...holding about 80mph (indicated* 90mph) with only half throttle??
And still getting 60+mpg (have even managed an indicated* 240-250 miles before hitting "reserve")
I must admit, my Ten's engine is quite loose now - to say the least!
I've done so many miles that it's hard to remember what it was like at the beginning.
Oh yeah, I remember; smoother & quieter (mechanically), supple suspension, err....cleaner!
