I think this was a topic recently, but would like to ask your opinion (can't find the previous thread)...

Has anyone tried converting their diesel 4x4 to a diesel/lpg mix? I've heard it works well with the vehicle gaining power as well as fuel economy, not to mention wallet economy.

Your thoughts?

If you are referring to LPG injection onto your already diesel vehicle then yes it is very viable and cost effective.

Best results are achieved from turbo diesel applications.

Upto 20% power and fuel saving but normally around 10%.

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
