2001 screw 72540 miles what oil 5w20 or5w30? thanks for any info.

 

u can use either but 5w30 is cheaper

 

With the mileage on the vehicle and the summer coming soon, go with the oil that has the higher viscosity for better protection. When the oil heats up it gets thinner but if it gets too thin, you're in some serious sh#t.

 

Either will work fine...

 

I'd use Havoline 5w-20 you won't be disappointed. I just switched from Motorcraft 5w-30 and got tired of the poor mileage, and unresponseiveness of it. I ran Mobil 1 5w-30 before and Havoline runs just as good as it did if not better. Really any 5w-20 is good all UOA's are coming out just a good as 5w-30. Good luck. Eric

 

The 5W is the important part. 20 or 30 depends on the weather you're going to encounter over the next few months. The 5W is important because the newer engines have much tighter tolerances and need the thin weights to flow through all of the oil ports, especially on start-up.

 

Just don't use 5w20, only reason ford changed it to that is cause it get's maybe .5-1mpg better. It is thinner.
