4.8 Patrol on gas - problems !

who is doing the work?? A proper LPG place, a new fitter who has jumped on board since the new rebate to cash in, or just the local spanner man?

Gidday Truckster, It's the Nissan Dealer I bought it from new. They did the LPG install and every service. The install was done when I bought it 5 years ago, well before all the rebates etc.
Cheers mate.

Hi Sim,
I'm no expert on the subject. Sounds like all the items you have mentioned are on the exhasust side of the motor. For whaterver reason, sounds like you exhast gasses are to hot.
Could be as simple as mix rations - I think they usually test this with a sensor up the exhaust pipe while tuning.

Sim I do sympathise with you and hope that you find a solution. Got to take you to task over your brand loyalty though - how can you describe a vehicle that has given 2 years of poor performance followed by serious problems and a $10K repair bill as fantastic? You can expect 200K km troublefree from today's vehicles. Your experience as you describe it is a disgraceful performance by the vehicle and the service from its agents. You should be contacting Nissan's service and customer relations departments immediately.

Hi Sim

Sad story to here - but its not first time I've heard it.

Made the decision here to keep my 2002 4800 trim and stay with petrol
and I've been able to keep its long term fuel use to 16.5 lt/100km which is
tolerable.

"Lack of power get used to it" , what a statement I can imagine your concern
as performance is the reason to own these cars.

I have also heard good story as well so it seems to be in the quality of the setup.

I regularly monitor performance of my car , and any deviation is cause for concern.

Is yours an auto - they have extra cat sensors and are tricker - my manual does not have these.

When I did consider gas , my auto enginner brother who is well into this stuff advised the extra precaution of a seperate valve saver lube injection add on kit.

I guess you can't have your time over , but 10k extra certainly upsets the economy savings and it might be better to go back to petrol as per couple of others have done.

I have also made a little computer Oxy sensor monitor which sits on my car and it displays lean/rich etc. Mines a little complex - but you can get simpler after market kits.

You don't actually need the two oxy sensors - so if having problems in this area you can remove one and plug the hole, and wire the output of one into both ecu inputs, mines permanently this way. I sometimes use a Unichip which is great for gas , and they work by cutting and cross wiring the two senors.

Hi All, Thanks for your replys,

I should clarify that the $10K is an estimate including the warranty repairs, and based on the cost out of warranty which is probably $6K so far.

The car is great as far as off road capability, and drives like a sports car on the road. I'm very happy with that, but must admit that if I trade it, the D3 SE looks good. I wouldn't go with the gas again on a 4WD.

Cheers, Sim.
