Fuel specification
The fuel must comply with national and international standards for commercially supplied fuels, such as:
EN 590
(with nationally adapted environmental and cold weather requirements)
ASTM D 975 No 1-D och 2-D
JIS KK 2204
Sulfur content:
Complying with legal requirements in each country. If the sulfur content exceeds 0.5 weight-
percent, the oil change intervals shall be changed, refer to
Extremely low sulfur content fuel (urban diesel in Sweden and city diesel in Finland) can cause a loss of up to 5
% of power and an increase in fuel consumption of about 2-3 %.
Biodiesel (FAME)
Vegetable oil esters (Fatty Acid Methyl Esters, FAME), also called "biodiesel", are increasingly available as a
blending component in diesel fuels. Volvo Penta accepts the same FAME content as in major on-road fuels EN
590 and ASTM D975; i.e. today up to 7%, without any specific additional service requirements. Please contact
your Volvo Penta Dealer for futher information.
For engines produced after 1 Jan 2009 Volvo Penta accepts, with specific service requirements,
• max 30% FAME blend (FAME component in accordance with EN 14214 and diesel fuel in accordance with
EN 590)
• max 20% FAME blend (FAME component in accordance with ASTM D6751 and diesel fuel in accordance
with ASTM D975)
NOTICE!
Higher FAME blends will negatively impact performance, emissions and fuel consumption. Furthermore the func-
tion of the Stage 3B engine exhaust aftertreatment system will be negatively affected.
NOTICE!
Engines for emergency applications, e.g. genset standby, must only run with market diesel fuel with minimum
FAME content.
NOTICE!
Tier 4i engines must only run with market diesel fuel.
NOTICE!
In case of cold starting problems shift to diesel fuel. Do not to use FAME below -10°C.
NOTICE!
Raw vegetable or animal oils do not meet EN 14214 and are not allowed as fuels or fuel blending components.
