About This Quiz

Cars require more than just fuel to keep them moving -- they also require frequent maintenance to keep them in great shape for years to come. The oil change is the one maintenance item virtually every car owner has heard of before. They know their car needs fresh oil and filter every so many miles, but many do not know exactly how to do an oil change. As a car owner, you should be familiar with all aspects of your vehicle, and changing your own oil is a great way to learn more about how it all works. 

Knowing how to do your own oil change can not only save you money in the long run, but it will also build your confidence and show you things about your vehicle you may never have known before. You may also find out you have a knack for this mechanic thing and get the confidence to try other money-saving maintenance or repair processes yourself. But you have to crawl before you walk, so get started with a simple oil change and move up from there. 

Think you have the automotive know-how to do a complete oil change the right way? Take this quiz to find out just how much you know about this basic car service!

What is the right oil for your vehicle?
The weight the manufacturer recommends in the owner's manual
Manufacturers engineer vehicles to operate at peak efficiency using certain oils. Using only the oil weight recommended in the owner's manual will maximize efficiency and the oil's lubricating properties.
It doesn't matter.
Straight 30 weight
10W30 is good in everything.

Other than oil, what supplies will you need for your oil change?
Nothing. Just oil
Oil filter, drain plug gasket (if applicable), rags and an oil-spill clean-up kit
When changing the oil, you will also need an oil filter to eliminate as much of the debris from the old oil as possible. You'll also want rags to wipe up small spills, a drain plug gasket if it is available and an oil-spill clean-up kit in case you have a larger oil spill.
Just the filter
Cat litter

What are the basic tools you will need for your oil change?
Box-wrench set, oil-filter wrench, drain pan, and a 3/8-inch torque wrench
The box wrench set is the best bet for removing the drain plug, and the oil filter wrench is a must have to correctly remove and install the oil filter. The oil also needs to drain somewhere, and the torque wrench ensures you do not overtighten the drain plug.
Vice grips are fine.
Slip-joint pliers
A socket set

Should you change your oil with the engine warm or cold?
Cold is best.
The hotter, the better.
Hot oil flows better, and you will get more of the old oil out if the engine is hot when you drain it. Use special care not to burn yourself.
Barely warm
It doesn't matter.

Before changing the oil, what should you do?
Prep your car by removing the battery.
Replace the air filter.
Remove the oil filler cap and dipstick.
Removing the oil filler cap and dipstick may seem silly, but there is a reason for it. The oil system is sealed, and no air can make it in. If you remove the cap and flip it upside down, the soda glugs out of the bottle and splashes everywhere -- hot oil will do the same thing. Opening the filler hole and dipstick allows air in so the oil drain out smoothly.
Grab a beer -- it's going to be a long afternoon.

When jacking up your vehicle, what should you do secure it and protect yourself?
Throw a used tire under it.
Stuff a rock behind a wheel.
Chock the rear wheels, put jack stands under the vehicle and lower it onto the jack stands.
Chocking the rear wheels prevents the vehicle from rolling back. Lowering the vehicle onto the jack stands eliminates the potential for the jack to hydraulically fail and drop the vehicle on you. You can leave the jack in place and contacting the underside of the vehicle, but leave the weight on the stands.
Wear a chest protector.

Where is the oil drain plug?
On the oil pan under the engine
The oil drain plug is on the oil pan on the bottom of the engine. It is typically at the lowest point of the pan for maximum draining. It looks like a large bolt.
On the side of the engine
There is no drain bolt. You suck the oil out through the dipstick tube.
In the oil filter

How do you remove the oil drain plug and drain the oil?
Turn the plug counterclockwise with a box wrench until it is loose and unscrew it the rest of the way by hand. Let the oil flow from the pan until it comes out just as a slow drip.
The oil takes some time to drain -- plan on waiting about five minutes until it slows to just a drip. You'll never get all the old oil out, so no need to let it drip for hours in hopes of removing as much old oil as possible.
Turn the plug clockwise with a box wrench until it is loose and unscrew it the rest of the way by hand. Let the oil flow from the pan until it comes out just as a slow drip.
Turn the plug clockwise with a box wrench until it is loose and unscrew it the rest of the way by hand. Let the oil flow from the pan for about 10 seconds.
Turn the plug counterclockwise with a box wrench until the oil drips from the pan. Let it continue to drip until it stops.

While the oil is draining, what should you do?
Watch in amazement as the oil flows.
Watch the oil for big clumps.
Clean the drain plug and find the oil filter.
The oil will drain for a while, so keep your hands and mind busy by wiping the drain plug off, installing a new gasket (if applicable) and finding the oil filter under the engine. If possible, you can even loosen the oil filter, but make sure the drain pan is in a position to catch any oil that flows from it.
Crawl out from under the car and relax.

