The oil really isn't going to matter. Just try and pick something and run with it. I run Valvoline because that's what we have always used in all our farm trucks, personal vehicles, and because that's what Mark Martin used to have on the side of his car.But Valvoline does have a "300,000 mile engine guarantee" or something like that that might be worth checking on. I run the 5W-30 weight for the same reason Mustang5L5 mentioned, and I run the full synthetic just because that's the "accepted" thing to do with higher mileage Mustangs, even though it's probably not necessary.
The filter does matter; Motorcraft FL820-S is the only one you should ever run in your car.
+1. My dad is always picking on me about running full synthetic because his old E-150 work van has run conventional for almost 20 years now, and has nearly 600,000 miles on the stock motor. We have several farm trucks that have been beaten to death over the last 15-20 years with 250,000+ miles that have always had conventional oil.
I'll go one step further and say that the regularity you change your oil and filter is a whole helluva lot more important than what brand oil and filter you use....
i must be the only one. using 10w40 lol

You living in Dallas... I couldn't disagree...
While I was living in Vegas during the summers I would put in a 20w50 or something like that...
Well I swung by Walmart and they had the filter for $3.67 but no Motorcraft oil.
They had 5 quarts of Castrol GTX for 13.50, Valvoline for 15.50, and Mobil Super for $11.50. I don't have ramps and most jacks won't clear my subframes without jacking it up a couple inches with the factory scissor jack first...
For the price difference, I think it's easier to just take it to Ford and spend the $30. Looking at about $10 for labor.
There is absolutely no need for this and you're probably doing more harm than good. If you have a cooling system that functions properly 5W-30 is all you'll need.
You should all read this:
Introduction to Motor Oil
i've had over 20 vehicles in my lifetime... and on new OR low mileage cars. i would always use 5w30 and on older cars with higher mileage, like my current GT. i use 10w40 summer and 10w30 winter. never every hand internal engine issues,
For $30 you can bet the dealer is putting in conventional oil.
I use Mobil 1 with a K&N filter.
I'm sure they are, which is basically what I would put in it from Walmart anyway. I'm just paying $10 to avoid putting the car on jackstands, disposing of oil and cleaning up a mess.
I have never heard of a motor failing because someone used brand A as opposed to brand B, I will use synthetic when I find some on sale..other than that whats the point...because all that high priced oil these people on this forum buy is eventually coming right back out of the car.
