I am preparing to change the oil in my new to me 2006 Land Rover LR3 v8. Manual states oil needs to be WSS-M2C913B compliant. The manual recommends Castrol GTX 5w-30. Is it safe to use a oil that is WSS-M2C929A approved? I have Castrol 0w-30, M1 5w-30, Valvoline 5w-30 Full Syn and PP 5w-30, all in the garage bought on sale! Is it also safe to assume that if GTX meets this requirements, that these full syn's should too?
Thanks!
Thanks!
