meet seasonal air quality standards, some
areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxy-
genated" fuels. However, the specified octane
ratings must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to
22% MTBE/ETBE by volume may be used.
Methanol
Do not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.

Octane rating
Volvo requires premium fuel (91 octane
higher) for all T5, T6 and T8 engines, and rec-
ommends AKI 93 for optimal performance
and fuel economy. See decal examples in
illustrations 1 and 2.
For optimal performance, Volvo recommends
premium fuel (91 16 octane and higher) for T4
engines. However, engine reliability should
not be affected as long as 87 octane
higher is used. See decal example in illustra-
tion 3.
