For my Jeep 4.0 (tractor engine) on sale at Napa for $13.69. The containers are different, but same part number and specs per label except the SP, so one is older. Like seeing the flag on the label. Hoping this gives me a good intro to HDEO for the 4.0, and maybe I'll switch to this from others of the same grade. I have Formula Shell in reserve and Havoline HM semi synthetic from the 6 qt box in it now.
