Updated: September 24, 2023

Regular change of the motor oil is pivotal for the optimal operation of the Toyota Tundra’s engine. Oil is responsible for the lubrication of all motor elements, along with cooling and providing stable work for the engine.

Without the oil, the engine will run no longer than five minutes. Then it`ll be jammed and out of order. Motor oil performs an important function, but unfortunately, after a while, it loses its properties.

To prevent oil from harming the engine, one has to replace it from time to time.

Good news, the oil change procedure is quite straightforward and requires only a basic understanding of the Toyota Tundra`s structure. At any service station, your engine oil will be changed faster than you can say 'Hammond crashed another car!'

However, if you're looking to save a few quid or you`re an enthusiast who likes to get your hands dirty, keep reading this article till the end to know how to change the motor oil in your Toyota Tundra.

Key Takeaways:

• Regular motor oil changes are vital for the proper operation of the Toyota Tundra’s engine.
• The recommended oil change interval for the Toyota Tundra ranges between 5,000 to 12,000 miles, depending on the type of oil.
• Prolonged usage of old engine oil can circulate harmful elements in the system, leading to engine damage.
• When changing the oil, it's essential to select the proper oil, replace filters, and properly dispose of used motor oil at specialized centers.

How often should you change the oil in Toyota Tundra?

In trucks like the Tundra, manufacturers advise changing the engine oil every 6,000-10,000 miles, depending on usage and the oil type.

Regardless of the distance travelled by the truck, the oil must be changed at least once a year, even if the Toyota Tundra has not been used at all.

Also, the answer to the question of how often you need to change the oil in the Toyota Tundra can be found in the service manuals for each model. The frequency of changing the oil in the engine directly depends on the intensity of use of the Toyota Tundra.

We provide you with the general duration of the motor oil change.

Average Toyota Tundra oil replacement intervals:

• Conventional oil - change interval - 5-7 thousand miles, or once a year, whichever happens more often;
• Synthetic lubricant - Depending on its structure, this lubricant can last longer. Semi-synthetics can be changed once every 8-10 thousand miles, and full synthetics can be changed once every 12 thousand miles. However, keep an eye on the operation of your engine - if you notice any changes or it starts to run unevenly - it may be time to change the oil;
• Alongside the lubricant, we recommend replacing all filters. The replacement of the oil filter must be carried out together with the replacement of the lubricant, while the air and fuel filters are optional (however, we advise you to change them anyway).

Why is it important to change the engine oil in Toyota Tundra?

When the engine is running, the oil is in contact with all its elements: it lubricates them, and, accordingly, collects everything that may be there. For example, soot, metal shavings, and carbon deposits - everything you have on the pistons - will also be in the oil.

If you ignore the oil change for a long time, then all these elements will continue to "circulate" through the system, destroying the engine from the inside.

In addition, at constantly high temperatures, low-quality lubricant can lose its properties and no longer perform its work properly.

As a result, the oil will be more like a cuppa in consistency, and your engine will be poorly lubricated, which can lead to burrs, overheating, and wedging.

How to choose the proper oil for Toyota Tundra?

A lot depends on the choice of oil. At first glance, it may seem that there’s no significant difference between the lubricants, but this is far from the truth. The oil differs in its characteristics and can affect the operation of the engine both positively and negatively.

Here are the main parameters that you should pay attention to when choosing oil for your Tundra model.

The price. Choose an oil that fits your budget, but don’t go too cheap. Counterfeits are possible, and you surely don’t want some unknown liquid running in your engine. Remember, a miser pays twice, so don’t skimp on oil:

Manufacturer. The more well-known the manufacturer, the smaller your chances of coming across a fake. Buy oil only from certified sellers;

Viscosity. This is the most important factor. Viscosity measures the oil's resistance to flow. Viscosity is indicated by such numbers as 5W-30, 10W-40, etc.

Here, the number before the "W" indicates the viscosity of the oil at low temperatures (W stands for Winter), while the number after the hyphen indicates the viscosity at 100°C. It is very important to choose a viscosity that corresponds to the technical characteristics of your Toyota Tundra and the climate in your region.

