toyota synthetic oil

[menezes]

can anyone tell me who makes their oil, on the bottle it says "toyota synthetic oil" is it a full synthetic or a semisyn?

I believe it is made in the US by Exxon-Mobil to Toyota spec's,
And it is not the same as Mobil 1.
Toyota oil 0W-20 has about 900 ppm zinc and 700+ ppm moly--a pretty stout add pack. There are at least a couple fairly recent VOAs (one of them mine and one from BruceT or rcy I think) on this site. One from Canada bought and one from US bought.
