When taking the Toyota 86 for a test drive, one of the first things people notice is how swiftly it accelerates. The 2.0-liter, four-cylinder powertrain with a six-speed automatic or manual transmission is the key to this performance. The Toyota 86 can generate up to 205 horsepower when the manual gear-changer is installed.
Owners must always maintain the tank topped off with premium fuel to get the most out of the car’s powertrain. The Toyota 86’s engine has been modified by Toyota engineers to run on fuel with a higher octane rating due to the amount of compression required to get the desired levels of performance. The Toyota 86’s stated performance ratings also heavily depend on how gasoline is delivered to the engine of the vehicle. The Toyota sports coupe may achieve a combined fuel efficiency rating of 24 mpg with the manual transmission and up to 27 mpg with the six-speed automatic, while having 200 horsepower or more.

What if I use regular gas in the Toyota 86?
There is no concrete evidence that the Toyota 86 will suffer harm if the customer selects standard fuel instead of the needed premium alternatives. Regular gas may not provide the maximum 205 horsepower the automobile is capable of producing, and fuel economy may be slightly reduced.
Can I fill up my BRZ with ordinary gas?
“The engine is designed to function with unleaded gasoline with an octane level of 91 or higher,” the Owner’s Manual for WRX and BRZ models indicates. Nevertheless, neither model will suffer from the usage of fuel with an octane value of 87 or higher.
Is 86 and 87 octane the same?
High alcohol content and low octane fuel can hurt engines and limit fuel efficiency.
- Higher concentrations of ethanol at low octane percent 2C are dangerous.
- The Rocky Mountains and the Midwest are regions to avoid.
- At best, gas mileage will decrease by 2%; at worst, a car could be damaged and its warranty will be canceled.
DETROIT Drivers should take caution because not all gasoline is made equal. Paying attention at the gas station as the driving season for summer vacations gets underway can increase your fuel economy and safeguard your engine.
The amount of ethanol added to gasoline and variations in octane level can significantly affect fuel economy and emissions. Using subpar gas could, in the worst instance, nullify the manufacturer’s warranty.
The main dangers:
- Octane rating below expectations.
- bigger ethanol blends
According to Bill Studzinski of General Motors, low-octane fuel with ratings of 85 or 86, as opposed to the 87 for standard gasoline, is widely available throughout the Rocky Mountain states.
The custom dates back to the era of carbureted engines, when using lower octane fuel allowed for more comfortable driving at altitude. The lower octane is unneeded and could be dangerous due to the electronic engine controls that have taken the place of carburetors.
Former owner of a 2012 Scion iQ, Rodney Gutzler of Sioux Falls, South Dakota, remarked, “I felt like a fool.” I was getting 25 mpg in this tiny automobile, which was only meant to get 36 mpg in the city.
According to David Montgomery, a writer for the Sioux Falls Argus Leader, the 85 octane gas migrated from the western South Dakota mountain range onto the eastern plains last year. Since then, a law limiting sales to the west and mandating a warning sticker on pumps has been passed by the state Legislature: “This octane level might not fulfill the manufacturer’s minimal requirements. Before you fuel up, consult your owner’s manual.”
Automobile manufacturers would prefer a complete ban on 85 and 86 octane fuel. According to GM, less than 2% of automobiles in the U.S. have carburetors. The remaining 98% or more have computer controls that can adapt for altitude and need gasoline that is specified by the manufacturer to meet criteria for emissions, fuel economy, and performance.
For drivers who were “knowingly and illegally charged inflated pricing” for 85 octane gas, which is less expensive at the pump than 87, a lawsuit is currently underway in South Dakota.
No gasoline with a lower octane rating than 87 should be used, according to the Scion iQ’s unambiguous instructions, Gutzler added. “I couldn’t identify the pumps where I purchased 85 octane. Who had a clue what we were purchasing?”
The additional potential issue
Higher alcohol mixes are currently less common geographically. However, higher alcohol combinations are likely to grow increasingly popular in order to cut greenhouse gas emissions and increase the use of renewable fuels, in contrast to 85-octane gas, which appears to be losing popularity.
Almost all gasoline marketed in the US contains 10% ethanol. It is designed so that vehicles can run comfortably on it. However, a new 15 percent blend known as E15 may be hazardous. Only a few gas stations, some of which are in Wisconsin and Illinois, sell E15 at the moment.
