I just picked up a case of Napa Brand 5w30 Full synthetic for $2.95 per qt. I am running this in my 04 Hemi Durango with about 5K miles. Does anyone know anything about this product? I have been to two different Napa stores and both told me that it is made by Valvoline. It is brand new to Napa and this is the cheapest I have ever seen a full synthetic oil, I just hope it is Valvoline, it carrys all the right certifications on the label.
