dont forget, DGas & Diesel Gas were all the rage because you couldn't get a chip for the 3L, unless you imported them from Italy(and even then, it was for a 3L Fiat not a Patrol)

the early TD42 (like mine) works with the Gas as there is NO Computers in my Car, so even if I could get a chip for it (now they ARE available for the later models) it wouldnt work, as I dont have a computer run motor

as an example
- if I run my TD42 to and from work for a week - works out at 13.9L/100 - $60.00 diesel
- if I run my TD42 to and from work with the gas on for a week - works out at 12.5L/100 - $38.00 diesel & $12.00 gas

so its cheaper to run with the gas on, and I get better economy, and for a TD42, thats great economy
Basically what I said more suited to the 4.2 rather than the
3lt which are pretty much on limit out of the box
