When to change Engine Oil and Filter When to change Engine Oil and Filter, after 5000 Km / 6 Months interval or after 15000 km / 1.5 Years interval. As most of the Beat Owners are now approaching 5000 km / 6 months mark a question is arising whether it is necessary to change the engine oil and filter.
According to me it is a must to change engine oil and filter after 5000 km / 6 months for most of the Beats running in India.
Why?
Because engine oil plays very important role in an engine, like
1. It provides lubrication that overpowers the frictional resistance to reduce wear and tear, to give engine a longer life,
2. It seals the clearances within the engine and gives engine maximum power,
3. It cools and soothes the engine under extreme conditions of heat,
4. It cleans the engine to give sludge free life, and
5. It prevents engine’s metallic parts from corrosion.
We cannot judge these properties of engine oil by its colour or by touch and feel. Whatever we visually observe are the properties at atmospheric temperature, whereas it is a totally different story inside the engine where the piston-ring temperature may reach 230 degree C at full throttle. That is why engine oil must have right viscosity. I have learnt from the literature that most of the maufacturers, including Maruti Suzuki, recommend selection of the proper grade or viscosity of oil according to the average atmospheric temperatures in one’s driving area.
Here is the Maruti Suzuki Ltd.’s chart for appropriate oil viscosity selection.
It can be seen from the above chart that Maruti Suzuki recommends use of 10W-30 Oil in those areas where minimum temperature goes below -10 degree C and maximum temperature goes up to 32 degree C and use of higher rating 10W-40 or 10W-50 Oils in those areas where maximum temperature goes beyond 42 degree C. So it can be concluded that 5W-30 Engine oil is best suited for the regions having a minimum temperature less than -10 degree C and a maximum temperature up to 32 degree C, most of the times in a year. The viscosity grade of Beat’s Engine Oil is 5W-30 and according to Owner’s Manual it is required to be changed at 15000 km / 1.5 years interval for the vehicles with normal annual mileage. But Owner’s Manual also recommends oil and filter change at 5000 km / 6 months interval if vehicle is operated under extreme conditions. Extreme operating conditions are described in the Page no. 137, in which “driving in heavy city traffic where the outside temperature regularly reach 32 degree C or higher is considered as one of the extreme operating conditions”. Under extreme operating condition oil start loosing above mentioned properties earlier than the recommended interval. Therefore I am of the opinion that "in regions where maximum temperature remains below 32 degree C for most of the times in a year oil and filter can be changed after 15000 km / 1.5 years and in regions where maximum temperature remains above 32 degree C for most of the times in a year ( as in most of the parts of India) oil and filter must be changed after 5000 km / 6 months. |
