I find the reading involving the many oil topics are very interesting posted on this board. I presently use Castrol GTX 5w30 /10w30 oil in my 1995 Nissan Hardbody Truck, and 1998 QX4. Both vehicles use Nissan oil filters and Castrol GTX oil every 3 months or 3000 miles. Is there a better dino oil I can use or stick with the quality of Castrol GTX?
Thanks
