No. Forget about mpg: difference is miserable.

Syn blend is OK. Pure synthetic are what I would avoid, except, may be, Mobil1 0W40 and Shell Rotella 5W40.

Good choice, IMO.
One more question: are you a fanatic believer? If not, put a quart of ATF for 400-500 miles trip and change the oil. If you was Europenian, I would advise you to drain oil-AFT mixture, prepare a 66%/34% of oil/diesel fuel mix and pour it into the sump. Then idle for 15 minutes, drain this cocktail and add new HDEO oil.
Ignore this whole post. Obviously this guy has never heard of a 0w-30 hdeo or 0w-40 hdeo which in my opinion would be ideal in that you get the detergency of an hdeo with the instant pumpability of a 0w.
Devlac makes both a 0w30 and 0w-40 and I've seen pails at Napa of different branded hdeo 0w-40s and I'm pretty sure rotella now has a t-6 0w-40,so you do have lots of options as far as hdeo's in a thinner start up grade.
M1 0w-40 is cheap and could be your perfect choice based on availability,cost and admirable performance.
