Engine Oil

Engine oil lubricates, cleans, and cools critical parts of the engine. The oil's additives also help to suspend dirt, where it can be drained at the next oil change.

Engine Oil

Checking Engine oil level is the most important under-hood check you can do. An engine cannot run without oil even for a minute without serious engine damage or total destruction! To check the oil level, make sure that the engine is turned off, then find the engine oil dipstick and remove it. With a paper towel or rag, wipe off the end of the stick and notice the markings on it. You will usually see a mark for "Full" and another mark for "Add." Check your owners manual to be sure. Push the stick back into the tube until it seats then immediately pull it out to see the oil level. You should not add oil unless the level is below the "Add" mark and NEVER add oil to bring the level above the "Full" mark. Your main concern with this check is that oil consumption is not rapidly increasing. If it is, take your car to a repair shop as soon as possible and have it checked out. It is acceptable for the oil to be dark as long as you change it at the recommended intervals. However, it should never be foamy and should never have a strong gasoline smell. If either of these conditions exist, have it checked out soon.

Engine Oil

Periodic oil and filter changes keep your engine clean on the inside. Motor oil can become contaminated by dust, metallic shavings, condensation, and even antifreeze. Additives break down over time and can also act as contaminants. The best advice is to follow the guidelines provided in the vehicle owner's manual, but every 3,000 miles or 3 months is a good rule of thumb for oil and filter changes. Many car manufacturers today are recommending extended oil drain intervals for some drivers. However, if you regularly make short trips in your car, drive in stop-and-go traffic, idle for extended periods, drive in dusty or dirty air conditions, tow a trailer or live in a cold-weather region, it's best to stick with a 3,000- mile/3-month regimen.

If you change your own oil, be sure to properly dispose of all waste. A single quart of used engine oil has the capacity to pollute 250,000 gallons of ground water. Never pour used oil down the drain or into the ground. Not only is it illegal, it's also harmful to the environment. Used engine oil is converted for new uses, such as industrial fuel or lubricants. Put used oil into original oil containers or other clean, plastic closed containers, with the contents clearly labeled on the outside and bring the used to oil to a facility that accepts used engine oil.
