I had to stop by WalMart today to see if they had any "Tennessee Beauty" strawberry plants - they are getting difficult to find. Any way, I found a path to the plant section that involved passing by the oil. I wanted to confirm that TropArtic and TropArtic synthetic blend were the same price. They were, $1.48. To my amazement there was NO 5W20 Havoline, Pennzoil, SuperTech, QuakerState, or Mobil 1. Except for Mobil 1, there wasn't even an empty space on the shelf. The only 5W20 that I could find was PP and Valvoline. There was a lady restocking the Havoline and I asked her about the lack of 5W20 and if they were going to stop carrying it. She said "I don't know, but I just replaced the shelf lable with 10W30." I looked around and the 5W30 was missing for Havoline, SuperTech, and Pennzoil. Do I live in an area where 5Wxx just doesn't sell in the summer? I thought that 5W30 had been accepted.
