oil weights
i hear alot of people say i use 10w30,10w40,or 100 weight you get my point. even though ford recomends 5w20. it has alot to do with fuel economy but also oil is much better these days than in the past. we all know that most wear happens at start up. the thinner oils get to engine parts faster and also drain back to the pan quicker very important. i also hear people that put in a high volume oil pump because this must be better. not unless the oil drain holes are opened up in the engine. you will just pump all the oil up to the valve covers and cook. it will take forever to drain back down. stock oil pumps are more than enough in 99% of the time. even in high performance engines.
just something to consider when your pondering these questions. have a good day

You make some good points. I believe the 5w20 is only to minimize CAFE fines. However, if they are dead set on customers using 5w20 they may be tailoring the engine to it. Maybe the oil pump design is best suited to 5w20 and a 10w30 won't pump as well. I don't know. If I ever get a Ford that specifies 5w20 I probably would run minimum 5w30 in it and am more inclined to try 10w30. But each year as running changes are made in the engines, these thicker oils may become more and more unsuitable for them. I'm glad I can run 10w40 in my '95 300 I6.

Hey guys and gals.
I checked one of the oil guys sites yesterday and they
recommend 5w30 for my truck and something else for
my wife's ASTRO Van V6. I had to step through boxes
at eace level make, model, year, engine and then they
gave the results.

and fill it with a good quality 10w30 year round. There is no need for 5w if you are above zero F. In fact, you are in AZ, right? You could go with a 15w40 year round (Penzoil has a 15w40, Long Life I think, that is readily available).You will likely consume less oil with a 10w30 than a 5w30 and that should mean less engine deposits.

Roland, Check these out:

CAFE is Corporate Average Fuel Economy. The latest by Ford is 5w20 oil and here is what the EPA told them they had to do to:
