OK, I get to toot my horn once again
I use 20W-50 in EVERY vehicle once it reaches 100,000 miles, until then I use 10W-40. I live in the Northeast, and I don't "adjust" for temperature. I never get any "cold-start" ticking ever, even in the winter. ALL of my vehicles and engines go WELL over 200,000 with no problems or maintenance, short of changing oil, etc. And, doing mostly highway miles, I wait till 7500 miles. 3000 miles is BS unless you drive like grandma, it is simply un-necessary and costly. Most manuals will even tell you 7500. And I don't believe in synthetics. Why would I ever pay 4 times as much for that when I always go well over 200,000 miles using regular oil?
OK, that said, yes, if you have a noise and want to quiet it, try 20W-50. You may need to address the problem mechanically, but it will help to use thicker oil for now. Hell, you can even use straight 30W oil. And, yes, you can leave it in year-round. As I said, I live where we have weather changes, LOL, and never adjust for temperature.
So, that's my story and I'm sticking to it.
