can you put ultra 93 in any car

[BryceLynn]

You can physically put 93-octane premium gasoline (often marketed as "Ultra 93" or "93 Premium") into any car that runs on gasoline, but it is not necessary or beneficial for most vehicles. For the vast majority of cars designed to run on regular 87-octane fuel, using premium 93-octane provides no performance or mileage benefits and is simply a waste of money. The key is to follow your vehicle manufacturer's recommendation, which is found in your owner's manual or on the fuel door.

Octane rating measures a fuel's resistance to "knocking" or "pinging," which is premature combustion in the engine. High-performance engines with high compression ratios or turbochargers require higher-octane fuel to prevent this damaging knock. However, engines designed for regular fuel have built-in sensors that adjust timing to avoid knock; they cannot take advantage of the higher octane.

Using a higher octane fuel than required will not harm your engine, but it won't clean it any better either. Modern detergent additives, required by law, are present in all grades of fuel from Top Tier retailers. The best practice is to use the octane level your car's manufacturer specifies. If your car requires premium, it's a necessary expense for performance and engine health. If it calls for regular, you're getting everything you need at the lower price.

Vehicle Type	Recommended Octane	Using 93 Octane Effect	Key Consideration
Standard Sedan (e.g., Toyota Camry)	87 (Regular)	No benefit; wasted money	Follow the owner's manual.
High-Performance Sports Car (e.g., Chevrolet Corvette)	91+ (Premium)	Required for full power & engine protection	Using lower octane can cause engine knock and damage.
Turbocharged Vehicle (e.g., Ford EcoSport)	91 (Premium)	Required to prevent knock under boost	Necessary for maintaining advertised horsepower.
Luxury Vehicle (e.g., BMW 3 Series)	91+ (Premium)	Required for optimal engine operation	Engine computers may reduce power if lower octane is used.
Older Car (Pre-1990s)	Varies	Potential benefit if engine has carbon buildup	Consult a mechanic for specific advice.

As a guy who's been driving the same pickup truck for a decade, I stick with regular. The manual says 87, so that's what I use. I tried premium once to see if it would help on a long haul, and I honestly couldn't feel a difference. My wallet felt the difference, though. It's an extra few bucks every fill-up for zero gain. Unless your car specifically calls for it, you're just burning cash.

Think of octane like a diet plan. Some high-performance engines are like professional athletes—they need a specialized, high-octane "diet" to function at their peak. Your average commuter car is like most of us; it runs perfectly fine on a balanced "regular" diet. Putting a premium diet in a regular car doesn't make it an athlete. It just means you spent more on lunch. Always check what your car's manufacturer "prescribes."

I learned this from my dad, a former mechanic. He always said, "Your car's computer is smarter than you are about fuel." If it's built for 87, the sensors will adjust the engine to run safely on 87. Pouring in 93 doesn't send a special signal for more power. It's like using premium oil when the standard grade is fine—it doesn't hurt, but it's not doing any extra work. The only time you need to worry is if you hear a pinging sound, which means you might need higher octane.

From a purely practical standpoint, the question isn't about can you, but should you. The answer is no, you shouldn't, unless your vehicle requires it. Premium fuel is a tool for a specific job. You wouldn't use a sledgehammer to hang a picture frame. Similarly, using premium fuel in a car designed for regular is an inefficient use of resources. The money saved by using the correct fuel can be better spent on other maintenance, like timely oil changes, which actually benefit every car.
