Mobil 1, other synths on sale at Walmart

[Eggman]

They are both made by Warren.

I see.

Warren makes custom blends for various private labels. I wouldn't expect the formula to be equal from Amazon Synthetic to SuperTech Synthetic, though I suppose it is possible. I thought that maybe you had some test results proving that they are the same.

Both good products that exceed Mitsubishi specifications, right? So no worries with either.
