Regular vs premium petrol has been a contentious issue in the Toyota 4runner community, particularly among owners of the 4.7 V8. Your decision could have a significant financial impact given the rising cost of gas. So, should your 4runner be operating on premium fuel?
Whatever your 4runner’s owner’s manual suggests is the best gas to use. The best fuel for your particular model will be premium if it is required. The majority of 4Runners can run on 87 octane safely, but they won’t produce as much power or be as fuel-efficient.

Do Toyota vehicles need premium fuel?
What octane fuel is recommended for my Toyota? My people believe that it is advantageous to fill up their Toyota with high-octane or premium gas (90 octane or higher). The truth is that no Toyota uses a fuel grade greater than 87, with the exception of the Toyota Supra, which has a BMW engine.
Which Toyota models need premium fuel?
Premium gasoline has a higher octane rating than regular fuel and will burn cleaner, quicker, and more efficiently, which can increase power and fuel efficiency. In high-compression and turbocharged engines like the ones featured in the 2021 Toyota GR Supra, high-octane premium fuel performs best. The Toyota GR Supra is the only Toyota car that suggests premium fuel. For more information and recommended fuel, consult your Toyota owner’s manual.
What Are the Differences Between Regular and Premium Fuel?
The octane rating is the primary distinction between regular and premium gasoline. In most states, regular gas is rated at 87 octane. In the majority of states, premium gas has an octane rating of 91 or 93. More detergents and other additives with hydrocarbons that are less susceptible to predetonation in your engine are frequently found in fuel types with higher octane ratings. Your engine may knock or ping, and the cylinders may experience unusual wear as a result of predetonation. Premium fuel reduces the possibility of predetonation and will ignite at the precise moment required for performance optimization.
Do 4Runners use a much of gas?
The 2022 Toyota 4Runner Limited comes in 10 exterior colors, from Lime Rush to Lunar Rock, and boasts a class-leading array of features. These features include, among others, turn signal mirrors, remote anti-theft alarms, and headlamps that detect nightfall.
The 2022 Toyota 4Runner Limited includes the following features as well:
Advanced infotainment system with built-in Android Auto and Apple CarPlay. A WiFi hotspot with a subscription model is another option.
Blind-spot monitoring: Use this extra sensor to keep you and your loved ones safe.
The 4Runner Limited provides lane-departure warnings to keep you focused and out of trouble while driving.
The features go on and on. The 4Runner Limited also features automatic emergency braking, a third row of additional seats, and pre- and post-collision safety systems.
Hows the fuel economy?
The 4Runner Limited has a lot of amazing features. The vehicle only manages a pitiful 19 mpg on the highway and 16 mpg in the city, making it a proven gas guzzler.
While hardly an environmentally friendly car, the V6-powered Jeep Wrangler trumps the 4Runner Limited with highway and city mileage of 24 mpg and 19 mpg, respectively.
Which Toyota 4Runner models have the V6?
All Toyota 4Runner grades share a 4.0L V6 engine with 270 horsepower and a five-speed automated transmission.
There are a number of Toyota 4Runner trims, including the Limited. The TRD Off-road is more athletic and tougher than the SR5, which is the most basic model.
The 4Runner’s acceleration time from a stop to 60 mph is a lethargic 7.3 seconds, so its speed isn’t exactly going to turn heads.
However, SUVs aren’t exactly recognized for their spectacular acceleration as a class. Let’s see how the 4Runner’s 0-60 time compares to that of its rivals:
Is premium fuel actually worthwhile?
Most vehicles accept standard, but few only accept premium. There have been some erroneous purchases made at the pump because it is not quite clear how these two kinds of gasoline differ from one another. Continue reading if you’re unsure about what to put in your car’s gas tank. You could end up saving money.
So, what’s the difference between premium and regular gas?
In most areas, regular gas has an octane rating of 87, whereas premium gas frequently has a higher rating of 91 or 93. Higher octane fuel can withstand greater compression before detonating. In essence, the risk that a detonation occurs at the wrong time decreases with increasing octane grade. This event will occasionally probably not cause any damage to your car. However, if it occurs frequently, it could hasten the performance deterioration of your engine.
For optimum performance and fuel economy, engines with high compression ratios or turbochargers frequently need the high octane gasoline found in premium gas. The majority of vehicles on the road today, however, are designed to run on ordinary gas.
If your car doesn’t require premium, fill up with regular.
Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.
In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.
Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j
If your car requires premium, fill up with premium.
For high compression ratio engines to operate at their intended levels of performance, fuel economy, and emissions, higher octane gasoline is often required. Don’t cut corners if your car requires premium fuel. Your automobile will be less powerful and fuel-efficient even though you might save money on gas. When driving a car with a turbocharged engine, this can significantly alter the performance.
What if premium gas is needed but isn’t readily available? While newer automobiles have sensors that are watched by the engine’s computer to assist prevent knock and, by extension, engine damage, older ones may be subject to engine knock when driving on low octane fuel. As the engine’s computer can alter the ignition timing, your car will probably be alright running on normal occasionally, but we don’t advise doing so frequently.
