■Fuel*1: For details, refer to "Fuel" P223.■ Engine OilFor the checking, adding and replacing procedure or other details, refer to "Engine Oil" P346.NOTEThe procedure for changing the engine oil and oil filter should be performed by a properly-trained expert. It is recom-
mended that you have this service performed by your SUBARU dealer.
▼ Approved engine oil
Always use the SUBARU approved engine oil. For fu rther details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
▼ Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
 In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommend ed viscosities and applicable temperatures.Compression ratio 12.5 : 1

Tire Information
398Cord separation
The parting of cords from adjacent
rubber compounds.
 Cracking
Any parting within the tread,
sidewall, or inner liner of the tire
extending to cord material.
 Curb weight
The weight of a motor vehicle with
standard equipment including the
maximum capacity of fuel, oil and
coolant, and if so equipped, air
conditioning and additional weight
optional engine.
 Extra load tire
A tire designed to operate at higher
loads and higher inflation pressure
than the corresponding standard
tire.
 Groove
The space between two adjacent
tread ribs.
 Innerliner
The layer(s) forming the inside
surface of a tubeless tire that contains the inflating medium within

the tire.
 Innerliner separation
The parting of the innerliner from
cord material in the carcass.
 Intended outboard sidewall
(1) The sidewall that contains a
whitewall, bears white lettering or
bears manufacturer, brand, and/
or model name molding that is
higher or deeper than the same
molding on the other sidewall of
the tire, or
(2) The outward facing sidewall
of an asymmetrical tire that has a
particular side that must always
face outward when mounting on a
vehicle.
 Light truck (LT) tire
A tire designated by its manufac-
turer as primarily intended for use
on lightweight trucks or multipur-
pose passenger vehicles.
 Load rating
The maximum load that a tire is
rated to carry for a given inflation
pressure. 
Maximum inflation pressure
The maximum cold inflation pres-
sure to which a tire may be inflated.
 Maximum load rating
The load rating for a tire at the
maximum permissible inflation pres-
sure for that tire.
 Maximum loaded vehicle
weight
The sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight
(d) Production options weight
 Maximum permissible inflation
pressure
The maximum cold inflation pres-
sure to which a tire may be inflated.
 Measuring rim
The rim on which a tire is fitted for
physical dimension requirements.
 Normal occupant weight
150 lbs (68 kg) times the number of
