I have been to 3 Wal-Marts, 2 KMarts, Home Depot, 1 AAP and 1 NAPA in the Northwest Indiana area, between Valparaiso and Merrilville. Absoutely NO ONE has more than 2 quarts of 5W30 Castrol Syntec and absoutely ZERO 5 Quart jugs in either Castrol High Milage, Castrol Startup, Castrol Synth Blend, or Castrol Syntec. I hit up AutoZone but they only had 1 quart bottles and I would rather get the 5 Quart jug since you basically get 1 Quart extra for the same price and I like to have a little extra sitting around anyway. I am just curious if anyone else has seen Castrol products missing en mass from the shelves of their favorite *-Mart? I have been using Mobil 1 5W30 and been perfectly happy with it. Just want to try the Castrol Syntec in my Infiniti G20 to see how it runs since I have had such luck with Castrol High Mileage in my girlfriends MX3 and in my old Mazda Millenia. I know I know, it may sound stupid since I have read that Castrol Syntec is not really a favorite around here. Thanks in advance.
