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

Lean fuel mix or egr valve problems are the main cause off engine ping.
Is the egr valve working?
