Firstly I wasn't sure where this topic belongs so if it is moved my apologies in advance.

I am looking to buy a el wagon 6 cyl with duel fuel.

It has done 300,000ks but been maintained by the owner.

It has a scuba lpg tank fitted but I don't know the brand of the lpg system.

Owner says the car with full tanks both petrol and gas return 800k's
but I think that isn't that great, I thought combined may see about 1000k's?

Well it's all going to depend on how much LPG it can carry and what sort of driving the owner does.

Picking number from your a*** isn't going to get you anywhere.

ive got a duel fuel setup in my EF II wagon and i get 420k just from gas on city driving with mixed throttle, havent done a full tank of petrol yet, but will soon

oh and i have 64L usable lpg tank
