Mine was run on 95 when I brought it tried v power didn't seem to like burnt through it like no ones business. Tried Tesco 99 ran smoother and quicker and I get 345 miles to a tank in my 190 not sure how much is down to the decat and cobra when it comes to range but deffo get more miles on Tesco 99. Might run vpower with a few tanks. Deffo better for engine though my car had it's MOT with its cat off and it passed it's emissions and I'm sure it's down to the fuel.
