Buyers love the Tundra for its versatility; the 2014 model year offered buyers the choice of a 270-hp 4.0L V6, a 310-hp 4.6L V8, or a muscular 381-hp 5.7L V8. The V8s require more oil than the V6, so take a look in your owner’s manual or under the hood to make sure.

Powertrain	Available trims	Engine oil capacity
4.0L V6	SR	6.4 quarts with filter, 5.9 quarts without
4.6L V8	SR5	7.9 quarts with filter, 7.5 quarts without
5.7L V8	SR, SR5 , Limited , Platinum , 1794 Edition

Don't confuse engine displacement with oil tank capacity. The first measurement measured represents the size of the engine in liters. The second represents the volume of the car's oil tank in quarts. If you pour 4.0L of oil into a 2014 Toyota Tundra’s oil tank, you won't be giving it everything it needs.

What kind of oil does a 2014 Toyota Tundra need?

The official

2014 Toyota Tundra’s owner’s manual

recommends using SAE 0W-20 Toyota Genuine Motor Oil.

Toyota Genuine Motor Oil is supposedly "formulated with a special additive package that helps protect Toyota metal and gasket surfaces from corrosion". It’s also manufactured and sold by Toyota and tends to be on the expensive side. For a generic option, opt for ILSAC GF-5 multigrade engine oil.

“SAE 0W-20”? “ILSAC GF-5”? If these terms look like gobbledegook to you, you’re not alone. Here’s a full breakdown:

"SAE" uses the rating system set by the Society of Automotive Engineers to indicate the oil’s viscosity. The oil must retain the right viscosity, or thickness, at your truck's lowest and highest operating temperatures in order to work.

“0W” indicates the lowest temperature range at which the oil still performs its best. “W” stands for “winter” and “0” indicates a maximum cold operating temperature of -40°F. It’s the “highest” cold rating in the biz.

“20” indicates the highest temperature range at which the oil still performs its best. SAE 20 oil is commonly used in North America where temperatures don’t exceed 20°C (86°F). However, if you shipped your Tundra to Nigeria, you’d probably have to switch to SAE 40 oil, which is good up to 104°F!

Engine oil labeled “ILSAC GF-5” indicates that the oil has been graded and approved by The International Lubricant Specification Advisory Committee (ILSAC). “GF-5” performs better than “GF-4”. Since 2011, it's been the standard grade of engine oil for just about every passenger car in North America because

it improves fuel economy and reduces emissions

How often to change the oil on a 2014 Toyota Tundra

According to the

2014 Tundra maintenance guide

, you should perform the first oil change at 5,000 miles/six months and every subsequent change at 10,000 miles/12 months.

Fortunately, the 2014 Tundra can remind you when it's time to change the oil. An orange

maintenance required light

will illuminate in the upper left corner of your instrument panel every 5,000 miles or so. However, you might need to make a change sooner (or later) depending on how and where you use your vehicle—the only way to be sure is to regularly

check your engine oil

If you notice any of these signs, it’s time for an immediate change:

Motor oil that is dirty, dark brown, or black

Oil that is coarse or gritty

Unusual engine noises

The smell of oil, smoke, or burning

Performance changes in your car

The

cost of a Toyota oil change

ranges from $40 to $120. If you’d rather save your money, we explain how to do it yourself in the following section.

How to change your oil and oil filter

Changing the oil on a 2014 Toyota Tundra

requires at least 6.4 quarts of SAE 0W-20 ILSAC GF-5 engine oil, a new oil filter, and 45 minutes of your time.

Here’s your shopping list: a drain pan, a funnel, a 3/8” ratchet, a 3/8” extension, a 14mm socket wrench, and a

Toyota Oil Filter wrench tool

that matches your engine size. We also recommend you grab some shop rags, rubber gloves, and an old set of clothes because oil stains easily. Once you’ve got everything together, here’s what to do:

Start the engine and let it run for five minutes. Turn off the truck and pop the hood.

Remove the skid plates blocking the oil filter housing cap. You’ll need a 12mm and 10mm socket to do so.

Position the drain pan and remove the oil drain bolt with the ratchet and 14mm socket. Allow the oil to drain completely.

Remove the oil filter housing cap with the ratchet, extension, and filter wrench tool. Clean the oil filter housing cap, replace the old filter, and replace the oil filter housing cap in the engine block. Replace the oil drain bolt.

Remove the oil fill cap and fill the oil tank using the funnel. Replace the cap once you’re done.

Run the engine for a few minutes and check for leaks underneath the truck. Replace the skid plates once you're done and discard any oil, old filters, and oil-soaked rags. Since engine oil is considered a hazardous substance, you should always check with your local government for proper disposal procedures.

Your Tundra’s “MAINT REQ’D” light should be switched off by now. If it’s not, and you want to make sure it’s properly counting down the miles, you’ll need to

clear the maintenance required light

. Here’s how:

Insert your key into the ignition and turn it ON without starting the truck. Press the odometer knob (or the “Display Change” or “Trip” button) on the dashboard until the instrument panel displays “Trip A”.

Turn the ignition to OFF.

Press and continue to hold the odometer knob while switching the ignition back to ON. Again, don’t start the truck.

When the trip meter returns to zero, release the odometer knob.

At this point, any “MAINT REQ’D” or

oil pressure lights

should be long gone. Congratulations! You just performed one of the most important tasks in a

regular car maintenance schedule

. Everyone knows that

Toyotas last forever

—keep it up and your Tundra could be the one to make it to the 200,000-mile finish line.
