Why does my 7.3 rattle sound so different using LE oil

I'm coming up on an oil change very soon and am probably gonna be switching over as well. My brother switched over his last oil change. I texted him about cold starts with your 15w40 since it's been in the teens the last couple mornings, but he hasn't texted me back yet lol.

Well he finally texted back lol. He said cold starts are definitely better than other 15w40s but not the same as with the 5w40. He said he's thinking of going with the 5w40 for winter and 15w40 the rest of the year. He said it also used very little oil since his last oil change compared to the other oil he used before switching.

Yeah, there’s definitely a benefit to 5-40 in the cold. Its tough for me to recommend 5-40 unless i can actually hear the truck start cold before the change. I don’t want people paying too much for what they might not need. I feel like if i blanket recommend 5-40, im no better than mist other oil d bags. They do that to make their life easier

Oil d bags, lol.. definitely need to draw the line there haha!

Yeah, my cold starts are getting worse as the starter gets another year older. I've got to remember to do that crap when it's nice out.
