Hmmm SuperSyn to cover-up deficiencies of Tri-Syn...anyways, I just thought SuperSyn was a U.S. moniker because Mobil's overseas lineup was supposedly "better" than ours...we don't even have 5-50.. Did you guys ever have Tri-Synthetic???
Wow you think you're lucky to get it! It still looks as if M1 SS will take a couple more years before it comes out here in Australia! I am currently using M1 SL Tri-Synth, which apparently is similar to the SuperSyn aynway. So i'll just have to make do with that!!
