Latest UOA with the infamous "unicorn blood": Redline 5W30.
My car seems to like it...
Yes, I know the mileage info doesn't add up -- techically this was just under a 4K OCI and I rounded up (also, I recorded lower than actual overall miles by a bit accidentally -- OCI was
actually about 3850ish. Close enough.)...
Anyway, wear numbers are lower, suggesting that Redline does as well or better than the German Castrol at 4K.
I'm probably going to let this fill-up remain until about 5.5 - 6K and see what wear materials are like. If they remain low, then I'd say Redline wins both overall, and especially because it will outperform on a longer OCI. If wear materials go up, then I'll compare to the Castrol at similar miles from previous oil change, pick the one with the lowest values, and stick to a 3.7-4.5 OCI.
