If TGMO 0w20 doesn't give you a fuel economy boost the AFE surely won't. It might be a couple bucks more than AFE, but if it saves you gas you might come out ahead.
Yes, it is much lighter and is an OEM lubricant that doesn't carry any recommendations for Ford or GM applications, unlike the Mobil products (AFE and EP) which BOTH carry recommendations for Ford and GM applications that spec 5w-20 and 0w-20:

Mobil 1 0W-20 Advanced Fuel Economy is recommended by ExxonMobil for SAE 5W-20 and 0W-20 applications in all types of gasoline fueled passenger cars, SUV’s, vans, and light trucks.

And neither oil is likely to yield a perceptible increase in fuel economy over a conventional 5w-20, certainly not enough of one to pay for the difference in price between something like PYB and TGMO/AFE/EP.
The only way the more expensive oil would pay for itself would be through extended drains. Or if the OP lived in Edmonton, Alaska or the Yukon and could actually benefit from the better cold flow characteristics of the AFE/EP products.
It's great Mobil says 0w-20 AFE meets/exceeds Ford WSS-M2C947-A, but if your Ford specs 5W-20, the relevant standard is WSS-M2C945-A. While Mobil offers a generic statement that its 0W-20 is appropriate for 5W-20 applications, they don't say it meets the ...945-A standard. Wouldn't take much space on the PDS to do so, leaving some of us under warranty to wonder if it's a risk.
