auto will be in and out of lockup all the time. you don't mention if you have any accessories; roof rack, bullbar, lift, bigger tyres etc, these all have a detrimental effect on fuel consumption.

big 4Wd does not good economy make.

Like DD said - Very thirsty if loaded or driven hard.
That said - I feel they are very reliable and overengineered so are a good choice given their purchase price can be so low.

Expect 15-20L/100 as a best case range, and up to 30L/100 towing or sand 4WDing in the heat.

LPG conversion might possibly be a good idea for your situation, just get it tuned properly and get valve clearances checked regularly.

Yes this was a bit of a shock, moved over from a Nissan MK SWB SD33T and for an old rig was still getting around 11.5/100.

Noted the tip re a good tune, any ideas around western Sydney where the mechanic knows what he is about?

just run both tanks until the light came on and added 100 lits. drove till lights back on, 430Kms neat, that sucks but you are right about the grunt and pulling power of these rigs. Oh sorry its a 5 speed manual as well..

Bar, winch, roof racks and standard factory boots. 176 on the clock and never been off road (until I got her) that is.

Still *issed about the fuel economy though, oh well the price you pay for a good rig I suppose.

there is nothing to tune. the best you can do is change the oil, fresh spark plugs, pump up your tyres and drive it soft.

ditch the roof rack, it is costing you at least 1l/100km. possibly more.

which 'standard factory' boots does it have? the skinny 7.50/16's are best for economy, pumped up to around 50 - 60psi. lose the roof rack and learn to drive it economically, you can do a lot better than what you are getting.

Can't praise LPG enough. Over easter I used 2 tanks of gas, first one 96 litres second 98 litres and got 450k each time. The second larger fillup is due to the fact that you can use more of the gas up at slower speed as at hiway speed when it starts to struggle you switch to petrol, at slower speed you consume less so can suck the last little bit. BTW it cost about $60 something a time to fillup over here in the west. Gives me almost 1000k range too using both fuels. No noticeable power difference either. You're right, they're a good rig.
Cheers,
