Nada. The octane of the fuel has absolutely no effect on how long your car is going to last. If your car is designed to run on 87 octane then feeding it 89 or higher octane will do one thing: lighten your wallet. There is NO reason to use octane any higher than the engine is designed to run on.
The kind of gas a BMW 328I takes is premium gasoline with a 97 or higher octane rating—in fact, the BMW 328I is one of the few models that BMW actually requires to use premium fuel, rather than simply recommending it.
Can you put 89 gas in a BMW 328i?
The minimum AKI Rating is: 323i,328i/xDrive: 87 335i/xDrive: 89. If you use gasoline with this minimum AKI Rating, the engine may produce knocking sounds when starting at high outside temperatures. This has not effect on the engine life. Do not use any gasoline below the specified minimum grade.
Can I put 93 gas in my BMW 328i?
The short answer is: NO! We do not recommend running low grade fuel in BMW’s.
Can you run 87 in a BMW 328i?
87 is fine in a 328i. I use it whenever the 87/93 price differential gets much above 10% as it becomes more cost effective, even given the poorer performance & fuel economy.
What happens if I put 87 gas in my BMW?
The short answer is – nothing. Most BMWs can run on regular gas so you aren’t at any risk of causing damage to your brother’s car. When you put regular gas in a BMW as opposed to premium, the car will recognize this and may run with a little less power and less timing but all components will work properly.
Can I put 89 gas in my BMW?
BMW recommends that their drivers only use high-octane fuel, such as 91+ octane. This will help ensure you BMW performs at its best, though, as with any fuel option, there are some pros and cons to 91+ octane fuel.
What happens if you put 87 instead of 91?
“If the octane is less than 91, the engine could be damaged and the repairs would not be covered by the vehicle warranty. If heavy knocking is heard when using gasoline rated at 93 octane, the engine needs service,” the owners manual reads.
Do you have to put 93 in a BMW?
BMW requires 91-octane fuel at a minimum, with 93 recommended, so we did just that, switching between the common forms of premium gas depending on which state you’re in.
This makes high-octane fuel better for engines that create higher cylinder pressures during the combustion cycle. We call these “high-compression engines” for obvious reasons, and while some BMW engines do use very high compression, not all of them do.
Luxury cars may require premium gas if they have a high performance or turbocharged engine. Even if you’re not buying a luxury car, more luxurious trim levels for a car may offer engine options that require premium gas.
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
What gas station does BMW recommend?
What is it about Shell that they like? Because Shell paid more money to be the official fuel recommended by BMW. It’s all about the marketing dollars and has nothing to do with the product being good, bad, or better. Because Shell paid more money to be the official fuel recommended by BMW.
Is Costco gas good for BMW?
We use Costco gas in all our BMW and other cars. I even use it in my Bmw m8 v8 with twin turbos. It’s perfect and works well. Kirkland Signature gas meets all Top Tier requirements, including Regular, Premium and Diesel.
Gas stations in the United States generally offer three octane grades: regular (usually 87 octane), mid-grade (usually 89 octane), and premium (usually 91 or 93 gas).
That variable-octane recommendation gives you the option of choosing lower pump prices or higher performance. You’ll get slightly worse fuel economy on regular grade, but that fuel’s lower price will likely make up the difference.
In short, yes, you can usually switch from premium to regular gas for a short time**. But if your car requires premium gas, then your engine may start to underperform. Many people get confused about the difference between premium and regular gas, so it’s hard to understand why some cars require one or the other.
What happens if you put 87 instead of 93?
In most cases, the vehicle will run fine, but you may experience less power and a decrease in gas mileage. In more serious cases, you may hear engine knocking or valve chatter because the fuel isn’t burning right. These things could damage your engine and you should take it to your mechanic.
Other things to consider: failing to use high-octane fuel in your premium vehicle could cause engine knock or pinging, which sounds like there’s a large woodpecker under your hood; you could experience damage to your components; and using the wrong octant level could even void your warranty.
Can you mix 87 and 89 gas?
Is it okay to mix 87 octane and 89 octane fuel together in my car? Yes. You will not harm your car by mixing different octane grades of the same gasoline providing your car’s engine is designed to run on less than 89 octane fuel and you are not using E85 in a non-E85 compatible engine.
Can I use 89 octane instead of 93?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
Is there a big difference between 89 and 91 octane?
The higher the fuel octane rating, the less noise will be noticeable on combustion. Additionally, octane levels also reflect the fuel’s burn-rate. Regular 87 fuel burns slower than Premium 91 fuel, which will burn hotter and create more combustion.
Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbochargers or high-compression engines, so you can hit that horsepower smoothly. Additionally, premium gas can increase fuel efficiency, potentially bringing better gas mileage for longer while decreasing emissions.
Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. In engines designed for standard unleaded fuel, efficiency and performance is optimized for 87 octane and could actually perform worse with higher-octane fuel since the burn rate is slower.
