Maintenance Tips: Engine Oil

Great maintenance on engine oil equals excellent performance. Check out these five excellent tips!

1. Check engine oil at every other fill-up

For an accurate reading, follow this procedure:

• Run or drive your car for about 15 minutes to warm the oil; then park the car in a level place.Turn off the engine and wait 15 minutes to allow the oil in the engine to drain back to the oil pan.
• Remove the dipstick and wipe it clean with a paper towel or rag. Reinsert the dipstick, being sure to push it in all the way, then pull it out again to check the oil level. It should be somewhere between the hash marks on the dipstick.
• Add the type and amount of oil as specified in your owner’s manual, if necessary.

2. Change oil frequently
Your dad knew that frequent oil changes were key to keeping his Buick on the road another year. And while owner’s manuals for today’s cars recommend increasing long intervals between oil changes, the fact remains — frequent changes flush abrasive dirt and metal particles out of the engine, prolonging its life. Most owner’s manuals recommend a more frequent interval for “severe conditions.” To maximize the life of your engine, follow the severe intervals recommendations, especially if drive regularly in stop-and-go traffic.

3. Avoid overfilling your crankcase with oil

Don’t overfill your engine crankcase with oil. If you do, the oil can rise into the crankshaft, where air bubbles will get churned into the oil.Your oil pump can’t do a good job of circulating oil with air bubbles. The result can be overheating and stress on engine components. Overfilling can also foul your sparkplugs. In fact, overfilling is a bad idea with all automotive fluids.

4. Wipe oil pan plug clean
If you do your own oil changes, clean the drain plug and washer with rags before reinstalling your oil pan. Some plugs are magnetized to trap metal particles.

5. Don’t forget the filters
There are several filters (the main ones are oil, fuel, transmission, and air) important to preserving your car engine, and they should be changed according to the schedule in your owner’s manual or as follows:

• Change the oil filter at least at every other oil change — every change is even better because the old filter contains nearly a quart of dirty oil that will remain with the new, clean oil. If you change your oil yourself, wipe the filter threads with an anti-seize lubricant, available at auto supply stores.
• Check the air filter every two months and replace it when dirty or as part of a tune-up. Air filters are generally easier to get to than oil filters.You find them under the big metal lid in a carbureted engine or in a rectangular box in a fuelinjected engine — check your owner’s manual for the exact location. Extend the life of air filters by blowing them clean with compressed air.
• Despite claims by makers and dealers that some newer fuel filters never need changing, it’s smart to have it done once a year. A clogged fuel filter will cause poor engine performance (hesitation and starting difficulties) and is an early warning that there may be corrosion in your gas tank.
• Change your transmission fluid filter after the first 5,000 miles (8,000 km) of driving and every 25,000 miles (40,000 km) or two year thereafter.
