I seem to have started something but the differences seems mainly due to the difference in uk and us gallons. Uk 4 gallons and us 4.8 per tank. Just filled up 210 miles 3.2 gallons 65 miles per gallon. Lawrance
😄😄😄I have been getting 60-65 MPG from my gt900 which is much better than the manufacturer claims I do use high grade fuel. Would be interested to know if anyone else is getting these figures
