I keep meaning to contact Motorcraft and see if I can find out what the deal is on the 5-20 being labled a blend but the 5-30 not, even though they are both described on the back as being made from "synthetic/hydrocracked base stocks". However I keep putting it off because I dread the getting the usual customer service runaround.
So I though it would be worth checking before I do, to see if anyone else has done it for me.
