Flindersfan

I recently did an outback trip to Farina via the Flinders Ranges from Near Victor Harbor in South Australia a total of 750 km one way. I used around 1 tank (slightly less) of fuel each way so if my maths is correct 750km/80 litres is 10.67km/100 km or 22 miles a gallon. Fully loaded with a 1000 Lb of gear and 2 adults, Variable terrain, long distances at a constant speed of 50 mph. Oh and this is in a 1999.5 Pathy with 273000+ miles on it, 2 inch lift 2 cb antennas and RT tyres on stock alloy rims. A lot of fuel can be found by controlling the right foot.The most expensive place for fuel was Leigh Creek at $2.24.9 a litre or (Au to USA conversion) $5.90/gallon. I want to improve the ecomomy further somehow, but that is after a lot of rectification of neglection by the previous owner eg replaced the front struts with ome units because the old struts had zero pressure in them (withdrawing under own weight), at least the timing belt was done for me.
