Gasohol fuel: how to tag?

Beddhist · January 23, 2011, 1:04pm

Hi,

Here in Thailand we have 4 types of petrol:

Unleaded 91 and 95
Gasohol 91 and 95. I can tag this as E10.

However, if a gas station has only Gasohol 95, but not 91, how can I tag this?

Regards,
Peter.

Like this maybe?
Gasohol 91 → 91E10, Gasohol 95 → 95E10

How about:

fuel:e10=yes
e10=octane_91

or

fuel:e10=octane_91

I guess it needs to be standardised or it won’t be searchable.

What octane measurement method is used on openstreetmap.org ?

I’d say the locally used one. Wouldn’t make sense to tag a station that shows 95 RON with 85 MON when no one could interpret that. I mean the purpose of the tagging should be to identify the correct quality for your car and not some scientific study on petrol distribution.
