8.53 after rebate - local only - cannot buy online - Shell Rotella T6 5W-40 Diesel Engine Oil 1 Gallon at Walmart. Thumb Score: +18. 8.53 or so after rebate for a gallon, a steal for this synthetic oil, I use it in my motorcycles and rotary engines. Looks to be limit 2 with 2 separate receipts, rebate valid for in-store online. Rebate says not valid for Walmart.com purchases.
