As long as you don't hammer it the SRT gets 18 which for the performance is not bad. My 5.2 liter get 18 to 20 back and forth to work and I've seen 25 on trips with the cruise set. I run at least 92 octane or better though.
Found and scanned a slide of my old Ford Escort Mk1 rally car from the early 1970s. This was taken not long after I'd fitted the wide wheel arches, and coach-painted the body with a brush. Still surprised at the excellent finish !
The wheels/tyres were a 'spare' set, and the roll cage hadn't been re-intsalled at this point. Boy, I miss that car !!
Far as I remember, it was called Royal Aircraft Blue, a synthetic enamel. I think I gave it two, maybe three coats with a soft coach-painting brush, and finished off with a clear gloss varnish top coat.
