The engine in the Toyota Tundra is a 4L V6. Toyota also made a 4.7L V8 engine available in their Tundra pickups.
The engines of every Toyota Tundra are adjusted for 87 octane “regular fuel.” Instead than measuring performance, the octane rating assesses the fuel’s resistance to pre-ignition. Low octane fuel is not advised, and premium fuel with a higher octane level won’t significantly improve performance.
The Toyota Tundra is available with a 4.0-liter V6 with 270 horsepower, a 4.6-liter V8 with 310 horsepower, and a 5.7-liter V8 with 381 horsepower. While the V6 has a five-speed automatic transmission, the V8s have a six-speed.
Four-wheel drive (4WD) is only available on the V8 models and is not standard. Instead than measuring performance, the octane rating assesses the fuel’s resistance to pre-ignition. So normal gasoline with an octane value of 87 is advised for the car.
Two engines are available for the 2018 Tundra: one is a 4.6-liter V-8 that produces 310 horsepower and 327 pound-feet of torque, and the other is a 5.7-liter V-8 that produces 381 horsepower and 401 pound-feet of torque.
A six-speed automatic transmission is the only available transmission.
The car is advised to run on ordinary gasoline with an octane rating of 87.
All models of the most recent Tundra are powered by a 5.7-liter V-8 engine that makes 381 HP and 401 lb-ft of torque. It has a six-speed automatic transmission with RWD as the default and 4WD as an option.
The engines of every Toyota Tundra are adjusted for 87 octane “regular fuel.” (The fuel’s resistance to pre-ignition is measured by the octane rating rather than its performance.)
Engine performance and mileage are unaffected by octane levels over the permissible range. Much more important variables that will affect mileage include vehicle load, speed, traffic, and weather. Any variations in power or mileage won’t be noticeable.
In 2022, the next Toyota Tundra is anticipated to include a 5.7-liter V8 similar to the 300-Series Land Cruiser and a twin-turbocharged 3.5-liter V6. Additionally, a diesel version would be made available.

What occurs if you enter 93 rather than 87?
Most of us regularly operate a car or truck that runs on ordinary, unleaded fuel. This makes filling up at the gas station rather straightforward. But occasionally, someone can unintentionally use a different type of gasoline than usual to fill their car.
The majority of today’s cars and trucks are equipped with electronic fuel management systems that can detect the difference between ordinary and premium gas (lower and higher octane) and modify the ignition timing and fuel injection accordingly.
Don’t worry if you mistakenly put a higher octane blend (such 91, 92, or 93) into your tank than the standard 87-octane fuel. Actually, you’re using a different gas blend to fill your car or truck, which means your engine will operate differently as a result. There might be a slight difference in how the car feels and you might see better gas mileage, but that’s about it.
Premium Gas Vehicles
Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.
You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.
Diesel Vehicles
You must be aware of how diesel fuel and unleaded fuel differ from one another and which your car needs.
Inadvertently using unleaded fuel in a diesel-only vehicle will actually reduce the lubrication that diesel provides for the car’s components. As a result, there will be significant damage from the pieces grating against one another.
The damage may not be as severe if you fill your ordinary gas vehicle with diesel, but you won’t travel more than a few miles before the engine starts to splutter, cough, and lose power. You’ll be able to drive the vehicle once more when you replenish the diesel tank and flush out the fuel lines.
Do yourself a favor and refrain from starting your automobile if you have the wrong kind of gas in it and haven’t done so yet. When the incorrect fuel is pulled up into the fuel lines, engine damage results. Call a mechanic instead, and ask them to fix the problem.
Does the Toyota Tundra need premium fuel in 2022?
Without a heart transplant, the 2022 Toyota Tundra’s metamorphosis would not have been complete. The twin-turbocharged 3.5-litre V6 engine, which can produce up to 389 horsepower and 437 pound-feet of torque, has taken the place of the previous V8 engine (apparently just 348 horsepower and 405 pound-feet in SR trim). These numbers are increased to 437 horsepower and 583 pound-feet by a hybrid variation known as the i-Force Max. Unexpectedly, standard 87-octane fuel is advised.
Every model has a 10-speed automatic transmission as standard equipment. The new Tundra can tow between 11,000 and 12,000 pounds, depending on configuration. 1,940 pounds are the payload.
Particularly when combined with the electrified engine, the drive is fairly believable. Fun fact: When you press the accelerator, a synthetic V8 engine sound plays through the speakers, and it’s more enjoyable than you might imagine. The Tundra feels more stable and surefooted because to the greatly improved ride and handling provided by the much more rigid chassis. Meanwhile, comfort levels have greatly increased.
How about fuel efficiency? The ratings for the hybrid version won’t be available until next spring, but converting from U.S. mpg numbers, the gas-only 2022 Tundra obtains a combined 12.4 L/100 km (10.7 L/100 km on the highway, 13.8 L/100 km in the city).
