So to our oil industry guys, whats (beside price and marketing) is the difference in Molble 1 full, and Wally's full?
I'm not an oil industry guy, but I did stay at a Holiday Inn Express last night. Just a car nerd.
As of a few years ago, Mobil1 was still a true, manufactured-above-ground synthetic oil. Wally's is refined crude oil that is likely Quaker State or Pennzoil in their own bottle. Nearly every store-brand oil across the country is either Quaker State or Pennzoil.
Important to note... nearly all crude base oil stock in the US (lubricating oil without the additives to make it whatever it will become) comes from Quaker State... which is a sister company to Pennzoil.... which are both owned by Shell. At the QS refinery in Emlenton PA, you could see trucks from Valvoline, Castrol, Chevron, Mobil... all lined up to fill up with base stock. That refinery is now torn down, but I haven't been there since I was a kid. Not sure if they still use it for distribution or not. From there, each company adds their own additives to make their own formulations of 10w30, gear lube, 30w, etc. The "seven sisters" (the 7 biggest fossil fuel companies) all have their place. Companies like BP and ExxonMobil are primarily in the business of using the smallest and largest carbon chains; natural gas, gasoline, propane, then plastics. Shell is more in the middle with lubricating oils. From what I understand (I casually read the yearly publications they send me as a shareholder), many of the companies crack off what they want out of the crude and sell the rest to the other companies for what they want to use.
Important to note... Mobil's synthetic is still made above ground by Mobil or one of a few other manufacturers, but their non-synthetic is sourced from one of the two largest refineries in the US... QS or Pennzoil. That is to say - the difference between Mobil oil and Mobil1 oil. Different animals made in different places by different divisions of the ExxonMobil corp. Mobil1 came from the Mobil/Lukoil side, and as I understand it the regular Mobil non-synthetic oils are now produced by BP when BP acquired parts of the Mobil corp during Exxon and Mobil's merger in 99. Source for that is anecdotal from a friend of mine who works as an engineer for Bayer who does a lot of engineering work for ExxonMobil in Houston. So, in short, when you buy Wally World synthetic oil, what most likely happened was ExxonMobil or BP pumped it out of the ground, cracked off what they wanted, shipped it to Quaker State who further cracked off the mid-chains for lubricating oil, it was then shipped as base stock to Pennzoil where they filtered it, tested it, did some fine tuning with hydrogen cracking, added their secret sauce, then shipped it to a third-party bottling facility to put WalMart's label on it.
