Perhaps someone can explain what the numbers mean.
Who “us”? Is there more than one...
Not much, because 5W cold start performance is not required in a hot climate.
In fact, multi grade engine oils are not required or necessary in the summer months. I would and have used mono grades in the past in similar applications, or just gone with 15W-40 because it’s cheap and available...
0W-40 FS would be my pick. No seasonal changes, no thinking.
Besides, I have 6 jugs if it for the same reason for use in a F350 6.2L gasoline engine that lives near the Yukon border.
I tried a pcmo 10w40 in my 2011 6.6L LML, followed by a UOA.
The result? Nothing out of the ordinary, except the oil sheared out of grade as expected.
The same engine now deleted for the last 80,000 miles with a Bully Dog tuner and Banks this and that, has a 50/50 mix of 10W-30 and 20W-50...
