Adding Airtabs and switching to super singles. Mpg gain?
I just started using fuel gauges and over last 11,000 miles and 13 fill ups I am getting 7.7 miles per gallon. I run 54-55 on cruise and am adding Airtabs to just the tractor and switching from Bridgestone M720's to Michelin XDA Energy super singles. What kind of fuel mileage should I gain? Also I have Centramatics on steer axle should I get them on drives or something else?
Is this a good question?