Can 87 and 91 gas be combined?
Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.
What kind of fuel does Toyota advise?
Technical prerequisites
- Use RON 91 gasoline if “Regular” on the domestic Japanese market or RON 91 on the North American market is advised for a particular engine.
- Use RON 95 or 98 gasoline if “Premium” in the domestic Japanese market or RON 95+ in the North American market is advised for a particular engine.
- Use only the gasoline that is listed in the owner’s manual and on the fuel filler flap during the warranty period.
Comparing manuals for comparable models sold in the Japanese, American, and European markets will help you better understand the manufacturer by allowing you to distinguish between ‘environmental’ and marketing concerns and actual technical requirements.
It is so simple to see that although while the majority of Toyota engines, particularly those in the mass market, were initially intended to run on Regular (in Japan) or RON 91 (in the US), the nominal octane number is invariably raised to 95 for use in Europe.
For “sporty” naturally aspirated engines, turbocharged engines, and high-power V6-R6-V8 engines, premium/RON 95 is helpful.
For reinsurance purposes, Premium is occasionally advised for MT models, whereas Regular is sufficient for the same vehicle with AT or CVT.
Each engine series underwent continuous modernization during the production phase, which occasionally resulted in revisions to the acceptable octane number (to higher or lower).
Sometimes the standards at North American market are softer than at JDM, which suggests that such engines have not a critical need for high-octane gasoline, but it will increase performance.
In the past, when there were ignition distributors, fixed valve timing, traditional multi-point injection, and the Otto cycle, a folk rule was established that said, “If compression ratio is below 10, use RON 92, if it is above 10, use 95, and if it is over 11, use 98.” For older, traditional engines from the last century, it was generally accurate.
It’s odd that this stereotype is still in use today. Individual ignition, wide-range variable valve timing, and the Miller cycle were all introduced long ago, so the nominal (geometric) compression ratio now connects with reality differently than it did two decades ago (it should actually be called the “expansion ratio”) Toyota’s new engines, which have compression ratios of 1314 and 10+ for turbo engines, use regular fuel.
Observed that some owners follow the maxim “high octane for high technology” and exhibit an odd respect for D-4. The requirement for high-octane fuel is partly brought on by misleading parallels with German automobiles, but FSI/TSI engines are augmented by turbochargers.
And it would be necessary to reiterate that one of the primary drivers behind the initial implementation of gasoline direct injection (during World War II) was the chance to reduce knocking and increase the compression ratio or boost pressure, respectively to boost power output and use subpar gasoline. Toyota’s D-4 had similar goals in mind when it boosted compression ratio and enhanced efficiency while preserving power. The second benefit is that fine fuel dispersion enhances starting at low temperatures in current engines by promoting better evaporation than standard MFI.
As a result, the sensitivity to fuel quality is not increased but rather decreased by direct injection alone.
By the way, some small-displacement motors (4E-FTE, 8NR-FTS) built for Regular, as well as current, powerful V35A-FTS for American Tundra, are examples of turbo engines where increasing the octane number is the rule rather than an axiom.
2. National highlights
There would be no need for a further discussion if we could only live in a civilized society. Yet sadly… The simple linear problem becomes three-dimensional and dialectically difficult when the second axis of “octane” is added to the “octane” scale in local realities, followed by the addition of the third axis of “geography”.
In the 2000s, it was feasible to declare, “Use RON 91 whenever and wherever possible.” It was actually “cleaner” and “more pure” throughout Mordor, with better consistency in quality from area to area, providing a more constant beginning, and leaving behind less layers of soot and metal oxides. And it is obvious that despite the fact that ’95 sold several times as many copies as was officially produced (and without any import), discussing quality was pointless.
Today, generalizations about all gasoline types must be avoided because the quality of different gasoline types from large refineries is aligned such that any variances appear to be random fluctuations (from plant to plant and even from batch to batch). Small producers and sellers can even produce 91 items of impure quality.
And must realize that when it comes to local “92 or 95,” it is not a matter of cost-savings (a few dollars for a full tank), but rather of gasoline quality, suitability for particular local conditions, and prejudice on the part of people.
However, the relentless and even hostile promotion of high-octane gasolines (98-100+) in a particular segment of the information community justifiably elicits a suspicious response and the customary “cui prodest?”
It is apparent that car owners of various European brand names produce the majority of the information flow on themes related to fuels and lubricants. Even brand-new Toyota engines are the exact antithesis of the modern, high-tech, frequently thermally loaded downsizing turbo engines. Therefore, don’t extrapolate their humbling experience to Japanese and Korean brands, and don’t impose your own recommendations.
