5w30 or 5w20

I have tried 0w20 and 5w20 early in the life of my escape when it had 30k on it. I change each out at 1000 miles due to the engine being much louder when warm, sounded fine cold. When i towed with it i ran 5w40 rotella and 0w30 m1 in the winter. I am going to run the 0w30 all year now. The 0w30 has been the quietest smoothest oil i've run in it. I've run the 30 and 40 wt oils for the last 100k in it and it runs great. Btw i had no difference in fuel mileage with any of the oils.

Yes the pacific northwest is ideal climate for running all kinds of viscosities. You can safely run really anything unless theres a bad winter over here. Which isnt too often. I can recall 2 weeks that were below 30F.

It might only mean a difference of 1/2 MPG, but multiply that by millions of vehicles and we can reduce dependence. I will say a neighbor of mine blew up his engine on a Silverado with only 30,000 miles on it. He was pulling a 8500 pound trailer for about 3000 miles but the weather was in the mid 50's, so I doubt it was the oil. As a die hard Chevy fan he contends it was the oil. He was within the OCI


Odds are if it was a Chevy it called for 5W30 oil, which is probably what he was running. I'd bet it was a mechanical failure and as you mentioned most likely had nothing to do with the oil.

OP- The 5W20 5W30 debate has been beaten to death over and over. If the engine is doing fine on a 20 grade oil stick with it. If or when the engine starts using oil which may never happen, then try a 30 grade oil. Honda tested their engines as did Ford, and they are confident in using 20 grade oils IN APPLICATIONS THAT 20 GRADE OIL IS SPECIFIED FOR.
 
I will let everyone know when all the vehicles in Miami-Dade County drop dead on the side of the road using 5w20 where the temperatures are in the 90's at least 9 months a year and traffic is gridlocked daily.

Whats funny is the same engineers spec'd different oil for the same engines outside the usa!

Look up a vehicle and see.


Reason being in many parts of the world the oil we have available in the USA is not available in those places, or extremely hard to get. It's been discussed here already.

Because its not in demand because its not required.
 
Because it is not in supply or very limited supply they offer what is available.

Is it harder to ship 5w20 than it is 5w30 or 10w30? I fail to understand this reason. Its not in supply because its just not in demand, that makes more sense.
 
^^

Good decision, if it ain't broke don't fix it! Stick with what has been working for you!
 
I love Oil Debates.

I used to live in Carrolltown, with was North of Ebensburg, which was North of Johnstiown. I used to drive Coal truck(Triaxle) and hauled alot of coal thru Punxty. I forget how massive the hills are whenb i go back. Ive been in Florida for about 9 years and my wife will never go back, she says. It is Beautiful down here just about all year.
 
Hey panzerman, and I hear you on the warmth of FL. I was in Panama City in 05' and nice area/state. I was to Cape Caneveral when I was young to see the space shuttle and other stuff. Yeah its hilly and mountainous up there.


take care and have a great weekend.
