You wake up and you are made the supreme ruler of the United States. Your authority is absolute. Your first order of business is to choose one oil that will be the only product available for all roadgoing vehicles. No variations, no different weights. My suggestion would be that you choose the oil that would work the best for most peoples in most vehicles, but maybe you have different priorities. Share your choice and any rationale if you feel like it.
I'll start: Castrol GTX Full Syn 0W20. I think that this would be usable by most vehicles on the road and is reasonably economical. Apologies to long-haul truckers.
