I just happened by the auto parts store today and seen a sale on Casterol Edge 5w50 for ~$35 , 5 qrts and a Bosch filter. They didn't have the filter so they gave me a Motorcraft instead. So I bought 10 qrts and 2 filters for $69.94, that come's out to $5 and some change for a quart. The owner said they are going to have the same deal next month only it will be Mobile1. I'm not sure how wide of an area this sale covers but it's there for anyone in South Central PA. I might need to take another trip up there, it not like it will go bad before I use it.
