Yeah, the Walmart brand is made and packaged by one the big boys perhaps QS or a few others.
It probably has a Group III oil base which is the same as Castrol and most others, but I can't be sure. Hey, we are driving Contours here, not Ferraris, so any Synthetic should be good enough!! Besides the Super tech meets Corvette and Viper specs, so it should be more than satisfatory.
Coincidentally, one of my local Walmart was selling the 5 quart synthetic jugs for ONLY $8!!! Yeah, $8! That's cheaper than mineral based oil. I bought a few, needless to say. One guy there was buying regular Valvoline for over $9 (about synthetics, he said "Oh no, I never mess with that stuff!").
On a side note, AMSOIL does not synthesize ANY of their oil components, they only buy the ingredients from others and blend everything in a big mixing tank!
