Is there a good site where I can learn the meaning of all these E6,E7 CK-4/SN designations. They start to make my head spin after a while. Why is Phosphorous valuable etc.
Many thanks.

Builder approvals usually cost money to get the certification.
Some boutique oils and oils from small blenders aren't actually certified due to the costs involved. It's not economically practical to get the approval so they use words like "complies" or "meets", however no formal approval actually exists.
The approval is required for warranty coverage if you have an oil related failure. Some oils, which do not have any formal approvals, could actually be superior to the one you are "supposed" to use. This is the heart of the controversy.
Phosphourus is a very effective anti wear additive. It exists in 99.9% of all engine oils in the form of ZDDP (Zinc dialkyldithiophosphates), usually combined with Molybdenum or Antimony for a synergistic effect. Some HDEOs have more P than others. It is proven and has been around for years, except it can poison a catalytic converter before the warranty expires if your engine has an oil consumption problem. As a result, the levels of P are being reduced in all oils over the last 15 years. I prefer > 1000 PPM of P, E6 lubes are limited to < 800 PPM.
CJ-4 and CK-4 are API diesel oil categories: https://www.api.org/products-and-service...el-c-categories
ACEA E7, E9 and E6 are European oil specifications: https://www.lubrizol.com/Lubricant-and-Fuel-Additives/Engine-Oil-Additives/ACEA/Sequences/ACEA-E6-16
