Remember that song from the 60's? I'm feeling it today. I've been code free for one week after my new turbo was installed last Thursday. I just got back from a little shopping at the Walmart and I decided to fill the tank since the price was ONLY $4.03 per gallon. Hand calculated - 19.06 mpg. No interstate driving this week, just 35-60 mph on the local roads, driving like a little old lady. I don't think the new turbo was the cause behind the good mileage but I'm pretty happy whatever the reason.