Automakers dispute with the federal Environmental Protection Agency’s assertion that E15 is compatible with vehicles built after the 2001 model year’s emissions control systems. It wasn’t that long ago that they certified other systems for it.
For instance, GM only approves E15 for model years 2012 and beyond. There is possibility for user error due to the conflicting messages from the EPA and automakers’ guidelines.
As stated by Nancy Cain, spokesman for AAA Michigan, “A recent AAA poll reveals a substantial chance of customer confusion, and the potential for voided warranties owing to E15.” “We want more education so that consumers are aware of what they are purchasing and what their vehicles require,”
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.
What type of gas can an FRS handle?
Depends a lot on where you reside. I am aware that 89 is the standard “Premium” gas in states with higher elevations, thus there are no other options available. The vehicle is perfectly capable of handling 91 octane, but you should be prepared to lose some power because the vehicle will adjust the ignition timing to take into account the less compressible gasoline. Personally, I use BP’s 93 octane, which is also E10. I’ve never changed the gas station I go to unless I’m on a long road trip because she runs fine and I’ve never had the crickets in this gas (Probably just a correlation and not causation but wouldn’t want to mess with a good thing). Even then, I look for a BP that has 93 octane. When I have to fill up with 91 and/or 92, I’ll grit my teeth.
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.

What automobiles exclusively need premium fuel?
A List of 15 Regular Cars That Use Premium Fuel
- Cadillac Envision (with 2.0L turbo)
- Bugatti Regal (all models)
- Chevrolet Regal TourX (all models)
- Cadillac Equinox (with 2.0-L turbo)
- CORVETTE MALIBU (with 2.0-L turbo)
- Fiat 500L (all models)
- Terrain GM (with 2.0-L turbo)
- Honda Accord (with 1.5-L turbo)
Does the BRZ 2022 need premium fuel?
The optimal fuel for each Subaru model is shown here, including ordinary (87), mid-grade (89-90), and premium (91-92). Why does Colorado provide (85) octane, and should you use it?
Do you need the more expensive grade of gasoline given the escalating cost of fuel? If you operate an Impreza, Legacy, Crosstrek, Ascent, Forester, Outback, or Crosstrek? You don’t need pricey premium fuel because your car can run on 87 octane or normal gasoline.
The sport-tuned WRX, performance-tuned WRX STI, and BRZ rear-drive sports coupe from Subaru all demand premium fuel, but even for those models, consult your owner’s handbook to see which fuels deliver the optimum performance.
In the United States, gas stations normally offer three or more fuel grade options that vary by state, and Colorado offers gasoline with an octane rating of 85. Each gasoline grade must be rated by its octane number and displayed on the pump in accordance with U.S. laws. In general, normal (87), mid-grade (8990), premium (9192), and in some states, super-premium fuel grades are the most readily accessible (93-94).
According to a study from Subaru’s Drive magazine, “In order to continuously monitor the state of combustion inside the cylinders, every Subaru car produced over the past 30 years has relied on an engine management system that has become increasingly sophisticated. The engine management system receives data from knock sensors and uses that information to automatically change the ignition timing to maximize fuel efficiency.”
Performance cars like the WRX, WRX STI, and BRZ are built to function properly even when the best grade of fuel isn’t readily accessible, according to a report by John Gray, Field Quality Assurance Manager with Subaru of America’s Service and Quality Department.
“The engine is designed to function with unleaded gasoline with an octane level of 91 or higher,” the Owner’s Manual for the WRX and BRZ models explains. Nevertheless, neither model will suffer from the usage of fuel with an octane value of 87 or higher.
When using a lower octane fuel, you can notice a slight decrease in performance, but the car will automatically change the timing of the engine to prevent preignition.
What kind of gas can a BRZ run on?
The Subaru BRZ should be filled with 91 octane fuel for the optimum performance and a longer expected engine life, and a level of 93 octane fuel is actually advised for the best in performance and efficiency.
How fuel-efficient is an 86?
The 2020 Toyota 86 has some amazing fuel economy statistics, to say the least. The base trim gets 21 mpg in the city and 28 mpg on the highway, respectively. The 86 GT with automatic transmission trim, on the other hand, has fuel ratings of 24 mpg in the city and 32 mpg on the interstate. This trim level will only set you back about $2,000 more than the lowest trim level, so that’s a significant increase. It’s a great offer!
