I sure wouldn't critisize using synthetic or even Mobil One. But, I sure don't know what you got against bulk. Do you just like throwing away plastic containers with minor quantities of oil into the landfill.
Personally I think they should make everyone pick up their oil in their own container, sort of like grocery shopping in europe. We get almost all our lubricants in bulk. Do you think they pulled that M One out of the ground in that little bottle? It was all in bulk at one time.
