Here's what we have off the top of my head...
- 5W30 conventional bulk (equivalent to AC Delco 12345610 / 10-9060)
- 5W30 Dexos1 full synthetic bulk
- 0W20 Dexos1 full synthetic bulk
- Mobil 1 5W30 quart bottles
- Mobil 1 0W40 ESP Dexos2 quart bottles (not much)
- AC Delco 5W30 full synthetic Dexos2 quart bottles
- Mobil Delvac 15W40 quart and gallon bottles, but billed by the quart
Those are the GM oils used on GM vehicles.
We do have a drum of 5W20 conventional for used cars that is just billed as "5W20," other than that some random bottles of 10W40 for the parts trucks and stuff.
