Less than past but still majority Synthetic base stocks.
I am no big PAO fan - its just a cost analysis.
Majority Group III alkane synthetics should be priced in the 5e/litre range not 10e/litre
Traditionally highest performing Synthetics have AWAYS been group iv + v blends.
Now its changed if there is money to be made for big oil.
I ask they pass a good chunk of these savings on to the consumer.
Any make pamphlets available at point-of-sale describing what the new synthetics are and how the definition has change and why.
First of all, that PDS is 3 years old. Maybe I was looking at 5W30 that I am using in Toyota. But who cares?
FINAL product is what matters. Again, Mobil1 ESP Formula 5W30 was majority Group III, yet had better performance than all Gr IV or V oils.
You are making assumptions how much it should cost and how it should perform. Motul when it was PAO was perfect example of average oil.
Considering that you think that cost is absolute driver of what Mobil1 (or any other company) is going to offer, and that PAO "traditionally" is better performer, Mobil1 0W20 EP would be relabeled as VW508/509, but it is not. Mobil1 5W30 EP has hefty amount of PAO, new Mobil1 5W30 ESP does not, yet ESP is superior oil in every aspect.
