Re: engines and mileage
That's how I ran my old 84 Caprice that I had during the summer time.

Re: engines and mileage
For proper mpg checking, I suggest using a GPS to check your mileage. An odometer discrepency can cause over-confidence (I've learned this personally). No matter how perfect you think your tire/gear/trans speedo is setup, it may be off by a bit. And while it isn't much, it skews the data big time over long miles (which is what you usually go by for mpg).
