CARING FOR MILEAGE

Stop the drop that leaks

Petrol leak at a rate of one drop per minute accumulates to 5,25,600 drops a YEAR! That is, 35 ltrs of Petrol.
O Petrol leaks cause raw petrol smell. Get the leaks arrested immediately.

○ Wrong grade or adulterated petrol does not burn fully and results in heavy smoke, high rate of carbon deposition in cylinder and exhaust system and low mileage.
O Wrong grade and inferior quality oils do not lubricate well. The moving parts wear prematurely.
○ Always use recommended fuel (unleaded > 87 octane petrol) and oils only.

Ride at cost effective speed

○ Cost effective speed (in top gear) is 45 to 50 Km per hour.

Both lower and higher road speeds cause low kilometers per litre of petrol.

Perform preventive Maintenance as per recommendations

Regular preventive maintenance ensures :

○ Correctly inflated tyres.
○ Fasteners tightened to correct torques.
○ Freely moving engine & transmission components.
○ Properly tuned and adjusted engine.

Cut off needless low idling

Ten minutes of low idling wastes 70 ml. of petrol. So cut off the engine when you know you have to wait for one minute or more.

Stop

○ Revving : Ten revvings wastes 20 ml. of petrol

CARING FOR MILEAGE

ROYAL ENFIELD

○ Racing starts :Ten racing starts wastes 150 ml. of petrol.
O Sudden acceleration :Ten sudden accelerations wastes 100 ml. of petrol.

Stop brake riding

Brake riding pushes the brake shoes / pads to come in contact with revolving drum / disc. To overcome the resulting frictional load, engine burns additional petrol.

Result: Low mileage, loss of power, faster wear of brake shoes / pads and drum / disc.

Never clutch ride

Clutch riding slips the clutch & engine drive does not get totally transferred to the rear wheel. Besides low mileage, clutch riding ends up with burnt friction plates of clutch, loss of power and engine overheating.

Avoid frequent braking

O Braking arrests the road speed. Motorcycle momentum is reduced. Additional fuel is burnt for subsequent acceleration.
For better mileage, use front and rear brakes only when absolutely needed. Control vehicle speed with throttle and gear like smart riders always do.

Avoid over loading

○ Over loading tires the engine, wears the parts faster and reduces mileage.

Park your vehicle in shade when not in use

Petrol is highly volatile. It evaporates under normal atmospheric temperature. The evaporation increases with temperature. Prevent this loss by always parking your vehicle under shade.
☐ Too few Kms. running per day allows more time for evaporation affecting the mileage.
