Yes to us in Australia the standard dealer bulk is usually something like a mineral 15W40 (SN and A3/B3) or a semi-synthetic 10W40 (SN and A3/B4 - higher TBN). That stuff goes into everything.
For our friends in North America is more likely to be a mineral 5W30 that is SN and GF-5.
But things are changing in Oz and a Dexos 5W30 is becoming more common. I now regularly see Shell Helix Ultra 0W20 on the shelves in my local auto store.
I was fueling up at a small garage across town the other day. The mechanic had two bays / hoists and being a small place their bulk oil was all in 20L drums on the shop bench. They had three full synthetic Castrol oils ( Edge or Magnatec SP) with the choices being
- Edge 5W30 A3/B4 (SL - high zinc, A3/B4, MB 229.5, BMW LL-01) high SAPS and high TBN.
- Magnatec 5W40 (SN, ACEA C3, Dexos2)
- 5W30 low SAPS C3 that was VW 504 / 507 (Edge or Magnatec, can't recall which)
All very good, full synthetic Castrol oils. Not an ILSAC oil in sight. Not a mineral oil in sight. Small standalone converted house that you could easily see into and around. Had a small VW on one hoist and a large Toyota LandCruiser on the other. Both very new looking.
