Hi All, Been reading the forums for years. Never had to become a member because I just searched and read what I needed. No need to add my comments to piles.. Until.. The dilemma I run into is I'm moving from Syn 5w-20 (Black) to Edge EP 5w-20 (Gold). My car takes 6 qts. We can easily buy the 5 qt jugs here, but not 1 qt (in 5w-20). No one carries it. AZ, AA, WM, etc.. I can buy another 5 qt jug (5w-20) for 27 bucks, or a 1 qt 5w-30 for 8 bucks. Which would you gents do? Mix the weights (which is no biggie), or buy another jug and store 4 more quarts around the house? I plan to do my next OCI around 10K mile on the Edge EP until I get a UOA at that time. Please Advise.
