Hello all, Long time lurker... First time poster.
Surprised this hasn't already been done... But I think it would be a good idea if someone could make a document/spreadsheet, listing all the major synthetics (could also be done for conventional oil) in one column, and all the major specs in other columns, with a checkmark if it is approved or not. Documentation of the spec on the company's website and/or actual bottle would be the requirement for the oil to receive the checkmark. I guess it could get complicated with all the grades... but I think it still could be done.
I think it would be good information, and would help a lot of people in deciding. I, after some research, now only use synthetic, but price IS still a consideration, along with meeting company specifications (for warranty purposes).
Just a thought...
