Pathfinder 1st Update

I've been running the Nissan Pathfinder 4.0 V6 Aventura now since mid May.

From My Cars

The first two weeks on petrol only to ensure all was well and then during a weeks holiday it was converted to LPG by Ray at Northern Autogas.
As with my previous vehicle, it's been fitted with a Prins VSI-LPG system. Just sneaking under the requirement for only a single reducer with the V6 running at just under 300BHP.
The first 1000 miles went very well before returning it to Ray for a visual and pressure check. A slight tweak to the static pressure and I was on my way.
During that initial 1000 miles I'd noticed a hesitation misfire on medium to hard acceleration and on some long hill climbs, particularly just after switching over to gas. That has improved but it's still there. I hope a further tweak to the pressure is all that's required but finding the time to get the vehicle back in to Uncle Ray is the biggest issue for me.
The performance of the Pathfinder is great. There is a noticeable change in the power delivery when on gas but with those sorts of figures it rarely presents itself as an issue of note in normal driving. Smoothness is improved and it runs a lot quieter. Considering the size of the aftermarket exhaust, this is a very good thing.
The increased tank capacity of the pathfinder, a 95 litre donut tank underslung in lieie of the spare wheel, gives a working capacity of 75 litres and a range of around 280 miles during the normal commute. This makes a big difference as I can pretty much do 3 days commute rather than in the previous vehicles' 2 days. I also makes the search for LPG Filling stations in unknown areas a lot easier.
With an average MPG of around 17 and Cost per mile at 16pence we're currently seeing equivalent running costs of a Diesel car that can do 41.5mpg as an average. Pretty damn good for a big 7-seater 4x4 with 300BHP.

the graph below shows the MPG since conversion. You can see the ping pong during the early fill ups as the pressure system balances out but since then it's been a lot more consistent than the Outlander used to be.
