FUEL, LUBRICANTS AND COOLANTS
FUEL (DIESEL)
High Speed diesel conforming to IS1460 or EN
590 or equivalent is recommended to be used as
fuel.
At very low temperature, fluidity of diesel may
become insufficient due to paraffin separation. It is
therefore necessary to mix supplementary fuel
with summer or winter grade diesel. Ratio for
mixing of supplementary fuel and diesel are
shown in the table.

WARNING:
Do not mix gasoline or alcohol with diesel. This
mixture can cause explosion.
Do not use premium diesels available in the
market for example extra premium / Turbojet etc.
NOTICE:
Where oxidation catalytic converter is fitted, it is
mandatory to use Diesel fuel with Sulphur
contents as under. Use of any other diesel fuel
can increase the pollutants.

FUEL (PETROL):
Unleaded regular grade petrol conforming to IS
2796:2008and BS IV specification and RON not
less than 91 is recommended. It is always
recommended to use correct fuel to get optimum
emission performance.
NOTE
Always use petrol of a correct specification in a
vehicle fitted with catalytic converter. Even single
fill of leaded petrol will seriously damage the
catalytic converter.
LUBRICANTS AND OILS:
Please use only recommended grades for
good performance.
DO NOT mix grease of different brands and
optional grades. Replace old grease completely. The
oil change periods recommended in maintenance
schedule should be adhered.

Coolants Qty:
Approx. 5.4 Liters
Presence of dirt in coolant chokes up passages in
radiator, cylinder head and crankcase, thereby
causing overheating of engine.
To prevent rust formation and freezing of coolant
inside the passages of radiator, crankcase and
cylinder head use premixed coolant as
recommended.
It is recommended that the entire cooling system
should be drained and filled with fresh premixed
coolant.
Engine coolant antifreeze coolant as per class
II/JIS K2234.
