Not to derail, but a 5w-30 is far from pointless. Considering I commonly run conventionals, including in the F-150, are you willing to pay the premium for my jump to 0w-30? You might be interested to hear that at least in this neck of the woods, one of the bigger retailers of oil, Canadian Tire, has gotten rid of almost every 10w-30 synthetic on the shelf. They seem to agree that 10w-30 synthetics are obsolete, particularly since nothing currently specifies such a creation. Various 5w-30 examples meet some of the most modern and demanding specifications out there, from basic SN/GF-5; to dexos1; to dexos2; to current A3/B3 A3/B4; A5/B5; and E6, E7, E9.
