Hey there im getting ready to change my oil on my 86 GT and my question is im thinking of using the castrol syntec blend oil, i get it for the say price i get regualr oil(i know the girl at autozone). the car had 150,000 miles on it, the oil is changed every 2000 miles or 2months what evers first, I was wondering if it would be okay to use this oil, will i have leaking probably, i wasnt sure since its not a full syntec.
thanks alot
