Just had a question for you folks. When is it ok to change out the old dino oil and replace it with synthetic? I just changed our oil at about 10,000 miles, second change, and wonder if I should loo...
It might not give more life but it can be done when you are ready. I lean to synthetic but have not read proof or even near proof it was functionally better in the real world in real time. Some say even new dino has a lot of synthetic in it to pass newer specs. I know there is not a huge price difference in cost per mile today and one reason I lean towards synthetic just in case it helps. :)
