Mogas deliveries from Europe could last all winter.  I'm 10 yrs out of date and a few refineries there have bit the dust since, but back in the dark ages, we stocked European components in every tank we could find against spring price spikes in the US (esp. California).

At these mogas cracks ($1.87=$78.5-$62 =$16.5!!!) any refiner will keep runs at max till doomsday.  Winter cracks used to be about $3 with heat about $4....

How much mogas is really coming out of tank from the stragetic reserves?  Much of the planned releases from the SPR never happened as no one wanted/needed it.
