The Landers McLarty Subaru Service Department reminds car owners that getting your oil changed can be the most single important preventative maintenance for your vehicle. The general rule of thumb is to change your car's oil and oil filter every 3 months or every 3,000 miles, whichever comes first. You should consult your owner's manual for the exact manufacturer's specifications for your car, which may differ slightly.

The owner's manual will have "normal" and "severe" recommendations. Severe driving conditions include driving in stop-and-go traffic or excessive idling, making frequent short trips (less than 5 miles per trip), driving in extreme temperatures (over 90 F or below freezing), and towing and hauling. The average driver probably considers his or her driving conditions normal, but the truth is that most of us drive under severe conditions far more often than we realize and should time our oil changes accordingly. However, sticking to the 3-month/3,000-mile rule is considered the minimum drain interval necessary for maximum engine performance.


Most car owners don't realize that getting an oil change dramatically reduces the risk of engine problems as their Subaru gets older, and the time it takes to change your oil is usually somewhere between 20-30 minutes.  Not taking your car in for a regular oil change may result in:

1. Oil Stress

Because of high operating temperatures, oil experiences a thermal breakdown. The thermal breakdown wears on the oils additives and lubrication. When the lubrication wears down, parts of the engine may begin to rub against each other causing dysfunction and a shorter life span for your engine.

2. Combustion Gunk

Combustion gunk can do major damage to your engine and makes your car run less efficiently. Gunk occurs when there are corrosive byproducts that build up in your oil over time. Gunk left for a long period of time can cause your engine to overheat, leaving you with a major bill.

3. Corrosion

Along with sludge, that is naturally produced by combustion, your oil can also accumulate debris such as water, dirt and dust. This debris can actually corrode the inside of your engine. By keeping fresh oil, you clean out any oil with saturated debris.

4. Clogged Filters

When you have your oil changed you will also get a new filter. The filter works to keep the sludge from reaching your engine. But if the filter is not changed regularly, it too becomes clogged with particles from old oil, dirt or combustion sludge and decreases the amount of good oil that gets to your engine. A decreased amount of oil to your engine could kill it.

5. Leaks

Over time some cars can leak gasoline or coolant into the oil. While this is rare, you wouldn't be able to tell if this is occurring unless you had an oil change. These leaks can seriously contaminate your oil, which will, overtime, damage your engine.
