Castrol banned from GM
Castrol GTX has been removed from GM's list of approved oils. The move comes after a recent test program conducted by GM to check several of their currently approved oils for compliance with the GM6094M. Look elsewhere for now if you're doing your oil changes with Castrol.

it is no surprise to me, from when I was a tech I found out Castrol does not have access to any refinery, thy buy everyone else's oils and mix them (sounds really healthy doesn't it)

Iv use it until now, with my next oil change im going to seafoam it and then switch to royal purple.
Its go to be better than quakerstate and penzoil.. those dam Pennsylvania oils have ash in them i dont care what you say, every motor ive tore down thats had it ran in it is more nasty than the tar pits.