API Classification. The American Petroleum Institute (API) categorizes oils based on their performance characteristics and the type of engine they’re intended for, like petrol or diesel engines.

These classifications are frequently displayed on the oil can, labelled as “SN”, “SM”, “SL” for petrol engines, or “CK-4”, “CJ-4”, “CI-4” for diesel engines;

Additives. Motor oils might include additives serving various functions, for instance:

• Detergent additives: They ensure the engine stays clean;
• Dispersants: They stop sludge from forming;
• Antioxidants: They combat oil oxidation;
• Anti-wear agents: They shield engine components;
• Corrosion inhibitors: They deter corrosion;
• Friction modifiers: They enhance fuel efficiency.

Type of oil: Oils can be mineral, synthetic, or a blend of the two.

• Mineral oils: They are procured directly from crude oil through refining processes;
• Synthetic oils: They are concocted using chemical processes that yield superior performance, especially under extreme temperatures.

Time required: 30 minutes

Level of difficulty: 2/5

People needed: 1-2

Essential Gear: 

• A compilation of wrenches or sockets;
• Cleaning Rag(s);
• A tool for unfastening the filter or a belt;

Preparation Setup

Apparel - is the first thing to consider before embarking on any task. Don something you won’t mind getting a bit grubby in!

During the process, there's a chance you might get splattered with oil. This kind of stain is notoriously tough to get out, so be cautious and wear something disposable.

Ponder the location where you’ll be changing the oil. You need access to the underbelly of the Tundra; there must be ample space for you to operate freely.

Here are several alternatives you might contemplate:

• Drive the Toyota Tundra onto a ramp or into a pit in the garage;
• Elevate your vehicle on a lift, jack it up securely;
• Ensure that the Toyota Tundra is stable and won’t topple. Safety first!;
• Avoid changing the oil immediately post a lengthy journey. If the engine is heated to operational temperature, the lubricant will be scalding. To prevent any injuries during the swap, let the Toyota Tundra cool down for a minimum of 10–15 minutes.

Locate and Unscrew the Oil Cap on the Engine

Loosen the oil filler cap. Typically, it’s marked with an oil can symbol and the word “oil” inscribed on it. Position the oil cap on a clean rag, and if necessary, wipe away any residue of oil and dirt.

Identify the Oil Drain Plug

Position yourself under the Toyota Tundra in any manner convenient for you. Spot the plug on the engine; it’s designed like a nut and is situated on the engine tray.

Now, set a container beneath this plug. Ensure this container has adequate capacity to accommodate all the waste liquid. Avoid using an undersized container or a bottle with a narrow opening.

Remember, all the oil should be contained within, not spill out, and should be easy to extract later. A deep basin or bucket would be an optimal choice.

Unscrewing the Oil Plug – The Start of Something Exciting!

Alright, first things first, grab the right key for the plug, slot it on, and let’s get unscrewing! Do it gently, wouldn’t want any nasty surprises in the future. If it’s playing hard to get, an impact wrench could be your best mate here.

Be ready, as the moment you unscrew that plug, the oil is going to make a break for it. Get that container in place and try not to wear the oil, yeah?

Patience is key! Let every drop of oil drain out. Got the filler cap off? Splendid! It won’t take more than a jiffy. Keep a keen eye on the draining oil – any shavings, debris, any unwanted bits?

If you find any, might be a call-to-arms for a mechanic! Keep it tidy, keep it safe!

Getting the Oil Plug Back in Action!

Before securing the plug back, give it and its seat a good wipe. A bit of degreaser or WD-40 should do the trick. You wouldn’t want it sticking around for the wrong reasons!

Get it tightened just right. Consult your Tundra’s manual for the torque specifics! Don’t go too loose or too tight!

Time to Unleash the Oil Filter!

Off with the old oil filter! Located on the engine block’s side, a good counterclockwise twist should do the job. If it’s being stubborn, a leather belt might just be the charm! If all else fails, there’s always a special tool for the job!

Remember, there’s still some oil in there, ready to escape the moment you unscrew it. Be prepared!
