Hmmm, even if we use the most stringent definitions of a synthetic, such as primarily Group IV and V, we have more than just 0w-30. GC happens to fit that definition and is that grade. There is also Mobil 1 0w-40. There is Delvac 1 ESP 5w-40. The other grades of Amsoil fit the definition. So does Royal Purple. There are all kinds of exotic boutique oils, at varying prices and grades, that would fit that definition as well.
I know there are literally dozens of other oils that I've missed that would fit the Group IV/V definition. Let's not forget that things like PP, PU, Syntec, Edge, Valvoline synthetic, and others that fit the Group III/III+ are all excellent oils.
Yes, dparm, Jesus, not this again. My suppliers tell me all kinds of whoppers, too. Only Syntec is real synthetic. Anything except Syntec is real synthetic. Only RP is real. Only Amsoil is real. Only Mobil 1 is real.
In my rounds today, I met a lady running a new local oil supplier. Not only does she know more about oil than 95% of the parts people I've met, she also offers better prices than Walmart! Perhaps bassadict69's local brake technician can get an oil education from my local lady. She knew all about VW/Audi, Benz, BMW, and Volvo specs. She can get me Mobil 1 0w-40 in Canada for
$4 per litre. Yes, I had a stroke.
