I have a 2008 Silverado 5.3 with 163,000 miles that is using some oil. I have had AFM turned off with my tune since at least 70,000 miles but still using some oil. Is there an issue with moving up to a 10W-30 since my truck technically calls for a 5W-30?
Since I live in middle TN, it gets pretty hot here in the spring/summer. I was looking at the PDS between the 5w and 10w Castrol Edge and from my untrained eye, they seem pretty close in thickness? At least when it comes to cSt 40/100 numbers. Where it's not identical is the CCS (-30 for 5W and -25 for 10W). I like the 10W with the 6.6 NOACK vs the 10 with the 5W. Is there a "thinner" 10W-30 out there that might be better or closer to a 5W-30?
I want to make sure the 10W still pumps and flows as easily as the 5W to prevent cold-start noise but want something with a lower NOACK.
I'm due for an oil change soon and considering giving the Havoline ProDS a try. The numbers look pretty similar between the 5W/10Ws but their sheets done mention anything about NOACK. Their cSt numbers look very close but it's the CCS V numbers that are off due to the different test temps.
