So after my last challenge. I replaced the spark plugs with some brand new ones to factory spec
I did my trip to pick up my friend, drive to FITP and return my friend home after the show.
One mile before he got home I filled the ST up, dropped him off, grabbed my stuff and headed home, 93 miles later I was at the closest petrol station to home so topped the tank off so I wouldn't need to top it up for the rest of the month.
To my amazement I calculated I have done 59.16mpg!
550miles is achievable on one tank! 60+mpg is also avilable.
Bear in mind, I wasn't trying for this, I was taking a steady slow drive back and again it wasn't perfect as a run.
