For non-turbo models, the 2010 Legacy uses 87 octane gas or higher. For turbo models, the Legacy uses 93 octane gas or higher. Subaru states that if 93 octane gas is not available, 91 octane can be used, but engine performance may be affected. Subaru also notes that although it should be avoided, 87 octane can be used temporarily for the turbo engines until the next fill-up.
