Calumet. They Make POE.
As far as actual engine oils it is largely irrelevant. Group 3,4,5 it makes no difference.
a good motor oil uses many different basestocks to create an optimal package. What is important is a good blend.
Indeed, you can make a really terrible oil with group 5 or a really top of the line oil with group 3, it all depends on how it's made and what's put into that base oil.
If I get a group 5 base oil and try to run it with insufficient additives it will sludge up.
If you are new to motor oil and want to find good ones look at manufacturer approvals and builder approvals to get a good idea of the performance of the oil.
Here's some good ones you might want to see on the jug.
VW 507.00
MB 229.5
Dexos 1/2
BMW LL01/LL04
Ford M2C948
ACEA A5/B5
Porsche A40
Of course you want bare minimum specs like ILSAC GF5 or API SN for many popular applications but the others in addition to that mean something
Agreed on looking for specs on the bottle, but A5/B5?! That's thinner than water and won't protect a thing
. A3/B4 is a much better choice
