Thinking about buying a Landcruiser V8 ute. Will putting a bigger diameter exhaust about 3inch and extractors improve fuel economy and is there anything else to improve fuel economy.

Thanks

honestly if your thinking of buying a V8 diesel ute and worried about the fuel milage, dont buy it! Buy a suzuki mighty boy , you can spend upteen dollars on exhausts and chips for very little improvement in millage or just buy it and enjoy the power that comes with a V8 diesel and dont give the fuel milage another thought !!

Scoop, Jeff is right. The Toyota touted mileage figures are achievable as long as you keep the vehicle stock, don't tow and don't exceed 2000rpm. Anything over that, or anything you add to the vehicle will only increase the fuel consumption. Bullbar, wider tyres, extra weight through bigger fuel tanks, drawer systems, batteries etc or a roof rack and you'll see the kpl figures decrease.

I work my averages on 5 kpl (20 litres per 100k's) but that’s accessorised to the hilt, chipped, exhausted, big tyres and a whole lot of weight. As Jeff has said, if you’re worried about the fuel consumption figures, get a diesel six or a big 4.

yep the lads are right: with purchase price, insurance, depreciation, tyres, service costs and cost of mods etc fuel is the smallest component cost of ownership so is the least of your worries.

When I put the 3 in exhaust on my ute it made the fuel economy worse. I just could not resist putting the boot in to hear that sound. Hence worse economy.

If I kept my foot off the pedal I would achieve better economy.

Hope that helps.

I thought theyd get better than 5 kpl, bigger engines usually work easier.

FWIW
I average around 14-15 l/100k on the highway with my VDJ79, but that's running at around 90 km/h.

It totals around 3.5 tonne (large checkerplate box + Trayon slideon + spare wheel on roofrack) running on 33" KM2 muds.
(yes, it's been GVM'ed to 3.7 t)

3" exhaust & ChipIt chip.

Off-road low-range (eg Vic High Country) we can run in the 20-25 l/100k range.

I'm pretty happy with that!!

Scoop,

Maybe check out a diesel gas installation. Plenty of reports of improved fuel economy, provided you don't use the extra grunt, plus oil stays cleaner longer.
Just a thought.

Scoop,
I have a new '79 series LC single cab V8diesel 5 speed manual (just over 10k on the clock now), 2" lift, bull bar etc with canopy and gear on the back.

I put a 3" Beaudesert exhaust on it (@ 4k on the clock) (no chip - engine standard), and improved the fuel economy (measured prior to any mods including lift, canopy & extra weight) by 2 litres per 100km. So I am pretty happy. As above, it will depend on how you drive it.

Buy an older 6cyl Toyota, they get far better fuel economy than the new hitech fuel efficient V8. Toyota has progressed a great deal further backwards than some others.

............and is there anything else to improve fuel economy??

Yes there is.


A big block of wood placed under the "GO" pedal.


It makes a big difference.

It'll be a lot cheaper to buy!
