Up to 15.8 gallons of premium fuel with an octane rating of 97 or above can be stored in the BMW 328I. Premium fuel-requiring automobiles need higher octane levels to ignite, while upmarket vehicles frequently use a turbocharged engine or increased combustion chamber compression. It is not advised to use regular fuel in engines made to run on premium unleaded gas because doing so could eventually cause the engine to perform worse and even break. With a combined mpg of 27, the 328I achieves 35 mpg on the freeway and 23 mpg in the city. The 2.0 liter, 4-cylinder engine in the BMW 328I produces 240 horsepower and 255 lb-ft of torque.
Unleaded gasoline with an octane level of 91 or above is the recommended fuel type for the BMW 328i.

The Drawbacks of Filling Your BMW With Regular Gas
Buying expensive gas for your BMW or any other vehicle might be costly. You may be able to save money by using ordinary fuel depending on the model of your BMW, but there will be a cost. We think that saving money right away isn’t worth endangering your car.
Thanks to more electronic components, most new BMWs can run on ordinary gasoline, but this might put stress on several elements, including the electronic knock sensors in your engine. These electrical parts provide the engine the ability to recognize the sort of fuel it’s using and alter performance accordingly, protecting your engine.
Regular fuel has the additional drawback of altering the performance of your engine, which results in a reduction in power and slower acceleration. But this isn’t a significant loss. Most vehicles that are advised to use premium fuel but switch to normal gas will lose around 10 HP. This is something to keep in mind, especially if you bought your BMW for its power, even if it probably won’t be a major concern if you only use it to get around town.
There are some exceptions to this rule, just like with anything. Certain BMWs do need premium fuel.
These are the most typical causes for a BMW to need premium, but this is by no means a complete list. In the event that your BMW fits one of the following descriptions, avoid using normal gasoline in it:
- Your vehicle predates the 1996 model year.
- It’s a model M.
- It has a turbo engine or one with high compression.
- Your model of vehicle must utilize premium gasoline, per BMW (they recommend that all of their cars use premium, but only require it on select models)
A complete list of BMWs (model years 2012–2019) that demand premium can be found here, while a list of BMWs that recommend premium but can operate on regular can be found here. Remember, though, that continuing to run as usual can have negative effects. Above all, before converting from premium to normal unleaded, always consult your owner’s manual.
Can ordinary gas be used in a BMW 328i?
A BMW 328I requires premium fuel with an octane value of 97 or higher; in fact, the 328I is one of the few vehicles for which BMW mandates premium fuel usage rather than just advising it.
Can 89 octane fuel be used in a BMW 328i?
The quick response is: NO! We do not advise using subpar fuel in BMWs. When reading the owner’s manual for some models, this might seem like a good alternative, but Triangle Imports doesn’t subscribe to that way of thinking. The potential harm that conventional petrol could do to your car is simply not worth it.
What happens if I fill up my BMW with 87 gasoline?
323i,328i/xDrive: 87; 335i/xDrive: 89 are the minimum AKI ratings. When starting the engine at high outside temperatures, the engine may make knocking noises if you use gasoline with this minimal AKI Rating. The engine life is unaffected by this. Use only gasoline that meets the required minimum grade.
Can I fuel my BMW with 89 octane?
The quick response is nothing. You won’t run the risk of damaging your brother’s automobile because the majority of BMWs can run on ordinary gas. The BMW will identify when you use standard gas instead of premium and may operate with a little less power and timing, but all of the components will function as intended.
Why does a BMW need premium fuel?
A standard grade 87 or 89 is advised for the majority of vehicles on the road. It’s perfectly fine to fill a normal vehicle with premium gas between 90 and 93. According to auto experts, using premium fuel in a regular car poses little risk of damage.
Can BMW use ordinary gasoline?
Chevron, Conoco, Exxon, Mobil, Phillips 66, Quik Trip, Shell, and Texaco gas stations are Top Tier compliant. These petroleum firms spend money to get their fuel examined and authorized in accordance with strict Top Tier criteria.
What happens if I don’t fill up my BMW with premium fuel?
No matter what model you have, BMW advises only using premium unleaded fuel. That’s not to say that your BMW won’t run on inferior fuel, but premium unleaded fuel will keep its quality over time, allowing you to constantly drive at peak performance.
