They can make the change but it isn't just turning a switch. Yes, heavy crude is cheaper.

The problem isn't with the refiners. It is with harsh Cali regs that make spending money to update refineries or build pipelines unprofitable.

If they did switch to plentiful light sweet where will they get the light sweet from? You ain't gotz any pipelines to bring the sweet into the state. Most of Cali and Alaska crude is mid to heavy grade. So they have to tanker in the shortfall of heavy from the ME.

You all have built yourself an energy island and the blame rests on your leaderships shoulders.

Switching to light crude refinery tactics would lead to idle refineries because they wouldn't have the light crude to refine.
