Changing your vehicle's oil regularly will help keep the oil from turning into grimy sludge that will be ineffective in lubricating the working parts of your engine.
The general recommendation is that your oil should be changed for every 3,000 miles you put on your car while driving down the streets of Los Angeles, Long Beach, and Downey. But some auto technicians believe this amount can be extended. Ultimately, it depends on the make and mile of your model of your vehicle. Other factors should be considered as well, such as whether you do a lot of towing and driving in a dusty or sandy area.
You should keep track of how many miles you've driven since your last oil change to determine when you need another one. If your car needs fresh oil, the Check Engine light may come on or your vehicle may make unusual sounds caused by engine components rubbing together.
