I don't see the Mobil Super Synthetic discussed on here very much. I suppose that is because it's mostly on sold at auto parts stores with the usual parts store high price. I use up all available M1 rebates already for another vehicle. The Pennzoil rebate isn't really worth it anymore with the recent price increase. QSUD and Magnatec are about $19-20 at Walmart stores or online so why bother with Pennzoil rebate. Today I noticed the somewhat rare Mobil Super Synthetic at Rural King for $19. It should be good enough for 5-7 k OCIs in our Honda CRV grocery go-getter short-tripper. Any Super Synthetic fans out there?