Which gas station is ideal for BMWs?
There are typically three octane ratings available at gas stations in the United States: ordinary (often 87 octane), mid-grade (typically 89 octane), and premium (usually 91 or 93 gas)
Can I fuel my BMW with 93 octane?
91+ octane fuel is the fuel created exclusively for use in BMW high-compression engines. Because it optimizes engine function and reduces fuel waste, you can travel farther on a single tank of gas, increasing your miles per gallon.
Is Costco fuel suitable for BMW?
High performance engines frequently use premium gas because of its higher octane rating. The fuel has superior balance and stability against spontaneous combustion with a higher octane rating, which can prevent engine knocking and harm to your car.
What occurs if 89 fuel is used in an 87 vehicle?
No, premium fuel does not keep running longer in a fuel tank than conventional fuel. If a car has been idle for a while, the owner might start thinking about how long a tank of gas will last.
Is 89 premium gasoline?
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 could harm your engine.
Is premium fuel preferable?
As opposed to standard octane, which has an octane rating of 87, premium octane has an octane rating of 91 or higher. Because premium gas has a higher octane rating, it is more resistant to early gasoline ignition, which can cause possible damage and occasionally be accompanied by loud engine knocking or pinging.
Can 87 and 91 gas be combined?
BMW, for instance, advises using premium fuel in all of the vehicles it sells in the United States, though they can also run on ordinary. According to Thomas Plucinsky, a BMW representative, using lower-octane fuel normally doesn’t hurt the engine.
What happens if I fill up with regular gas once instead of premium?
According on the state you’re in, we switched between the common types of premium gas to meet BMW’s minimum and recommended 91-octane gasoline requirements.
Is premium fuel more durable?
Your car’s ECU will modify engine timing and performance to work with the lower-octane fuel if you accidently fill up with ordinary petrol. Most of the time, this is acceptable for situations where there are no premium fuel pumps nearby, but using the cheapest fuel for extended periods of time is not recommended.
Does the difference between 87 and 91 octane actually exist?
It won’t hurt vehicles made to run on regular gasoline to mix regular or mid-grade gasoline (87-89 octane) with premium fuel (91-93 octane). Nevertheless, depending on the vehicle, blending various types of gasoline in vehicles made for premium fuel could cause engine knocking and fuel system damage.
What occurs if you enter 93 rather than 87?
A standard grade 87 or 89 is advised for the majority of vehicles on the road. It’s perfectly fine to fill a normal vehicle with premium gas between 90 and 93. According to auto experts, using premium fuel won’t harm a basic automobile in any way.
Contrary to what you may have heard, standard gas today contains the same detergent chemicals, thus using premium gas won’t do more to remove deposits from your fuel injectors or other components of the fuel system.
Experts advise against using fuel other than that advised by the manufacturer in high-end vehicles.
Let’s first analyze the distinction. Regular gas is typically 87 octane, midgrade gas is 89 octane, and premium gas is over 91 octane. Some states designate premium gas with a 93 octane rating as “ultra” gas.
The lowest type of regular gasoline is chosen in this situation since it is the most affordable option at the gas station given the rising and high cost of gas.
The World Toyota Service Center claims that lower octane fuels can induce pre-ignition, which would sound like a knocking in a high-end vehicle. They claim that this could harm your motor and possibly even the computer in your automobile.
“Older cars sometimes have an audible “pinging” or “knocking” sound coming from the engine. Several more recent cars can alter the spark timing to lessen knock, but the engine’s performance and fuel efficiency will still suffer “described by Fueleconomy.gov.
In their owners manual, General Motors cautions that using standard grade petrol in an engine that needs premium could also void your warranty.
“The engine could be harmed if the octane level falls below 91, and repairs would not be covered by the car guarantee. When using gasoline with a 93 octane rating, the engine needs to be serviced if there is loud knocking “Reads the owner’s manual.
Therefore, we can VERIFY that you must purchase premium if the car’s manufacturer does. If it suggests a lower grade, there is no difference in effect between normal and premium, other than the cost.
Look at the label inside your driver’s side door or consult your car’s owner’s manual to see what octane level it needs.
