[snip of economics]
Why do we have unrefined fuel when the refining process adds only Cr 7 per dTon to the production cost?
And...you've just touched on what this thread is all about...
From another angle, fuel purifiers on starships are relatively cheap according to Book 5. The cost savings in refined vs. unrefined fuel alone covers the cost of the processor and the lost revenue in cargo space due to the unit's size.
Since that is true in the Traveller universe (and it is because Book 5 gives us that), then why do most civilian craft not have fuel purifiers?
Your comment is: Why is refined fuel offered at all if the price of refining is so cheap?
My answer to that would be: Because there's a market for refined fuel. Most civilian ships don't have fuel processors, and if they use unrefined fuel, run the risk of misjump.
Which leads us back to my original question starting this thread: Why don't civilian craft normally have fuel processors?
What we need is a good, logical, interesting handwave that answers this for us.
Maybe it's government regulation?
Maybe it's that not only is a fuel processor needed (which is cheap), but also specially designed drives are also needed (which is mentioned in Book 2) to run refined fuel that the ship processes itself?
Since some of the drives in Book 5 are so much more expensive than their Book 2 counterparts, this makes some sense--that when you add a fuel processor you also need a custom built and very expensive drive to run the fuel it processes.
This would lend itself to the idea that fuel "purified" with a starship fuel purification plant is of better quality than unrefined fuel...but also of inferior quality to refined fuel (the actual refining process requires a much larger system than what can be accomplished economically on a starship? Fuel Purification Plants are "miniature" and inferior versions of the large planet-bound fuel refineries?). Yet, the processed fuel is not of such an inferior quality that it induces misjumps.
Three grades of fuel?

This is starting to make some sense.
