GENERAL 19 FUEL, LUBRICANTS AND COOLANTS FUEL (DIESEL) Normal grade BS IV compliant 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. Ambient temperature Summer Supplementary up to Deg. C Percentage Summer grade diesel Supplementary fuel Up to 0 100 0 0 to -10 70 30 -10 to -15 50 50 Care should be taken that diesel and supplementary fuel are thoroughly mixed before filling. Ambient temperature Summer Supplementary up to Deg. C Percentage Winter grade diesel Supplementary fuel Up to -15 100 0 -15 to -20 70 30 -20 and below 50 50 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. NOTE: 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. Recommended Fuel Specification for engine Parameter Unit BS III Cetane Number (min) CN 51 Sulphur content mg/kg 50 Lubricity (HFRR) micron 460 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: 1. Approx. 4 Liters for Petrol 2. Approx. 5 Liters for Diesel 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. NOTE: We strongly recommend refilling your car’s engine coolant only at a TATA Authorised service centre.
