RECOMMENDED MATERIALS
1. GENERAL
To insure the best performance, always use the specified oil, gasoline, adhesive, sealant, etc. or a substitute of equivalent quality.
2. FUEL
Always use gasoline of the same or higher octane value than specified in the owner's manual. Ignoring the specifications below will result in damage or poor performance of engine and fuel injection system. To gain proper performance, always use specified gasoline.
UNLEADED GASOLINE
In order to reduce air pollution, use unleaded gasoline for the vehicle equipped with catalytic converter. Using leaded gasoline may damage the catalytic converter.
3. LUBRICANT
Use the lubricants shown in the table below, or equivalent. See the table below to choose the correct SAE viscosity.
4. FLUID
Use the fluids specified in the table below. Do not mix two different kinds or makes of fluid.
5. COOLANT
Use the coolants specified in the table below to protect the engine.
6. REFRIGERANT
Standard air conditioners on Subaru vehicles use HFC134a refrigerant. Do not mix it with other refrigerants. Also, do not use any compressor oil except for DH-PR.
7. GREASE
Use grease and supplementary lubricants shown in the table below.
8. ADHESIVE
Use the adhesives shown in the table below, or equivalent.
9. SEAL MATERIAL
Use the seal material shown in the table below, or equivalent.
