Yes, 20 and 7 are the 'rule of thumb' but doesn't include home heating oil.
There's propane, butane, asphalt, coke etc etc etc in there, too.
It all depends on where and what the specific refinery is reforming for and if they are focusing on gasoline.
Here is the average breakdown of refined products for 2000:
