Volvo Penta TDTAD Series Engine Data

Lubrication System

Oil change intervals can vary between 150 and 500 hours depending on the quality of the lubricant and the sulphur content of the fuel. Note that the oil change interval should never be longer than 12 months.

If longer intervals are required than those stated in the table below, the condition of the oil must be tested regularly by the oil manufacturer.

1) If sulphur content is > 1.0% by weight, use oil with TBN > 15.

2) Lowest recommended oil type, engine oil of an higher type can always be used.

3) API: CG-4 or CH-4 are acceptable in markets outside Europe, instead of ACEA E3.

Viscosity

Select the viscosity according to the table.

The temperature values refer to stable ambient temperatures.

* SAE 5W/30 refers to synthetic or semi-synthetic oils.

Fuel System

Fuel specification

Fuel must comply with national and international standards for commercially supplied fuels.

NOTICE! Bio-diesel according to EN 14214, kerosene and light fuel oil may not be used.

The following fuel standards are approved:

EN 590 (with nationally adapted environmental and cold weather requirements)

ASTM D 975 No 1-D and 2-D

JIS KK 2204 (may only be used if lubricity corresponds to EN 590)

Sulfur content: According to current national legislation. If the sulfur content exceeds 0.5 weight-percent, the oil change intervals must be amended;

Extremely low sulfur content fuel (EC1 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 %.

General fuel requirements

The fuel quality is essential for engine function, durability and emission compliance. Only fuels meeting relevant legal requirements and national and international standards shall be used; such as European EN590 diesel and North American ASTM D975 diesel.

Usage of fuels or fuel blends that do not comply with the below specifications given in this document is not allowed and Volvo Penta will not accept warranty in case of fuel related engine damages.

Diesel fuel requirements

An insufficient cetane number (“ignitability”) leads to poor startability and increased exhaust emissions. Requirement; cetane number min 45.

Insufficient density and viscosity will reduce the power and increase the fuel consumption.

Excessive density and viscosity will endanger the durability and function of the fuel injection equipment. Requirement; viscosity 1.5-4.5 mm2/s (cSt) at 40 °C and density 800-860 kg/m3 at 15 °C.

Sufficient fuel lubricity is essential to protect the fuel injection system against excessive wear. Requirement; wear scar max 520 μm in the HFRR test (ISO 12156)

Excessive sulfur content will increase emissions and give engine corrosion and wear.

Requirement; The max allowed sulfur content is5000 ppm, with the restriction that oil of quality VDS 3 must be used for sulfur content above 3000 ppm.

Water will give corrosion and wear of engine parts and enables microbial growth in the fuel tank.

Organic contaminants (bacteria, fungi etc.) can block fuel filters and inorganic contaminants (dust, sand) can cause severe damage to the fuel injection system.

Requirement; max allowed water content 200 ppm and max allowed total contaminant content 30 ppm.

Cold flow properties are determined by the cloud point (the temperature when wax crystals start to fall out) and the CFPP (cold filter plugging point). The oil companies are always responsible for providing fuels with the correct cold flow properties for any time of the year.

FAME (“biodiesel”)

Requirement;The max allowed FAME content is 30%, if the FAME part complies with EN14214 and the diesel complies with EN590, with specific service requirements as below:

• Oil change and oil-filter replacement intervals must be halved.

• Fuel filters shall be changed at every oil change and fuel filter housings and seals shall be changed annually.

• A fuel heater should be used due to the high viscosity of FAME at low temperature.

In order to avoid starting problems FAME should not be used below -10°C.

• A fuel filter with water separator must be used since FAME is hygroscopic.

• When shifting from regular diesel fuel to higher FAME content the fuel tank must be cleaned and the fuel

filter must be replaced after 50 h.

• If the engine has not been used for a period over 4 weeks the tank and fuel system must be flushed clean by running the engine on at least one full tank of regular diesel.

NOTICE! Engines for emergency applications, e.g. standby genset , may only run with market diesel fuel with minimum FAME content.

Paraffinic fuels (“Synthetic Diesel”) - HVO and GTL

HVO (Hydro-treated Vegetable Oil) are renewable, and GTL (Gas-To-Liquid) are fossil, paraffinic fuels. Usage of paraffinic fuels will give lower emissions, but also marginally higher fuel consumption.

NOTICE! Volvo Penta approves usage of neat HVO and GTL that complies with EN 15940, as well as HVO and GTL blends into diesel fuels complying with the quality requirements above.

Kerosene (“Jet fuel”)

Kerosene has low cetane number, low viscosity, low lubricity and high sulfur content compared to diesel fuels.

NOTICE! Kerosene F-63 can be used, but Volvo Penta does not guarantee emission compliance. F-34/JP8 and F-44/JP5 can also be used, but only with lubricity additives to ensure max 520 μm wear scar in the HFRR test (ISO 12156).

Additives

The oil companies shall always ensure that their fuels meet relevant requirements and are fit for their purpose. Their responsibility includes any use of additives for proper engine performance and function.

NOTICE! It is not allowed to add secondary treatment additives ("diesel boosters"), lubricants, gasoline or alcohol into the fuel tank.

1) The coolant volumes listed apply to the use of Volvo Penta original coolants

2) engine only

Coolant

Volvo Penta Coolant VCS and VCS Ready Mixed (yellow) are based on Organic Acid Technology, OAT.
