Need you help.

We have a 2000 Windstar; bought new; kept all maintenance up to date. It has 130,000 km ( about 81,200 miles ). I have changed plugs, wires, fuel filter, air filter, oil synthetic , tranny fluid, and coolant. All of this was done over the past 6 months and with OEM parts.

I have had poor gas milage for about 2 years now. I get 18 to 20 on the highway. I also get pinging when crusiing at highway speeds. My driving style is easy. I have noticed that when I burn Super gas, the pinging goes away; but the gas milage gets worse.

I need your help.

Thx
