If you can wait a couple days you can get Mercon SP from ryderfleetproducts.com for $5.98 a qt but the minimum is 12. I just bought from them last week and had it in 3 days. Total cost with shipping $88.98 and that included the front external filter.

 

Thats where i buy all mine from,fast no problems,cheap,instock, ryderfleet.

 

That’s a good price, beating FiltersOnline.

 

Looks like they updated the bottles. I noticed it on a shipment of the PSD anti gel and cetane boost I got last summer as well.
I think that is the same bottle the "new" Motorcraft oil comes in.
