fuel consumption
Hi guys
I have a GU 4.2td that we use for pulling a Caravan which is 2 ton plus, the best i can get from the fuel consumption at the moment is 17.5 ltrs to 100kms, i need to improve this as we intend to travel round Oz next year i intend to fit a 3inch exhaust and turbo booster but will this help the fuel consuption the engine is in good condition burns no oil between services and does not blow out any smoke, i have looked into gas injecttion but was told it would not nececcarily improve fuel consumption would appreciate any help

A reputable diesel turning mob who know there stuff is a great place to start.... Do your exhaust & other mods first, then get it tuned properly by a pro.

LPG is a good option for more pulling power and a cleaner burn in the pistons , 60 cents a litre and turn it on when you need it cheers Alex

So your dragging a van that probably has a higher roof line that the patrol, causing excess wind resistance, then pulling the 2 tonne, usually up and down hills,inclines and your complaining about 17L/100Ks
Yes its a diesel and yes they are known for the economy, but you are towing a van non the less
My petrol GQ gets worse economy empty , no trailer and rolling down hills
Bigger exhaust and more boost should help , but i wouldnt expect a massive improvement

Hi Neil
I have 06 ute with canopy which is a bit higher than the cab (200mm) and have 3" exhaust with 15psi boost and dyno tuned. Power increased considerably and a lot better to drive usually in 1 gear higher than before tune up but no noticeable improvement in fuel economy. Presently 13.2 to 13.7 lt per 100klm with load on highway so I would guess 17.5 lt per 100klm is the best you will get with 2 tons behind you. I was getting high 11's to 12's before canopy and tune up but with the extra power available, you tend to use it.
cheers

i have looked into LPG and once spoke to a guy who fitted expensive conversions he told me improved fuel consumption would be negligible
-
thanks for that i would be happy with more power but like you say you tend to use it

Sounds like pretty reasonable fuel consumption to me.
If you spend a lot in mods to get slight gains in economy, you'll have to drive round Australia more than once to recoop your costs.
Hope you have a great trip.
