Hi Everyone
I own a 1995 Nissan Hardbody V6 4x4 with 71,000 miles on it, and a 1998 QX4 4X4 V6 with 50,000 miles on it. I change the oil and filter in both every 3 months or 3000 miles (WCF- Usually months before miles)using Castrol GTX 5w30 winter time- 10w30 warm weather and Nissan oil filters. I have been thinking about other brands of dino oil ie:Chevron, Motorcraft, Pennzoil,or Shell something I can buy at a Wallmart or autoparts store.Are any of the other oils a better choice than Castrol GTX for overall protection/ performance/quality?
Thanks in advance
