IMO, they want to keep consumers in the dark. I went back and looked at the Pennzoil response to questions and my memory was correct. Pennzoil states in a straight forward fashion that PU is a blend of grp III basestocks. I really wish that XOM would do the same thing with their products.
Teddyboy,
I agree with you on this, but it is just the way it is. For 30 years I didn't know about base stock groups. Ignorance is bliss. All I knew was the performance was very good. Two years ago I called and ask Mobil tech what group Mobil 1 oils were, and the tech said " we consider all Mobil 1 oils to be grp 4". Well since then I have learned that Mobil 1 base stocks were a mixture of up to 15 differant compounds.(that may not be the right word)So I guess XM makes their own base stocks to their desire that has proven to be fine, so telling the public what would be their grp is for Mobil 1 oils would be futile(very few would understand) and confidential.
But then you have Shell when you contact them will tell you what basestocks their products uses then you have ask what is up with EOM? Why are you trying to keep it a secret it just makes you want to ask more questions.
Well, I guess they might be ashamed of the poor quality of their base stock, or you wouldn't understand it if they told you, or their basestock is somewhat differant than others and they keep it close to the vest. Hush Hush you know. Also no oil company tells the public everything about their formulation. They only tell you enough to make you think "I got the scoup".
