I just noticed my Walmart has the Mobil 1 Truck & SUV 5W40 in 5qt jugs for $20.xx. Nice. I used to buy the Shell Rotella T "syn" 5W40 for $14.xx for a 4qt jug and an extra qt for $3.xx to top it off. Now I can get a bonafide full synthetic for just a few bucks more. It really pays to not have my wife at the store with me so I can actually look at the oil rather than just reach out and snag what I came for.
