I think that it is safe to say that there is something of everything 
somewhere - even if not currently mapped.  A few years ago a local 
petrol station hit on the interesting combination of "red diesel* + 
leaded".  After working down this list

https://taginfo.geofabrik.de/europe/britain-and-ireland/search?q=fuel

and looking at combinations, I currently use this logic:

https://github.com/SomeoneElseOSM/SomeoneElse-style/blob/master/style.lua#L1499

to decide whether something should be displayed on a map as "regular 
fuel", "electricity", "waterway fuel", "regular fuel and electricity", 
"LPG" or "hydrogen" (in UK/IE).  Note that consideration of aviation and 
water usage means looking at vending too - but you may want to just 
ignore those.

Best Regards,

Andy