Understanding how “Europe” relates to a local reality in general and to Japanese automobiles in particular would be nice. But you’re right to have noticed that Germany was the only European nation to still have a sizable “91” distribution, and between 2007 and 2010, gas stations removed it from the market since “Normalbenzin” demand had fallen. Therefore, it is not unexpected that the owner instructions for European markets do not include RON below 95. (not because it is forbidden, but because there is no such thing).
Do the authors of these “discoveries” really think that someone could locate and study “American” manuals without knowing the distinction between AKI and RON? By the way, Toyota literally writes “Unleaded gasoline (Octane rating 87 [Research Octane Number 91] or higher)” in US manuals.
Since 1986, the JIS K 2202 standard has defined “Regular” as gasoline with a RON above 89 and “Premium” as gasoline with a RON above 96.
The numbers in the table below have been “unified” with global RON values. In our nation, all high-octane gasoline is produced by supplementing low-octane with additives.
The notion that “local refineries can only generate RON 92, which is subsequently combined with additives to produce 95-98” is another outmoded myth.
All of the major refineries have really undergone multiple modernizations, allowing for the mass production of any type of gasoline today by “compounding of the results of catalytic reforming and cracking with various high-octane components.” Methyl tertiary-butyl ether (MTBE) and tertiary amyl methyl ether are referred to as high-octane components (TAME). Although it is evident that the finished product is subpar compared to European or American gasolines (where better technology is employed), it is on a different level from former periods.
To think that all commercial gasoline in the nation is of average grade, however, would be nave. that unidentified “manufacturers” can be stopped by the restriction on organometallic additions (ferrocene, cymantrene). The earlier monomethylaniline (MMA) ban has reduced its effectiveness. There are still sufficient amounts of industries producing and selling straight-run technical gasoline, small illicit refineries are still operating, and there is a significant proposal for truly “nuclear” additions to raise the octane number of any slops by 2030 units. In any case, the likelihood of discovering low-quality fuel at gas stations with well-known brands has significantly decreased.
Fuel evaporability, which is determined by vapor pressure, determines how easy a cold start will be. The standard guideline used to be: best volatility 92, medium volatility 98, and worse volatility 95.
Today, especially if you believe the data sheets at the gas station, which are often jumbled up – value could vary even between batches of the same type from the same plant, so the only thing left to say is whether the gasoline was “good” or “bad” at the time it was detected at a specific gas station. Although the manufacturer’s data sheet specifies low vapor pressure, there is no prospect of a typical cold start with this fuel, even though it is recognized that the paper can withstand anything.
People will find a way to “optimize” and “rationalize” wherever the human factor makes it possible, even when it seems impossible. Applying personal gain, commercial interests, and feudal social relations here will have unanticipated and synergistic results.
Since gasoline is a common fuel, it can experience the most incredible collisions as it travels from the refinery to the tank farm, the farm to the gas station, and the gas station to the car tank. To avoid routine fuel dilution on the road during delivery, top businesses deploy true high-tech against their own tanker drivers. However, the pipeline for the dirt product cannot be changed. While being transported in the same tanks, several fuels are switched out (or even other fluids). With petrol stations that, upon opening, clean the tanks for the first and last time…
Recall the well-known safety measures:
- Refill at only premium brand gas stations (not franchise or jobber).
- Use the highest-quality gasoline available, regardless of the technical requirements of the car, if gasoline quality varies significantly among kinds in a local region.
- Teach the family’s drivers to stay away from no-name gas stations and cheap fuel.
- If forced to refuel, fill just enough to get to a better station.
- Choose the petrol stations where costly automobiles with local license plates are refueled when you’re in an unfamiliar area.
- Choose the station networks with a fleet of road tankers of their own.
- After a lot of rain, avoid refueling.
- Do not refuel while receiving fuel from the tanker at the gas station or right away after.
- Check at least the reported volatility values and the number of light endings in fuel during cold weather.
For us, the worst of the major networks that everyone knows, to demand the usage of particular gas station brands makes no sense. In any event, there is no perfect brand that would apply to the entire nation.
Locally, we can state that the four main oil refineries in the central region, while each has its own advantages and disadvantages, produce goods that are generally of an acceptable to good quality. However, avoid trying to locate the greatest gas in the nation in the nation’s capital.
Can a regular automobile owner go any further? A true advocate for premium gasoline can define the refinery from which each gas station in the network receives its fuel, the current state of production at each facility, and the direction in which the quality pendulum has swung. They always ask for a copy of the data sheets at the gas station, examine them for validity, and analyze and compare the reported octane number, the amounts of sulfur, gum, benzene, aromatic hydrocarbons, esters, induction time, boiling point end, and vapor pressure. They identify the origin refinery based on the fractional content and the type of additives. The primary ingredients and additions can be distinguished based on smell. After every refueling, they linked to the computer and kept an eye on the fuel trim. In multa sapientia multa sit indignatio, it transpires.
