Thanks for the post MGBGT.

I too have given up hoping the wife will improve FE in the Grand Caravan, she simply refuses to be consistant. Alas, my praise of her few good tanks isn't enough.

I don't believe any person's current FE statistics matters that much, as long as they are striving to do better.

On the other hand, I could have decided a long time ago that since the 70MPH freeway is the only practical way to go, all I can hope for is 50MPG.
Instead I took the time to seek out other routes and found a good one.
Another example is a light that is always red...I could have decided that I simply must stop, but with some looking I found a (Legal) way not to stop at all.

There are too many examples of choices to post here and everyone's situation is vastly different.....the only thing I'm encouraging here is experimentation.

I can't take for granted that I've done all that I can do until I've already done it.
If I think I've done it all- then do it over again with a different variation.

The 45.7MPG you've done in pipsqueak II probably isn't all that bad for your situation.....but I know you can do better...And you will.

Efficient drivers do it better.
