I use the oil my local car garage (independent) gets in 40 gallon barrels - he has 10-40 and 20-50, semi synthetic - he charges me £5 for a fill up and I do the change myself - so he doesn't really know howmuch I am pouring in - but he says it more than covers it. Bikes have done plenty miles without any adverse engine wear - I reckon 187,000 miles without anthing on the engine other than one exhaust valve guide isn' too bad.......so I would say this oil is high enough grade - it is rated for modern turbo engines, even high performanc eones.
