Hi Davep, glad to hear you got your vxr sorted. Obviously being a higher spec motor it prefers the e5. My old girl seems to prefer the e10. As I mentioned in previous posts, it was splutters and sluggish for a bit, but a good service, and she seems happy again. Just recently did a trip of nearly 300 miles, and she returned 59.6 mpg, at a steady 60mph. I must be doing something right.
