Jet fuel, diesel, and heavy oils. The crack spread for diesel is probably the best indicator we have. But I agree it is hard to determine exactly how profitable they are.
But don't forget that PBF has only 10% jet fuel. They probably have some other stuff too. But 80% is gasoline. And that applies to most refineries (except the 2 polish refineries that I pointed out in the past). A lot of companies don't even have jet fuel.
So this is a world of a difference with BDCO. The price for jet fuel and diesel is the best indicator we have. And we are in a very sweet spot compared to those other refineries.
