Good point... Your referring to availability & that is another thing to consider. My statement is more along the lines of cost so "Cheap Oil" rather than "conventional vs synthetic". But to your point conventional oil has been around for a long time but it appears its days are number as you show.@Artem @fantastic
I haven't seen conventional oil on the shelves at WM in years. The cheapest oils there are Supertech and Quaker State. Typically around $19 for a 5qt jug. And typically full synthetic or synthetic blend. So why go out of your way to find conventional that may only be 20 cents per qt cheaper when you can just buy a cheap full synthetic for a short flush? I guess I just don't get how conventional even enters this conversation.
