but.....but.....but Great Value Supreme coffee has the same certs as that crafty, schmancy, fancy Columbian Supremo.
Harvest King really rocked here. All the fill station additive & base oil faucets were turned on high, when that empty jug made it's way down the conveyor belt line.
I think HK performed much better than most would expect from an oil that usually sells for $2-3/quart. To me, just proof that marketing works.
If you were told you had a cup of Columbian Supremo but in fact had a cup of Great Value Supreme, would you taste the difference? Perhaps, but I'd wager that at least 90% of people wouldn't know the difference.
Same principle here. I have no doubt that in some applications, some specialty oil has clear advantages. But in most cars on the road today? No advantage at all, except perhaps making the uninformed owner feel a little better.
