octane VOLVO C70 2001 Owners Manual

Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.

Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).
Gasoline containing alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol

The following should be checked regularly: *
1 Washer fluid reservoir should be filled with water and solvent (wintertime: windshield washer anti-freeze). See
page 115.
2 Coolant level should be between the expansion tank marks. Mixture: 50% anti-freeze and 50% water. See page 116.
3 Power steering - When cold, the level must not be above the COLD mark and when hot it must not be above the
HOT mark. Top up if the level drops to the ADD mark with ATF fluid. See page 114.
4 Engine oil level should be between the dipstick marks. The distance between the marks represents approx.
1.6 US qts (1.5 liters). See page 112.
5 Brake fluid - check, without removing the cap, that the level is above the MIN mark. Use brake fluid DOT 4+. See
page 114.
* Engine oil should be checked each time the car is refuelled.
