In the 2015 owners manual on page 5-38 and 5-39 there is a chart with recommended up shift speeds for "the best fuel economy and performance in using your manual transaxle".

They are as follows:

Acceleration conditions:
1st to 2nd- 15mph
2nd to 3rd- 28mph
3rd to 4th- 36mph
4th to 5th-45mph

Under cruise conditions:
1st to 2nd- 15mph
2nd to 3rd- 19mph
3rd to 4th- 33mph
4th to 5th- 45mph

How accurate do most of you fellow efficient drivers find this to be? I must say that I find shifting very smooth at these speeds and their corresponding rpms, even for "cruise" conditions. The acceleration end to me seems to be winding out 2nd a bit too far.

I tend to skip gears when I can, most often skipping 2nd to 4th or 3rd to 5th. Will that get me a bit better mpg or would running straight through the gears as instructed be best?
