Discovered Mobil 1 does make a 5W50 synthetic oil.
My wife found a wholesaler online (I'll post the link later), where we were able to order two cases. Frustrantingly, our cars supposedly use not 6, but 6.5 quarts, so I need to buy another quart to make that 2 oil change intervals. While I'm on that subject, my manual says there's a 7500 mi interval for the oil change.... does anyone actually follow that or do y'all change the oil at 3k or 5k?
BTW, the only other 5W50 I've found is Castrol GTX, other than Motorcraft.....and I have no idea who manufactures that oil.
