How to Change Oil in a Car

How to Change Oil in a Car

1. Warm Engine and Park on Level Surface
After you have collected all of the tools and supplies you need to prepare your vehicle.

How to change oil: The first thing you should do is start the car and let it run for one to two minutes (longer if the weather is cool). This will warm the oil and the engine and that will allow more of the oil to drain out. Just don't run the engine too long - You don't want to be scalded trying to oil out of the engine.

After the engine is warm, find a flat surface to park on (preferably a driveway or pavement). Then put the car in park and block the tires. It is important to block both the front side and back side of the tires with wheel chocks (a wooden block will do too - see image below) to make sure that the vehicle does not roll when jacking it up.

2. Jack up Car and Insert Jack Stands
Check your auto repair manual to find the best location for the floor jack and the jack stands. Most cars and trucks have markings (usually arrows) on the sides under the body of the vehicle that show where to place jacks and jack stands.

I prefer to jack the vehicle from the center under the engine, then place the jack stands on the sides. The photo below shows where I jack the vehicle up most of the time:

The next two photos show some common locations for jacking and jack stands. After the jack stands are in place jack the vehicle up enough so that you can fit underneath to loosen the drain plug and replace the oil filter.

After the jack stands are placed I lower the vehicle onto the jack stands. This creates much more stability than with a jack alone. Sometimes I leave the jack under the engine too, just as a safeguard against the jackstands failing.

3. Locate Oil Drain Plug and Oil Filter
How to change oil: Next you will need to locate the oil filter and oil drain plug. You should be able to find the locations in your owner's manual.

The oil filter is usually located in the hardest possible place to reach...just kidding! It is usually on the side of the engine about halfway up. Sometimes it takes a lot of looking to find it. You might need to look from the top of the engine to see it.

The oil drain plug is located on the bottom of the engine at the lowest point of the oil pan. Sometimes you will need to take off a skid plate or some type of plastic underbelly to get to both the oil filter and the oil pan drain plug. This picture will show you what you are looking for.

4. Remove Drain Plug and Drain Oil from Car
After you have found the oil filter and drain plug, the next step in this how to change oil guide is to find the right sized socket, then loosen the drain plug with a socket wrench.

The point of loosening the drain plug first is that it is much easier to do without the bulky drain pan in the way. Once it is loose you should put on work gloves to protect your hands, position an oil drain pan under the engine then remove the plug the rest of the way.


Be sure to place the drain pan back further than you think it needs to be because the oil will likely shoot out about four to six inches from the drain hole.

Always be sure to have a good way to store the used engine oil. The best way to do this is to have a dedicated gas can that is made for this purpose. If you use old milk jugs you will have a mess on your hands and in your car when you try to transport the jugs.

When the gas can gets close to being full you can take it to most any auto parts store and they will empty it for free.
