This tank was straight premium, though it STILL pings pretty good when I get off the interstate. Avg highway speed abt 61 (as has been most of this entire trip). New tires on front, but shifted weight to the trunk. last fill w. 5

93 oct to mix w. 89 (& bring up overall octane) so I don't ping after getting off the interstate 40 mi. of interstate on < 1/2 tank, so I'm not counting this as a regular fill-up unless the next is close to 35 mpg
