I've never seen a pump that counted in gallons in the UK BTW

Actually I still need to do precise calculations for the whole trip, the odo is way off so I did a rough mental caculation.

I think I have 3.54 , or pretty close to that.  I'm also running 215/65-16 instead of the stock 195/75-14.  They actually put the speedo right on too.
