So for my 98 Mustang 3.8 with 79000 miles, I am thinking of using one of the super tech oils. But I can't decide if I should use the conventional or the full synthetic. I only drive it in the summer to shows and cruises etc, so only gets less than 2000 miles per year, but generally change once a year. I will probably use the high mileage version just because of the 22 year old seals and gaskets, and there is some minor seepage. Owners manual calls for 10w30, and even though ford later said to use 5w20, I am gonna stay with the 10w30.
BUT, conventional or full synthetic? Wish they had a semi synthetic.
