LPG & Diesel

Hi Matthew, I wonder if the best economy figures would be gained by the older style (pre-piezo injector). For my Wrangler I would need around 20-25% to make it a rational decision. Then combined with resale improvement it might be worth considering, but from a strictly economic point of view in my case , after the rebate, with exhaust mod it would cost around $2800.
If I left that in shares I would expect say $300 return which I would have to make up in the first year alone before I begin to make any saving.
I think you would need to be doing serious km's/year for it to make FINANCIAL sense. When you pull up at the pump and see say $1.75.9/L for diesel it can make EMOTIONAL sense.
This is without considering the increased weight/bulk/maintenance/ground clearance etc. I believe its brilliant for trucks and high mileage commuters but for me at <25K/year ...dubious......IMHO....cheers....silverback
