The potion rules stipulate that the drinker is both the caster and the target for the potion, and that spells with a range of Personal are not valid options for making a potion. How does this work with spells that are centered on the caster but have a non-personal range?
Examples include Bless (The caster and all allies within a 50-ft. burst, centered on the caster), Line in the Sand (Range: 5-ft. burst centered on you) and Obscuring Mist (cloud spreads in 20-ft. radius from you, 20 ft. high).

It's not an area spell. Just a spell that affects multiple people in an area. There is a difference. Potions of fireball aren't allowed for instance. But in drinking that, yes, only you gain the benefit. Not ideal, but level 1 spells like bless are cheap so not terrible.
Aiming a Spell.....
You must make choices about whom a spell is to affect or where an effect is to originate, depending on a spell's type. The next entry in a spell description defines the spell's target (or targets), its effect, or its area, as appropriate.
BLESS
School enchantment (compulsion) [mind-affecting]; Level cleric 1, paladin 1
Casting Time 1 standard action
Components V, S, DF
Range 50 ft.
Area The caster and all allies within a 50-ft. burst, centered on the caster..
The spell is not cast on the caster. It is just centered on him.

When you create a potion, you make any choices that you would normally make when casting the spell. Whoever drinks the potion is the target of the spell.
A potion of bless would target the drinker. However, the selection of allies is the choice of the brewer. If someone in your party brews it, they can designate a set of people. Otherwise, I would assume self only.
A potion of haste would only affect you since the feat changes the target line.

Bless is an area spell that affects all allies in an area around the caster.
As an area spell, it is not a targeted spell. Therefore, it would not be a viable spell for a potion or oil.
A potion or oil can be used only once. It can duplicate the effect of a spell of up to 3rd level that has a casting time of less than 1 minute and targets one or more creatures or objects.
As wraithstrike pointed out above, a spell has a target(s), effect, or area, and they are aimed and treated differently.

So bless affects up to 100 allies in an area when cast by a first level cleric? (Goes to a bar and picks up an ugly mob) Now I just need a firemage and a Paladin to find a building with some evil in it. :)
I'm saying sarcastically that bless is broke, yo!
If you go death star with small & medium creatures, you can get up to 4169 allies in a single bless. [Using real distance, not PF approximation of diagonals.]
If you calculate with a 3D diagonal then a 2D one then a strait line, it is 3173. This is at 1.5* for 2D diagonal, and 1.75* for a 3D diagonal.
Even so, that is not a mob, but a crusade.
