INTRODUCTION
Oil, Straight Vegetable Oil (SVO), or more generally unrefined vegetable oils used as motor fuel are NOT APPROVED
at any blend in any CASE IH product.
NOTICE:
Any engine and fuel injection equipment fitted to a CASE IH vehicle found to have run with any blend of
NON-APPROVED fuel (fuel not fulfilling the specification described in the requirement
ASTM D6751
) will no longer
be covered for Warranty by CASE IH.
Biodiesel fuel usage conditions
You must stringently follow the biodiesel fuel usage conditions. Incorrect application of the biodiesel fuel usage con-
ditions could lead to severe damage to the engine, fuel injection equipment and aftertreatment system.
The main concerns related to operation with biodiesel fuels are:
• Filters and injector blockage caused by poor fuel quality.
• Wear and corrosion of internal components due to water content, which affects lubricity.
• Deterioration of some rubber sealing compounds in the fuel system.
• Biodiesel oxidation, which can lead to the formation of deposits that can harm the fuel injection system.
NOTICE:
Any problem in the engine fuel injection equipment associated with non-compliance to the following condi-
tions for biodiesel fuel handling and maintenance will not be covered for Warranty by CASE IH.
Purchase biodiesel fuel from a trusted supplier who understands the product and maintains acceptable fuel quality.
It is highly recommended that you use biodiesel from BQ 9000 accredited suppliers to maintain the quality and con-
sistency of the fuel. The BQ 9000 Quality Management Program is accredited by the National Biodiesel Board for
producers and marketers of biodiesel fuel. See the National Biodiesel Board website at www.biodiesel.org for more
information.
The use of biodiesel blends above B5 through B20 will not void the CASE IH warranty as long as the following con-
ditions for biodiesel fuel handling and maintenance are stringently followed:
Biodiesel fuel must be pre-blended by the supplier. Mixing biodiesel fuels on-site can result in an incorrect mixture
that could damage the engine and/or fuel system.
For machines using Tier 4b engines with an exhaust aftertreatment system:
1. If the biodiesel blend stock to
ASTM D6751
is used, special precautions need to be taken to insure that it
fully complies with the following special requirements:
• Group I Metals content ( Potassium) is ≤
5 mg/kg
per
EN14538
as specified in the biodiesel spec.
• Group II Metals content (C Magnesium) is ≤
5 mg/kg
per
EN14538
as specified in the biodiesel spec.
• Phosphorus content lower than specified is a mandatory requirement. Phosphorus must not exceed
4 mg/kg
per
ASTM D4951
.
2. The resulting greater than B5 through B20 blend must not exceed
1 mg/kg
for Group I Metals ( Potas-
sium) and for Group II Metals (C Magnesium).
NOTICE: For machines using Tier 4b engines with an exhaust aftertreatment system in regions where the
biodiesel blend stock is supplied to the ASTM D6751 standard, it is essential that evidence of compliance
to the special limits for Group I Metals, Group II Metals and the reduced phosphorus content specified
above be obtained on every delivery of fuel from the fuel supplier. Failure to comply with this requirement
can result in damage to the catalyst of the aftertreatment system which will not be covered under warranty.
NOTICE:
CASE IH may void your warranty if the problem is associated with poor fuel quality due to improper blending.
It is the responsibility of the fuel supplier and/or yourself to ensure the right type of fuel and blend is delivered and
used.
Maintenance intervals
For machines using the all electronic engines with a high pressure common rail fuel system, the engine oil and filter
change interval is reduced to
250 h
when using biodiesel blends greater than B5 up to B20. Please refer to the
maintenance intervals specified in the Operator Manual for all engines.
