So just tag it as fuel:octane_87, fuel:octane_89, etc. Not Sure about
the kerosene. fuel:kerosene=yes would seem logical but I'm not sure
what the non-taxable use has to do with things.

there are two grades of kerosene in the US, K-1 and K-2. i for the most part
only see K-1 around (which is the low sulfur variant and so much preferred).

kerosene=yes if you don't know the rating, otherwise
kerosene=k1
kerosene=k2

i understand that in the UK, they have grades c1, c2, etc, which fits right in
with this scheme

for diesel, there is a cetane rating, as well as a grade. grade would be interesting
to know, but because stations have been known to change off depending on
season and climate, keeping the information up to date would be insane. knowing whether the diesel is low sulfur would have been interesting a few years ago, but most of the world is now using low sulfur diesel for all road going applications.
