Just switched from SuperTech 10W30 to ST 5W30 for the winter. The new oil is very clear, almost like Pennzoil. I know that with the Shell merger that the Shreveport blending plant that was handling SuperTech will be closed. I sort of assumed that Shell would have extra Equilon capacity from the transfer of Havoline to Chevron and that (maybe) those plants would produce the oil for Wal-Mart. I don't know much about Shell's oils. Always heard they varied greatly in different parts of the country. IMHO Pennzoil is the best of the Pennzoil/QS/Shell lot so if be some chance this is Pennzoil so much the better. If it's simply the same old Specialty Petroleum stuff and 5W30's a different color, that's OK I guess, but I really prefer slightly darker colors since they're easier to read on a dip stick. Come to think of it, they probably haven't had time to close down any plants and get product through the distribution channels so this is probably just a variation by weight-- or maybe it's that part of production that Warren Petroleum took over. Johnny??? Anyone???
