Southeast summer grocery/errand OC

[ProfPS]

My wife's '06 chevy 3.5 V6 grocery/errand runner is due for a 4k mi OC [OLM <10%]. Which would you choose from my stash of 5w30 SN oil for a southeast with traffic stop-and-go 4k mi OC [temps have already been in the 90's]: Pennzoil Conventional, Quaker State Conventional, Havoline DS, or Mobil Super 5000?

Any of those will do just fine.

 

[ProfPS]

Thanks. Do you have a preference out of the four for this application?

Pennzoil conventional. Just because I like it and it has never let me down.

I like Mobil Super 5000 out of those. Though I rarely use conventional.

If most trips are less than 10 miles the oil temperature may never get above 180-190F, you can use 1 grade thinner.

Pennzoil conventional for summer OCI - any of the others for the rest of the year . The reason is the Pennzoil conventional has the better add packs and perhaps a better base oil to handle the tougher Summer conditions . All the others would be a close second and are fine conventional oils as well .

PYB because of the high level of moly.
Quaker State Conventional cause it also hasa dose of moly, but less

Mobil-not even in contention, maybe for the lawnmower
