1998 VOLVO C70 fuel cap

Fuels containing up to 10% ethanol by volume may be used.
Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
Refueling
The fuel filler cap is located inside the fuel tank cover on the right rear fender.
NOTE: The fuel tank cover is locked and must be popped open using the control on the driver's door (see page 37).

Open fuel filler cap slowly during hot weather conditions.
When filling, hang the cap on the special bracket on the inside of the fuel tank cover.
NOTE: Turn the ignition off or to position I when refueling. If the ignition is on, an incorrect reading could occur in
the fuel gauge (low fuel level will be indicated).
After filling the tank, install the cap and turn until a "click" is heard.
The fuel tank is designed to hold approximately 18.4 US gal. (70 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank will be somewhat less than
the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning
light comes on.
CAUTION:
Do not refuel with the engine running. After refueling, close the fuel filler cap by turning it clockwise until it
clicks into place.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. Use only Volvo original or approved fuel filler caps.
CAUTION: Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted
surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasoline containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under
the New Vehicle Limited Warranty.

CAUTION: Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or
lubricated. The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the
hub caps.
pg. 84 Spare tire
Temporary Spare (certain models)
The spare tire of your car is what is called a "Temporary Spare". It has the following designation: T115/70 R15 or
T125/90R15.
Recommended tire pressure (see decal on fuel filler flap) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire a new one can be purchased from your Volvo retailer.
CAUTION: The car must not be driven with wheels of different dimensions or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission.
WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Roadholding, etc., may be
affected with the "Temporary Spare" in use. Do not, therefore, exceed 50 mph (80 km/h).

Oil quality

Meeting API specification SG, SG/CD, SH or Energy Conserving (EC) II
For best fuel economy and engine protection, consult with your authorized Volvo retailer for recommended oils. Oil
with a different quality rating may not provide adequate engine protection. Synthetic oils complying with oil quality
requirements are recommended for : driving in areas of sustained temperature extremes (hot or cold), when towing a
trailer over long distances or for prolonged driving in mountainous areas.
Extra oil additives must not be used unless advised by an authorized Volvo retailer.
NOTE: SAE 15 W -40 oil should only be used in extreme operating conditions such as trailer towing in sustained
ambient temperatures over 104° F (40° C). However, SAE 10W -30 synthetic oil would be a better alternative in such
conditions.
SAE 15W-30 should not be used under normal operating conditions.
