Asking cause I have about 6 cases of 5w30 sitting here. Going to use it in my cars but worried of going from Castrol GTX HM.
If it will do as good or better then it's on. I will start useing it untill it's all gone then maybe stick to it.
My dad has praised pennzoil for years but I like Castrol. I like the bottle's, the smell and really seems to keep the engine clean.
BTW: I got the cases for $50.
I don't want to hear the sludge horry stories from the 70's, if it is something lately then I will listen up.
