Tom Glenn's column in November LNG
I did a search of their website and it looks like the development of this is still in progress. It's nice that the PQIA is stepping up to help with the policing of marketing claims for lubricants. They've already done fantastic work with viscosity grades and additive levels - based on the limited data available. So if blenders cooperate with this certification program it should do well for the industry. Hopefully it won't cost much to participate.
...the Petroleum Quality Institute of America will expand its motor oils certification program to include a "Certified Synthetic" mark. This mark will be based on an audit of the blender's records to verify the use of Group III and and API-licensed, base-oil-and-additive combination.
