It is overwhelming and confusing to see the product comparison especially with upcoming SN Plus certification.
So it seems PUP is no longer the best for turbocharged engine due to LSPI issue.I am wondering if for non turbocharged engine, whether A5-12 cert on PUP kinda proof that the oil is better than standard PP GF-5 SN-RC.
The other interesting part is PP 5w-20 has better pour point and viscosity at -30C compared to PP 0w-20, so what should be deduced ?
Just wonder if there is other durability property to be considered between PP and PUP ?
Thank you
