MPG is still not improving. Only all highway do I get 40mpg. My last fillup was 26.8 due to 50% city and short highway trips. It's also been 10F outside.
I got a set of acura fat fives 15" x 6 with 195/60/15. The speedo is now right verified with GPS. My planned mods for this weekend are installing a 192F thermostat and maybe bump the timing up. I filled up with premium this time. I don't think the engine is getting hot enough.
