Castrol GTX High Mileage Oil 5w20

[blackhondaccord]

Does Castrol GTX HM 5w20 oil have synthetic in it ?
recentley noticed the Mobil Super 2000 in 5W20 (which is a high mileage oil ) states that it has synthetic in it,
Castrol does not come out and state anthing on its product.

I think all 5W20's have a little synthetic in it but they don't advertise it.

MaxLife 5W20 has group III "Synthethic" in it. Still has 170 ppm moly and MaxLife seal condition. I would use it when my K24 Accord get to 100k miles

It says part synthetic right on the front label.
