OMG 4.8 ltr fuel consumption

[LPG IQ]

This is an enclosed air box and will be able to connect to a snorkel.

The Dyno operator has said the gain is both air intake improvment and the fact that it now looks at different areas of the timing maps in the cars ECU.

Ok, last tank before new converter install i got a little over 2km/L city driving... Insane. Hoping for better now, LPG guy is confident.

I did the Madigan line through the Simpson 2 years ago with a few mates.
One of the guys had a 4.8 Patrol and had 345L with him when we left Mt Dare and ran out of fuel at Big Red.
We did have a lot of detours around flooding but was over double what a diesel Hilux used.

I'm feeling your pain brother, my 4500 drinks the fuel like its going out of fashion.
But, I do tow at highway speeds and pass just about everything in sight!
Not a lead foot, just need to get to where I'm going to in the shortest time possible!

I had a 4800 a few years back, it was better on fuel than my 4500 by far!

My 4500 uses 16ltr per 100k's on lpg and 20ltr per 100k's on petrol.

Either way it costs an arm and a leg to run.

*sigh* I've kept consumption figures for my rig since I got it.

My 4500 uses 30ltr per 100k's on lpg, more in low range. Always has. Two seperate lpg mechanics, two different dynos, regular service. Always told "yep, all good". Plugs and leads, the lot. I can tell when it needs a tune, economy improves and idle is rough.

When I ask about improving fuel economy I get told "Not much, they're thirsty buggers" and aftermarket ignition timing chips are "a waste of time" as it's mostly a mechanical system. I've got a mate with a 4800 and he gets about the same as me but with lpg vapour injection. When I asked about going to injection, "yeah ...sure, won't help much and $300 per injector + fit".

I read these consumption/economy threads front to back and try to follow any leads. Bigfella isn't the only one reporting figures I dream of and I wish I could pick the difference. Any ideas?
