I always use BP ultimate 98 generally from the same outlet but in some cases I can't.
So I was curious and there's probably few threads about it, but I feel like making a conversation out of it

So what's the most and your average?
I'm pretty happy with my efforts, I try to drive efficiently but sometimes mivec temps me and I give in

This is mostly around my town driving its not too traffic heavy and most times I get a clear run as its usually at 4:30 in the morning or 2-3 in the arvo. With a few trips down the coast and back.
