Best NON-syn OIL
My car has only been run on non-synthetic oil for 130000 miles. Yes, suprisingly it is still running Ive heard baadddd things about switching. So I wanna know which is the best non- synthetic oil for my 7. Now I use Castrol GTX 10w-30. However I hear Halvoline is the best because of its base. Can someone clear this up ASAP thank you. Nate
