ENEOS is the house brand of Nippon Oil.
I've run the Nippon Oil made Toyota Brand 0W-20 which is much the same product as the ENEOS 0W-20; namely GP III based, boat load of moly, same viscosity spec's and a 200 VI, but for half the price.
It's one of the lightest 20wt oils you can buy and I liked it a lot.
