How to Change Engine Oil
Time: 2017-10-23
Changing engine oil is necessary to keep your engine running without internal damage. Changing your own oil ensures the quality of the oil installed back into the engine.
When mileage has been put on an engine the oil inside becomes dirty due to carbon blow by from the pistons and small metal particles which occur because of rotating and moving internal metal parts. Dirty engine oil will wear engine out because of the added friction the internal parts will endure while the oil loses its viscosity.
An oil filter is used to remove impurities in the oil to help the oil stay clean longer. When an oil filter is left on an engine too long it will plug and bypass allowing the dirty oil to circulate inside the engine causing accelerated wear which will be indicated by excessive engine noise.
There are two different kinds of oil change: conventional and synthetic which vary greatly in price. This is due to the cost difference between conventional oil and synthetic oil.
If you were to take your car into the shop to have the oil changed you can expect to pay between $35.00 and $45.00 for a conventional oil change whereas synthetic oil changes will run between $75.00 and $85.00. If you are doing the job yourself you can get Mobil1 (best synthetic oil) for about $25.00 per 5 quarts and a factory oil filter for between $5.00 and $10.00. Conventional oil will run about $11.00 per 5 quarts.
Oil change duration will vary depending on which type oil your engine has in it. Most manufactures require synthetic motor oil which will last between 6 and 7 thousand miles whereas conventional engine oil will last between 3 and 4 thousand miles while still offering the engine a satisfactory level of protection.
If you do not know the last time the motor oil was changed remove the dipstick and inspect the color of the oil. If it is dark brown or black it is time to do an oil change.
Choosing the right oil will mean the difference of having an engine last for many miles or experiencing frequent and costly breakdowns. There are many weights and qualities of motor oil which must be considered when choosing the right oil for your car.
Oil is graded by quality which will be rated as (API), SJ, SL, SM, SN, CH-4, CI-4, CI-4 PLUS and CJ-4. The oil needed for your engine will be mentioned on the oil fill cap on the valve cover in yellow or orange lettering. If you drive your car in cold weather you will want lighter weight oils and when in hot weather a heavier weight. In general you should stay with name brand oils and you will be okay.
