According to Mazda:
In starting and operating temperatures below 20F, use 5W30
In starting and operating temperatures between 0F and 80F, use 10W30.
In starting and operating temperatures above 30F, use 20W50
Conventional oils 10W40 and 10W50 have been shown to increase deposits in many high reving motors and are generally no longer recommended.

Former Moderator. RIP Icemark.
There are a couple of people that still use 10W40 and 10W50 claiming that the new formulations and quality checks are better for reduced additives (mostly long chain polymers) that can burn and leave ash and sludge, but I am not convinced.
10W30 in the winter, 20W50 in the summer.
10W30 in the winter, 20W50 in the summer.

Nevermind. I was asking about deposits with 20W-50, I misread that it was an issue with 10W-50.
I run 20W-50 in the summer, 10W-30 in the winter. I think it's time to switch over to my winter oil.

Yeah, I rarely see 30F at night. I'm in Fresno, California and thats in the central valley. I think I saw 40 once. I've seen 110 in the summer, and this summer had high 90s and 100s throughout. I never actually tried 20w50 before, but I am going to when my Turbo II starts running. My old 91 NA took 10w50. We are still getting mid to high 80s here btw. At least its not humid like the summer. lol. Nights are like high-50s to mid 60s.
