engine oil
Im gonna be installing headers either end of this month of next month, and i did some researching that you might have to take out the filter and drain plug for that extra clearance.
i have the syn oil already, but am not sure if that regular no name oil will be hurting my ls1.
im just not sure if it is ok to go from synthetic to regular.