How do you remove a screw-on oil filter?
Using the largest pair of channel-lock pliers you have
Puncturing it with a screwdriver and twisting
With an oil filter wrench designed to remove that style of filter
The auto parts store will have several types of oil filter wrenches available. Some are simple band wrenches that work on multiple types of filters, and others are sized to fit only certain filters. Grab a filter for your car off the shelf and test fit it in a few of these wrenches.
By hand

How do you drain a screw-on oil filter the right way after removing it?
Set it in the grass with the open end down.
Poke a hole in it and set it in your trash can
Wrap it in a bag and toss it in the trash -- no need to drain it.
Set it in the oil drain pan with its open end down.
The oil filter always has about a half quart of oil inside it, and you want to drain as much of it from the filter as possible. Setting it open-side down in the drain pan while completing the oil change will get most of the oil out.

Before installing the new screw-on oil filter, what should you do?
Clean the oil-filter mount on the engine and apply a thin coat of oil to the oil filter O-ring.
Cleaning the oil filter mount on the engine with a cloth will remove any debris and allows you to see if the old O-ring from the old oil filter stuck to the mount. Applying the thin coat of oil allows the new O-ring to slide into place without bunching while you tighten the filter.
Scrape the mount with a razor blade.
Remove the O-ring.
Fill the filter with oil.

How do you install the new screw-on oil filter?
Till it's tight
Just finger-tight
Hand-tighten it, then use the filter wrench to tighten it another quarter turn.
Oil filters do not need much tightening to seal thanks to their large O-rings. Simply hand-tighten the filter and then tighten it another quarter turn with the filter wrench to seat it.
Bang it on with a hammer.

How do you remove a cartridge-style oil filter?
Unscrew the cap with a box wrench and pull the filter upward.
A cartridge filter is contained inside a plastic or metal housing with a screw-on cap. Simply remove this cap with a box wrench and pull the filter out. Some filters click into place, so you may need to pull upward with light force to remove it.
Use slip-joint pliers to unscrew the cap and pull the filter out.
Cut the top off and pull the filter out.
You can skip replacing a cartridge filter.

Advertisement

How do you install a new cartridge-style oil filter?
Just drop it in and go.
Carefully lower the filter in and press downward to seat it, if needed. Remove the old O-ring from the cap and install a new one, of applicable, and finger-tighten the cap onto the filter housing. Torque the cap to the manufacturer's specifications.
The cartridge filter is essentially a screw-on filter without its metal housing, so it still has the same components as a screw-on filter, like an O-ring. The difference is its metal housing just happens to be part of the vehicle.
Put the cap on and set the filter on top of it.
Call a pro to install it.

What should you do before installing the oil drain plug?
Wipe any oil from under the engine and clean the oil pan threads.
Leftover oil on the oil pan can get hot and start smoking. You also want to clean and check the threads on the oil pan, as any debris can cause a poor seal and a leak.
Nothing. Just screw it in.
Sniff the drain plug and check for a gasoline smell.
Tap the pan with a hammer to get out any additional oil.

How do you seat the oil drain plug?
With a power ratchet
Hand-tighten it.
The drain plug is one of the most sensitive pieces in your vehicle. Not only does it hold the most important fluid in place, but it also screws into an easy-to-strip drain pan. Seating the plug by hand-tightening it ensures a good seal.
just start the threads by hand and stop.
Pound it in with a hammer.

How tight should the oil drain plug be?
As tight as you can get it
Finger-tight
To the manufacturer's specifications
The final tightening spec on the drain plug is typically available in the owner's manual or via an internet search. Tightening it to this specification keeps oil from leaking without risk of stripping out the oil pan.
Doesn't matter as long as it's not leaking

Advertisement

How do you lower the vehicle after draining the oil?
Just lower the jack.
Push it off the jack stands.
Lift it off the jack stand with the jack, remove the stands and lower the vehicle slowly to the floor.
Lifting the vehicle off the jack stands, removing the stands and slowly lowering the car to the ground prevents unintended damage. Any other method can cause damage to you or the vehicle.
Put the car in reverse and back it off the jack stands.

Where do you refill the oil?
Through the gas tank
In the oil-filler hole on top of the engine
Every vehicle has a large oil-filler hole on top of its engine. You can refill the oil by pouring it into this hole.
Through the oil dipstick tube
Dumping it into the filter and letting the car run

What is the right way to prevent spilling oil all over your engine while filling it?
Using a large funnel
A large funnel will give you the room you need to safely pour the engine oil without spilling it on the engine. While spilling oil on the engine typically harms nothing, it can cause temporary smoking.
Cupping your hands over the oil-filler hole
Being very careful
Flipping the oil bottle into the filler hole as quickly as possible

How much oil should you put in the engine before starting it?
4 quarts
6 quarts
Until it's full
Add the manufacturer's recommended amount of oil, then check the level on the dipstick. Continue adding until it is at or near the "Full" level on the stick.
Always start by filling the engine with the amount of oil the manufacturer recommends in the owner's manual. Allow the oil to settle for a minute, then check the level on the dipstick. Continue adding oil, if needed, until it reaches or is near the "Full" line on the dipstick.

