How To Change Motor Oil:

How to Change Your Car's Motor Oil

by Stephen Bucaro

First, let's answer the question; Why should you change your own oil? Because you can save time and money. You don't have to wait in line at the service garage or quick oil change shop. For ten bucks you can get the best oil and a brand new oil filter. And, it's so easy to do that you could train a monkey to do it.

Changing your cars motor oil is a very simple three-step process: 1. Drain the old oil. 2. Replace the oil filter. 3. Add the new oil. But before we go through the steps, lets answer a few basic questions.

When should I change my oil?

Look in your cars owners manual. Most auto manufacturers recommend changing the motor oil every 6,000 miles for normal service, or every 3,000 miles for severe service. I change my oil every 6,000 miles, and my engines run like new when I trade my vehicles in with well over 100,000 miles on them. One thing that I do is change a new cars oil after the first 300 mile break-in period. Then, after that, I change the oil every 6,000 miles.

What kind of oil should I use?

You are not going to save money by using an off-brand oil because your engine will wear out sooner. Use oil that meets the American Pertroleum Institute (API) classification SL. I use Valvoline, Quaker State, Pennzoil, or Havoline brand oil. These quality oils contain additives that make them work better and longer.

If you are changing your oil just before winter, use SAE 10W30 weight oil. This number means the oil will have a thin 10 weight viscosity when the engine is cold, helping the engine to start easier, and then the oil will thicken to 30 weight viscosity when the engine warms up, protecting the engine better. If you are changing oil just before summer, use SAE 10W40 weight oil. The extra 40 weight viscosity will protect your engine better when it's hot.

What's the First Step?

First let your engine cool off. Modern engines run at close to 300 degrees (F) and hot oil will definitely give you a severe burn. You shouldn't have to jack your car up unless you have some kind of ground hugging sports car or low rider. Almost all cars have enough space underneath to reach under and change the engine oil.

Step 1: Drain the old oil.

Locate the oil drain plug and place a pan under it to catch the oil. With a box wrench, remove the oil plug.

Note for newbies: To remove the drain plug, turn it counter-clockwise.

- If you have a GM dual-overhead-cam EcoTec engine you may have a difficult time locating the drain plug on all that aluminum.

When the oil stops draining, reinstall the drain plug.

Note for newbies: To replace the drain plug turn it clockwise. Start the plug with your fingers. If it seems even slightly hard to turn, back it out! You are crossing the threads.

Step 2. Replace the oil filter.

Move your oil catch pan under the oil filter. Using an oil filter wrench to get it started, remove the oil filter. (newbies: counter-clockwise, and you will get some oil on your hand.)

-A strap type oil filter wrench is the best kind to use. A socket type oil filter tool is used with a ratchet just like a regular socket. The problem with the socket type is that it tends to get stuck on the filter. Use the socket type tool if you don't have enough clearance around the oil filter to use the strap type.

With your finger put a thin coat of oil on the new filter's gasket to make it seal better.

*! Now pay attention - here's were you can screw up royal!

With your hand, install the new oil filter. If it seems even slightly hard to turn, back it out! You are crossing the threads. Most filters have an instruction printed on them to give the filter one more turn after the gasket has made contact.

Here's what I recommend: screw the filter on until its "hand tight". Then use the oil filter wrench to snug it up another 1/8 to 1/4 turn. This is critical!
