exactly, i say keep it hush hush.
so just one more time...
you buy a diesel car, perhaps an old one rather than something newer, but not necessarily.
you run it nearly out of fuel, and then fill it with veggie oil that you have been stockpiling.
and then you keep on driving, completely as normal, for ever and ever, for about 40p per litre?
without having to make any conversion or incur any cost?
and if you run out of veggie you use diesel again for a bit?
and so it continues?
if so, then that is truly awesome!
is there a legality against running 100% oil? or do you have to have some kind of tax paid fuel in there aswell?
cheers!
