This has been done over so many times I'm surprised people still get it wrong. Not true Willem. There will be increases but not to that extent. LPG will remain the cheapest fuel.

Well Ray, seeing as you say I am wrong, how about a full explanation?

I would also like to add that who the hell knows what will happen in 2007?
No one predicted the rise in oil prices.

If you can afford it Shane, I say go for it. V6's can be thirsty as in a 4by.
If you do, and has been said already, spend the money on good valves and valve seats cos some standard ones can't handle the higher combustion temperatures and will burn away eventually. Just do some research by asking LPG fitters and mechanics about your engine.
I bought a V6 Rodeo on gas and I dont regret it now with the absurd petrol prices.
I was lucky though, the previous owner had to get the heads redone (70K ago) with proper LPG valves and seats etc. for above reasons, so I'm looking at getting quite a few miles before any valve troubles.
Make sure you run it on petrol regularly too to keep the injection side of things excersized. It doesnt have to be for long periods, just to keep things moving.

Willem, sorry was in a bit of a rush before. The Commonwealth Government has announced that excise will apply to LPG. It will be increased annually from 1 July 2011 at a rate of 2.5 cpl increasing to 12.5cpl by July 2015.

It was originally planned to start in 2008 but they backed away from that date till 2011. They are likey to back away more after worldwide condemnation.

Even at 12.5cpl tax it's a lot cheaper than petrol and diesel and the gap will probably increase over the years.

Oh yeah, they will also be offering a $1000 rebate on installation when the excise cuts in.

Yep who knows, as they say only two things in life are certain but at the moment that's the plan and failing to plan is planning to fail :)

keep chugging

The Toyota v6 engine in the 4 runner isnt a great choice for lpg as the cyl heads will require work how long i dont know if it has low ks you may get 50-80 k more out of it .
Although once the heads are rebuilt with better valve seats etc it should be fine for years .The biggest drama ive found is the tappet clearance tightens up because of valve recession and being a bucket and shim type lifter are expensive to get adjusted most people dont do them as required and they then burn valves out ..

Just remember taxis aren't on lpg because it cost them more. In NSW it is 85cents cheaper. Surely that outways the cost of a possible yet unlikely repair.

Yes it depends on the engine. I did over 300,000 K's in a VL commodore on gas. Took me around Oz on the blacktop with never a problem. Still operating perfectly when sold.
