Thanks, Irwin,

I have to disagree with you on this one. I am using a rev. limit of 3,000
and for most of the time, the car rarely exceeds 2,000rpm. Nevertheless, the

My brother's '70 TR6 PI returned 27mpg driven fairly hard-before it was
fixed, its best shot was 12 mpg!

Of course, I respect your figures and stand to be corrected. I have a '74
road test of the 2.5S and the tester at 'Motor' got 22.2mpg overall and a
calculated 26.8mpg touring consumption. Bearing in mind that 'Motor's'
testers were known to hammer cars, I reckon that makes my car's consumption
heavy. Perhaps a contemporary test on the PI might shed some light on the
