Filled up today. Came out to 22.34mpg

...?

Still can't figure out why it's doing this. Don't know that I ever will.

250 miles before it becomes a good idea to head towards the nearest watering hole would be really annoying if I had a commute to deal with.
Not a deal breaker, just a pocket book maimer.

Crazy loud valve tick now too when the car isn't fully warmed up. Don't know if it's just from trying Amsoil or if it's something more.

...old cars.
