2.3 FUEL SYSTEM

Diesel fuel
Diesel fuel must meet the specifications 

according to EN 590. At extremely low 

temperatures amd exclusively in an emergency, 

(for example, breakdown), a specific quantity of 

petroleum (maximum 20%) or a flow improver 

may be added.

However, if this is PROHIBITED BY LAW, a 

maximum of 20% unleaded petrol may be added.

Explanation: For BE and CE engines, fuel 

additives are not permitted.

Fuel should have a lubricity effect according to 

the requirements below ("lubricity standard"):

Biodiesel
Biodiesel (according to standard EN 14214) is 

permitted for the following DAF vehicles:

-

CF75/85 from chassis number 0E552890

-

XF95 

Sulphur content

Oil change interval

> 0,2%

halve interval to max. of 25,000 km

test method:

HFRR according to standard CEC-F-06-A96

test value:

< 460 µm

Restrictions:
Oil changing interval:
Is to be halved compared with the standard 

changing interval. Extended changing intervals 

are not allowed.

Oil and fuel filter replacement interval: 
Halve.

Cab heater: 
The D1LC compact and D3LC compact air heater 

versions are suitable for biodiesel.

The Hydronic 10 and D2 Airtronic water heater 

versions are not suitable for biodiesel.

Note:

Biodiesel has dissolving characteristics so that 

the change from diesel to biodiesel may cause 

deposits in the fuel system to dissolve and 

thereby clogging the filter. When changing from 

diesel to biodiesel it is wise to check the filters 

after 1 or 2 tank fillings and to replace any 

clogged filters. At low temperatures biodiesel 

may cause problems such as clogging of filters.

LPG fuel
The EON number (Engine Octane Number) must 

be a minimum of 93.5.

(not to be confused with the RON number 

(Research Octane Number)).

3.1 GEARBOX OIL FOR ZF GEARBOXES

The oil specification overview is related to the 

maintenance schedules as stated in the 

maintenance manuals.

The permitted oil products are listed in the 

appended ZF lubricant specifications (TE-ML 02 

and TE-ML 14); the viscosity classes and 

suppliers are listed as well.

The currently applicable specifications are 

appended; consult the ZF website, 

WWW.ZF.COM, for other products and approved 

suppliers.

Explanation of overview
V = may be used.

ZF gearbox applied in the vehicle series: 
45/55

Explanation: Use of class 02B or 02H oil is 

advised against as there may be an increase in 

the required gear-changing forces at low 

temperatures.
