Hey guys, I have a 2001 v6 3.8 liter (obviously) and as you can probably tell from the title, I need a oil change lol I normally do it myself but I just recently bought this car and Ive never had a car with high mileage before. Mainly I'm looking for suggestions on which Non-synthetic oil I should use. My friend had a 99 mustang with 98,000 miles and used Castrol GTX 5w30 high mileage and said it worked fine. By the way I have 110,000 miles (that number still scares the living day lights outa me lol). I was thinking of using the same stuff but I figured I'd ask here .