A modern vehicle’s ECU (Electronic Control Unit) can take differing octane levels into account and adjust when you use a lower grade of fuel than what is advised or required. Your horsepower and MPG are likely to decrease as CO2 emissions increase. Gas may be cheaper, but in this case, you get what you pay for.
If your car only recommends premium, the choice is yours.
The Ford F-150 and Mazda MX-5 Miata are two examples of automobiles for which automakers advise premium fuels but do not mandate it. According to AAA’s research, these vehicles’ performance and fuel efficiency somewhat improved while using premium gas. If you drive a luxury or performance car, premium gas might assist highlight your car’s desired qualities.
However, you can safely run on ordinary if your owner’s handbook specifies “premium fuel suggested.” Commuters trying to get from point A to point b might not notice or care depending on what and how you drive. It all comes down to personal preference in the end. Your rules, your car.
Need some fuel-friendly vehicle choices?
It can be challenging to compare all the vehicles that are now on the market with rising gas prices. Check out these vehicles that use little to no gasoline to make things simpler! Check out these gas-saving suggestions as well.
Do you get higher mileage when you use premium gas?
In luxury and performance automobiles with turbochargers or high-compression engines, premium gas offers a stronger resistance to engine knock, allowing you to reach that horsepower effortlessly. Additionally, premium petrol can improve fuel efficiency, possibly resulting in longer-lasting better gas mileage while lowering pollutants.
Keep in mind that these advantages are only seen in vehicles that actually demand premium fuel, not necessarily in the majority of other vehicles. Note that the definition/label for premium gas can vary from state to state and station to station. Check your owner’s manual to verify what your manufacturer recommends for your individual automobile make and model.
What occurs if you use 93 gas instead of 87 gas?
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.
Is 87 ordinary gasoline?
Any type of gasoline with an octane level of 91 or higher is commonly referred to as premium gasoline, with 91 octane and 93 octane being the most popular brands sold at gas stations in the United States (93 octane gasoline may be called “ultra or “super-premium in some cases). Most gas stations designate gasoline with an octane level of 89 as “midgrade,” whereas gasoline with an octane level of 87 is known as “regular.”
Can a Toyota Tundra be upgraded?
The new Tundra should only be fueled with 87 octane, according to Toyota. That is the lowest octane that is typically offered. Regardless of the engine you have, you should only use the lowest octane available because the Tundra was made to run on it. Even 85 octane is safe to use if you reside at a high altitude.
What about improved engine performance, though? or more fuel efficiency? These assertions, which are frequently made by gas companies, are false. Using high octane fuel may have a few small advantages, but the additional cost isn’t worth it. You don’t think so? We discovered this post that details precisely why Tundra owners ought not to purchase premium.
However, the Car Guys neglected to emphasize one advantage of premium: The majority of high-octane fuels have detergents in them, which will clean your fuel system. These cleaners are comparable to (but less potent than) a bottle of gas treatment you might get from an auto parts store. Treatments for the fuel system are a helpful form of maintenance. Impurities build up over time at the built-in “choke points” in your fuel system. That usually refers to your fuel pump and injectors. These deposits may eventually clog an injector, lowering fuel efficiency and performance. In fact, the injectors will need to be replaced if they get too unclean. Accordingly, it makes sense to clean your fuel system.
However, the cost difference between a full tank of premium petrol and a full tank of normal is greater than enough to purchase a bottle of fuel system cleanser and manually pour it into your truck. However, that is presuming you will remember to do it. Purchasing fuel system cleaner probably isn’t high on your priority list if you’re like most individuals. Once a year of premium gas purchases will suffice to maintain the fuel system clean if you’re the kind that tends to forget to perform these things.
Conclusion: Adding higher octane has little to no advantage because the Tundra was created to run on regular low octane fuel. There is no reason to fill your new Toyota Tundra with premium gas, unless you don’t want to bother with the hassle of adding some fuel system cleanser to your truck every 20k miles or so. Exxon, be gone!
What kind of fuel is 87 octane?
Measures of gasoline stability are called octane ratings. These rankings are based on the pressure at which a gasoline will spontaneously ignite in an engine under test. Actually, the octane number is the simple average of two distinct octane rating systems. The main differences between research octane rating (RON) and motor octane rating (MOR) are the particulars of the operating conditions. The fuel is more stable the higher the octane number. According to octane rating, retail gas stations in the United States offer three different classes of gasoline:
- Regular (the lowest octane fuelgenerally 87)
- Midgrade (the middle range octane fuelgenerally 8990)
- Premium (the highest octane fuelgenerally 9194)
The octane rating is referenced in all of the names for these kinds of gasoline that certain corporations use, including unleaded, super, and super premium.
A petrol pump displaying several fuel grades and octane ratings on the yellow labels.
The minimum octane rating is shown by the huge number on the yellow octane label on petrol pumps. The octane testing method is identified on the label as (R+M)/2 Method, where R stands for Research Octane Number and M for Motor Octane Number.
The 2,2,4-Trimethylpentane molecule, which is extremely resistant to auto-ignition, is one of the 18 isomers of regular octane (C8H18), which is where the name of the fuel comes from. For testing purposes, this iso-octane has been given the reference value of 100. The 0 octane reference fuel is the exceedingly unstable normal heptane (C7H16) molecule.