Advertisement

How do you check the oil before starting the engine?
Allow the oil to settle for a minute, then remove the dipstick, wipe it off and reinsert it.
Checking that the oil is at the "Full" line on the dipstick ensures there is plenty of oil to lubricate the engine. You want to hit the "Full" line because the oil filter will draw in up to a half quart of oil and lower the overall level once you start the engine.
Pull the dipstick out and check the level.
Just add what the manufacturer recommends.
Look in the oil fill hole to see if you can find the oil level.

Your initial oil check shows there is plenty of oil, how do you perform the final oil check? What do you need to do to ensure the oil level is correct?
Start the engine and let it idle for a minute, then shut it off and let it sit for about a minute. Check the oil level on the dipstick.
Allowing the engine to idle flows the engine oil through the filter and the rest of the engine. This ensures you get an accurate reading on the dipstick. Failure to do so could result in a low-oil condition after the oil cycles into the filter.
No need for a secondary check.
Unscrew the oil cap and look inside the engine.
Drive it and see if the oil light turns on.

Advertisement

What is the correct final oil level?
Within the "full" and "Min" range
In the upper one-third of the "Full" and "Min" range
Putting the oil in the upper third of the range ensures there is plenty of oil without the risk of overfilling it. This also compensates for any additional oil that may flow into the filter or remain in the engine at shutdown.
At the "Full" line
Over the "Full" line

Advertisement

Once the final oil level check is complete, what should you do?
Take the vehicle out for a drive.
Allow it to idle for a few minutes and check for any leaks.
Allowing the engine to idle maintains pressure on the fuel system and can expose any leaks. It is best to do this while the vehicle is still in the garage so you can rectify any issues immediately.
Wash your hands.
Pat yourself on the back for a job well done.

While you are under the hood, what else should you check during your oil change?
That the engine is clean
That it's running smoothly
Belts, hoses, air filter and fluids
While you're changing the oil, it is a great time to check other under-hood maintenance items. Things like belts, hoses and fluids are easy to check at this time. Catching a problem now can save you an expensive breakdown later.
Your spark plugs

What should you do with the used engine oil?
Dump it in your yard.
Bury it 6 feet underground.
Recycle it.
Recycling engine oil ensures this contaminated fluid has goes through a safe disposal process. Oftentimes these old oils go into oil burners that provide heat. Dumping it in the ground can cause serious environmental issues.
Throw it in the trash.

What should you do with the used oil filter?
Place it in a bag or box and recycle it along with the oil.
The oil filter is just as contaminated as used oil. You want to dispose of this properly by recycling it.
Throw it in the trash.
Burn it safely in a fire pit.
Hang onto it for safekeeping.

I accidentally mixed conventional and synthetic oil. Now what?
Your engine is toast.
You have to drain it and redo the whole process.
It's OK, as long as it's no 50/50 mix.
Everything is gonna be alright.
There is an old myth that mixing synthetic and conventional oil will kill an engine. Well, it will not. In fact, companies sell premixed synthetic and conventional oil on the shelves -- it's called synthetic blend.

How often should I change my oil?
Every 3,000 miles on the dot
At the manufacturer's recommended intervals
The manufacturers know their cars best, and they know how long their engine can run on the same oil. Don't fall for the quick-lube industry's 3,000-mile myth. Stick to what the manufacturer says, and you are fine.
Every 5,000 miles
At least twice a year

I changed my oil, but my “Change Oil” light is still on. Now what?
You have to redo the oil change.
You must have used the wrong oil.
These systems generally need a manual reset.
Oil-change reminders rarely use any special sensors to actually know when the oil has broken down on a chemical level. Instead they use the miles you drive, environmental conditions and more to gauge when you should change the oil. This means they also need a manual reset. You can find the reset procedure in your owner's manual or through an online search.
You broke a sensor. Take it to the shop.

There were fine metal shavings on my drain plug. Is this a problem?
Yes, your engine is done for.
No, this is normal.
Engines have a lot of moving metal parts, and they rub against each other at high speeds. This can cause mild metal shavings to appear in the oil. This is perfectly normal, so long as there are no large chunks of metal.
No, but you want to take it to a shop for a check-up.
Yes, this is a sign of serious internal engine damage.
