Woo, I had my best fill yet with the car. This tank came in at 64.8 mpg!
The gain is mostly from not having to picking up a friend I bring to church once a week anymore. This trip was half interstate driving and that kills the mileage. Another factor is it might be a slight short fill. And yet another oddity was most of this tank was run with a faulty PCV valve. The engine must have swallowed the guts of the valve. You could see right through it. This caused a high idle and surging idle once it was warmed up.
I sure wonder what I'd be getting if I had full / good compression on the engine.
I'm really hoping to finish up the
rocker rust repair soon on the car and then shortly after that get
the electric water pump installed. With the cool season coming in, heat is much welcomed and I don't like to have the engine running to get heat.
