The testing being done, is correct.
However, to make the test 100% valid, instead of 99%, they will have to pay millions for the testing.
They can't afford it, because some big oil companies will come after them(castrol, Shell ++).
Note that the two oils who got the best results, are quite small, niche products(RP and Penrite).
This is a good demo on what the socalled "synthetic" Castrol is good for. Only a hydrocracked dino oil. Good for tractors, though.
Not a matter of stepping on toes. Someone needs to post the StreetCommodores retraction of that article, which was driven by individual input not the evil "big oil companies".....
