So I've been running the oil for about 1.5 k miles now after switching from M1 10W-30/15W-50 mix in my LT1 and just wanted to let everyone know how the engine seems to be running with it, these are my personal experiences with it, a UOA is coming at 2k....
- The engine is quieter at startup, but slightly noisier when the engine is warmed up
- The oil pressure is higher at idle, but about the same at higher rpms
- The one thing I just noticed today that makes me very happy is that my engine would make a "cracking" bearing like sound on hot starts, but since I've switched to this oil I have not heard this noise even once
- The oil appears only slightly darker than it was 1k miles ago.
- It takes this oil a little more time to drain down to the oil pan.... i noticed i have to wait a couple more mins before i get an accurate oil level reading
- There has been NO consumption at all so far.
At first I wasnt very happy about the oil because my car seems a bit louder during operating temperature, but then when i noticed the "cracking" start-up sound went away, it made me happy since this is the first oil that has accomplished this. It may be that this oil is a bit thicker having 14.9@100, which would also contribute to the higher pressure at idle. I will be sending a sample to blackstone when the oil hits 2k and will be switching to GC to check out the hype
I wish that GC was slightly thicker, like a 13.5@100, that would be perfect for me since Im afraid that the thinner 12.1@100 will make the startup noise return
