Editing Key:fuel price

The {{Fact|fuel_price}} [[fact]] provides information about the fuel prices at a given station.

== Associated properties ==

Fuel price requires the following additional properties:

* [[currency]]
* [[volume]]

== Fuel types ==

The fuel_price fact requires a [[fuel type]] specifier.

=== Gasoline ===

| 87 octane

All gasoline fuels can have an optional ethanol specifier.

|-
| e100 (pure ethanol)
| {{Fact|fuel_price|subkey=87:e100||1.339}}
|}

=== Diesel ===

{| class="wikitable" border="1" cellspacing="0" cellpadding="4"
|-
! Type
! Examples
|-
| Standard diesel
| {{Fact|fuel_price|subkey=diesel||1.389}}
|-
| Premium diesel
| {{Fact|fuel_price|subkey=diesel:premium||1.509}}
|}

'''Note:''' Premium diesel (Shell V-Power, BP Ultimate, Total Excellium, etc.) uses the same base diesel fuel as regular diesel but with enhanced additive packages, higher cetane ratings (53-55 vs 51), and cleaning agents for improved engine performance and protection.

All diesel fuels can have an optional biodiesel specifier.

{| class="wikitable" border="1" cellspacing="0" cellpadding="4"

! Type
! Examples
|-
| b0 (pure petroleum diesel)
| {{Fact|fuel_price|subkey=diesel:b0||1.389}}
|-
| b5
| {{Fact|fuel_price|subkey=diesel:b5||1.389}}
|-
| b7
| {{Fact|fuel_price|subkey=diesel:b7||1.389}}
|-
| b20
| {{Fact|fuel_price|subkey=diesel:b20||1.389}}
|-
| b100 (pure biodiesel)
| {{Fact|fuel_price|subkey=diesel:b100||1.389}}
|}

=== Special Fuels ===

{| class="wikitable" border="1" cellspacing="0" cellpadding="4"
|-
! Type
! Examples
|-
| LPG (Liquefied Petroleum Gas)
| {{Fact|fuel_price|subkey=lpg||2.199}}
|-
| Hydrogen
| {{Fact|fuel_price|subkey=hydrogen||12.99}}
|-
| E85 (85% Ethanol Flex Fuel)
| {{Fact|fuel_price|subkey=e85||2.899}}
|}

'''Note:''' E85 should be used as a special fuel when the octane value is unknown or not advertised at the fuel pump. If the octane rating is known (typically 105-115 range), use the specific octane with e85 ethanol specifier instead (e.g., <code>fuel_price:105:e85</code>).
