There are many brands, but very little difference. In fact, one of the dirty little secrets about motor oil is that most brands are made by production fillers who put the same product in many different brand bottles.
If the oil meets the API specs, it will have the API seal. Motor oils that meet the same specs are virtually identical.
In addition, there is a lot of marketing behind motor oils for trucks, old vehicles, SUV's etc. Most of that is baloney.

Pennzoil is owned by shell.... so of course they get they're oil from shell, I forget where valvoline gets they'res..... but they don't refine it.
The difference is basically.... just the additive pack.... some are weaker, some are stronger (castrol and pennzoil have good add packs, while valvoline gets skimpy)
The other difference is base oil.... most conventionals are group II.... highly refined crude, its clean and its a good oil....
Others (like pennzoil) sport a isosyn or purebase, something of that sort.... basically its a group II+ oil..... its highly refined almost to the point of being a synthetic......
Now, group III oils are conventional oils.... but castrol won the suit to call it synthetic... its a hydrocracked petroleum, its perfectly clean... almost as clean as group 4 or 5...
which are true synthetics... group 4 is PAO based oils (Mobil 1).... while group 5 is anything that doesn't fit (redline)....
They're are MANY brands.....
Exxon/Mobil (Superflo, Mobil oils)
Shell (Pennzoil, Quakerstate, and shell)
Chevron (texaco/havoline)
Valvoline (napa store brand)
Warren (supertech, advance autoparts brand)
STP (Jdstreets)
Motorcraft (conoco philips)
Castrol (BP petroleum)
Amsoil (well amsoil is amsoil, they buy from exxon)
Redline (Redline is redline)
Royal purple is royal purple...
etc etc.... usually if you read the back of the bottle, somewhere on there it may tell you... other times it can be as simple as comparing bottles (not always, advance auto and havoline bottles use to look the same, the new style havoline bottles do not)
