I read a lot about petrol/LPG motors and people asking whats best. I once had a 95 4.6 HSE. on filling the tank, the trip computer said I had 253 miles on that full tank. The reality was more like 200 around town. I myself also asked all the questions about converting it to LPG and the guys in the know on here were around 30% for LPG and 70% against. I took their advise and left it as it was. After 6 months worth of gremlins kicking my ass around the car, I sold it!
I then bough a 98 2.5 diesel (BMW engine) RR On filling the tank on that one and setting the trip, it showed 610 miles to a full tank at 70 mph with the cruise control on. I realize this is probably optimistic and it wouldn't do that much in actual mileage, however the difference is unbelievable! Ok my diesel is a manual and doesnt have electric seats. But for near two and a half times the fuel economy, I can live with it. If your ok with spending the money on the petrol then up to you. If you have it converted to LPG it will cost around 2 grand. So in my evperence its even worh selling your petrol car and putting the money you would have spent on the LPG conversion and buy a diesel. To all the petrol owners please dont shoot me, Its just my experence of owning both petrol and a diesel.
