Its just as modern and better then any other oil, its an SN heavy weight multigrade oil with a robust additive package to boot.
Doesnt get much better people!
Someone above posted a recent UOA and here is Castol's own propaganda.
Mostly only in the USA are such 5 and 0/20 "lite" oils used because of retarded EPA mileage demands, not all the world works the same as us. Heck, I can by 20w50 HDEO oils overseas, here in the USA I have to search every corner of the internet for them. Now dont misstate my post, yes 20/50 is rarely called for in new automobiles, but there are some overseas but forget all that, its an option we ahve and great for bikes or other types of applications.
Click here and see the UOA a few posts above mine.
Castrol GTX dino is certainly not outdated, but i would not use it because of its low Zddp in an older car which potentially has flat tappets.
What you said that 20w50 is rarely called for in new cars, i don't know of any European, American or Japanese manufacturer that wants 20W-50 in 2018, 20w50 in 2018 is exlusively reserved for older cars.
Chevy wants M1 15W-50 for their Z06 corvettes at Tracks.
Ford wants people to use full-syn 5W-50 in their Focus Rs and the more wild Mustangs.
