Preventative Oil Changes Protect Your Car’s Engine

The engine in your vehicle is the power source. But it can’t work without the oil to make all the parts work together. And the best way to keep an engine running at peak performance is through a regular oil change schedule. 

Engine oil does all of the following to prevent engine wear:

Cools the Engine

A working engine generates heat simply by running. The oil put into an engine absorbs this heat. It then moves it to other places in the system so it doesn’t build up to dangerous levels. The oil itself accomplishes about 40 percent of the necessary cooling of the engine in this way.

Prevents Corrosion

All metal machinery is prone to rust and corrosion. Engines are no different, so motor oil is used to keep the engine as clean and corrosion-free as possible. 

Lubricates

Engine oil is a combination of petroleum with additives infused. This combination deposits a protective layer over all the moving engine parts to reduce friction and excessive heat.

Cleans

Keeping an engine clean and in good working order is a job for both the oil and the oil filter. The contaminants that get into the engine are absorbed by the oil. The oil flows through the system, and those contaminants are blocked by the oil filter so they don’t go back into the engine. This is why the oil filter must be changed regularly, too.

Even under the best conditions, though, engine oil does break down. It becomes ineffective over time depending on the kind of oil there is in the engine. It also depends on how well the engine is being maintained. 

Continuous protection is a result of the oil and the oil filter being changed regularly. If not, the engine can overheat, pistons will stick, debris will clog the system, and the engine will eventually fail.

Oil Change Schedule

Most auto industry experts recommend an oil change every 3,000 miles (or three months, whichever comes first). It’s a safe standard to follow, so ask our San Marcos auto shop service staff to add this to your preventative maintenance visits.

Oil change frequency also depends on:

  • The recommendations in your owner’s manual
  • The age of your car
  • Your driving needs (towing and hauling)
  • Hot or cold climate
  • Type of oil being used
  • Your driving habits (frequent short or long trips)

Many new cars are being manufactured to require fewer oil changes at longer intervals. Discuss this with one of our oil-change specialists if you have questions. 

Benefits of Synthetic Oil

Reliable Automotive in San Marcos uses only the best synthetic oil available. This ensures you are getting the most from your oil changes. 

Synthetic oil is lab created and uses a highly controlled process according to stringent standards. It contains only the best additives and elements of oil. For this reason, synthetic oil provides the highest level of engine protection available. The result is fewer oil changes, usually between 5,000 to 7,500 miles.

Watch For These Warning Signs That You May Need an Oil Change

Owner neglect is one of the top reasons for car problems. You can prevent many major car repairs by checking the oil in your car between regular oil changes. Make it a habit about once a month, and look for the following:

  • A low oil level when checking the oil dipstick
  • The “Check Engine” or “Oil Change Required” light illuminated on dashboard
  • Overly thick, dark, and/or milky oil that comes out in globs
  • Unusual pinging, knocking, or ticking engine noises while the vehicle is running
  • Blue exhaust smoke coming from the tailpipe while the vehicle is running
  • Strong burning oil odor inside the vehicle

If the oil level is low, you can top it off as a temporary measure. Make sure to use the same oil as what is already in the car. Then take the car to Reliable Automotive in San Marcos to find out if there is a leak somewhere in the system.
