I was very ecouraged by how my car ran on the trip. I filled up with 93 Octane in Mill Hall PA along I-80 and filled up again on US 119 just south of Charleston W.VA and I got 28.3 MPG about 350 miles. That was on roads that were very hilly and curvy. Coming back I filled up again in Coburn VA. 93 octane gas down there was $2.559 a gallon on Sunday. I drove exactly 400 miles on I-81 to Chambersburg PA and got about 35 mpg. My jaw dropped
when I figured out my mileage. I guess driving on a straight road comapaired to hilly and curvy roads make a difference. The only trouble I had was when I was down there I went up into the hills on very sharp and steep hills going very slow and my engine got pretty hot about 235 deg and my fans were running. I just put in a new radiator and pulled the intake and supercharger for new gaskets. Would drilling a 1/8" hole in the 185 deg thermostat help? Around herewher I live if I'm sitting or driving slow it will get up to about 210 deg. Any suggestions?
