I was reading a good article from one of the major additive suppliers. It highlighted some interesting industry trends and performance improvements. First, low viscosity and engine wear. It's no longer an obstacle and has been perfected. They are able to tweak low viscosity oils to have better anti-wear properties.
Another interesting topic the article talked about was the importance of a high quality viscosity modifier for extended drains. I was surprised to read that viscosity modifiers are not fully understood in the industry, especially over long drain intervals. In their testing, some oils lost their pumpability after only 8k miles, which is extremely important.
Tailored "salicylates" for PCMO's, especially in extended drains. Low SAP oils. Oils using salicylates outperformed sulphanates in deposit testing.
