Ethanol suitability for Subarus
Most Subarus purchased new in New Zealand since 1990 are capable of running on the ethanol blended fuel now being
introduced to the local market.
However any Japanese domestic specification models which have been imported here second hand (i.e.). second hand
Japanese imports - should not be run on the ethanol blended fuel.
These cars are only suitable for 3 percent blended fuels. The fuel being sold in New Zealand has a 10 percent ethanol
blend.
The 10 percent ethanol blended fuel could cause damage to the fuel line, fuel injector sealing, fuel pump or fuel
regulator of these second hand Japanese imports. The fumes from the blended fuel after combustion can also have a
harmful effect on the catalytic converter, the exhaust gas regulator and the muffler.
Those Subarus which can use the 10 percent ethanol blended fuel have a 17 digit VIN number beginning with either JF1 or
JF2. The VIN number can be found at the bottom of the central door pillar on the passenger’s side of the car or in the
engine bay.
The second hand Japanese imports which should not use the ethanol blended fuel have VIN numbers starting with 7A8
A small number of models sold new in New Zealand cannot use the 10 percent blended fuel. They are.-
Legacy RS, Legacy GT, Legacy GTB, Legacy RSK and Legacy Blitzen from 1990 onwards; the Impreza STI from 1997 onwards and
the Forester STI. They do not have JF1 or JF2 VIN numbers.
Owners who are not sure if they can use the ethanol-blended fuel in their car should consult their nearest Subaru
Authorized Dealer.
