My husband who is the vehicle expert in the household, see his website HERE, mentioned to me that Castrol Edge is currently running a rebate, save up to $15. Click HERE to see the rebate form. I haven’t found any good deals but did read that some Walmarts have this oil on discount. We’ve found in our experience that Walmart and Sam’s Club is the best price for oil. On occation we can find some good deals at Advance Auto.
Let me know if you find Castrol Edge on sale!
