I've towed my Jeep and trailer across the country with 5W20 dino and my Ford did fine. That includes pulling over the Rockies.
My $.02.
I agree with particular emphasis on the fact that this is "an economy car will 100HP".
But hey, if he wants to mess around with engine oil (that's why he's a BITOG member) and optimize his viscosity choice for the way he drives, "lots of city driving and short trips", then more power to him.
So yes he would benefit from the ultra light on start-up Toyota 0W-20 as would most economy car owners. The oil's not expensive and is a more efficient engine lube than a 5W-20 dino.
That said, I think it's about the only oil where he may even notice the difference.
