Hi Darren, thanks for that, it's very helpful.

We are very busy, our vans are out there 6 days a week, all day. So as much as we would like to just switch straight over and do whatever it takes for the environmental aspect, it does need to be convenient and economic too.

That price of $1 per litre helps a great deal, that's the sort of thing that can go a long way to making it worthwhile.

I'll keep you updated on progress.
