I buy my synthetic oil at Walmart - house brand.
Same here. We have the V10 RV (5W-20) a V6 Ford minivan (10W-30), a Corolla and a Frontier 4-Cyl (5W-30). I've been getting the Walmart SuperTech 5W-30 Full Synthetic, and everything's getting switched over. All those and the B&S mower are done. Onan Genny and Honda pressure washer are next. So far so good.
Our boat with a V8 Chevy badged MerCruiser, calls for a 25W-40 "Blend." I can see Synthetic Fans, and Dino Fans, but what makes "Blend" better than Pure Either, eludes me. Walmart has MerC's Quicksilver branded of that oil, so at least for now... I'm watching the guys who are using Mobil-1 15W-50. So far that seems closest to 25W-40.
Oil's bad enough to pick. Gear Lube's terrible. Then there's Filters, but if you're looking for More Fun...Antifreeze Coolant!!!
