Not that I know of, I have tried to see if anyone would put that on the bottle, but so far haven't found it. I assume they don't because they want to have people believe that it is "synthetic" even if it may not be. I will look on some bottles when I get home to see for sure.

In fact the new standard of oil will come out is GF-4, the current stuff (they have this on the bottle of Mobile 1) is rated GF-3.

Here is more of the saved info I have:

"Performnace of a motor oil is rated by the API (American Petroleum Institute), and uses a two letter rating system (as opposed to the numbers used by the SAE) for gasoline motors, and another two letter system for diesel motors.
For gas motors, the first of the two letters is always an 'S', which stands for 'service station'. At the time the system was concieved, (1961)it was thought that most drivers of gas-powered vehicles would get thier motor oil from the local 'service station'.
The second letter denotes the particular additive package in the oil, and started with the letter 'A' (naturally).
So, in 1961, the first additized motor oil availible was rated as 'SA'. (detergents/dispersants were the first additives put into american passenger car motor oil). As the performance of the oil was increased thru the use of more and improved additives, the next letter in the alphabet was chosen. It went next to 'SB", and then 'SC', and so on and so on. Today's motor oils are all rated as 'SL', to be supplemented in 3 months by a totally new category of oils rated as 'GF-4'(a whole 'nother story!)
This system is considered to be a superseding system, so any newer, higher rated oil can be used in any older vehicle. You will derive extra benifits from the use of modern oils in older cars, especially fuel economy.
Whenever a new rating is introduced, the previous rating is discontinued, so you will never see any 'old', lower rated oil in the stores or shops anywhere, unless someone has some VERY old stock. Extremely unlikely, so don't even worry about it.

The two-letter diesel rating is much the same, but begins with the letter 'C', which originally stood for 'commercial', because it was then thought that any diesel powered vehicle would be a commercial, not passenger vehicle.
Diesel ratings started at 'CA', and are today at a rating of 'CF'."
