What type of gas mini cooper

When it comes to premium vs. Octane ratings denote the pressure under which gasoline will combust. In other words: the higher the octane level, the more stable the fuel.

Depending on octane level, any gasoline you buy in San Diego receives a rating of regular, premium, or ultra-premium:. Higher octane fuel causes engine combustion to occur later. Some engine knock is normal, but engine damage may occur if the knocking becomes chronic. That said, it may be best for your vehicle to use premium fuel if:. Consider it a fast lane to the nice list.

Manual says that cooper s minimum requirement is 89 octane and regular cooper minimum requirement is 87 octane. It is recommended to do the higher octane for better preformence and operation, if you can afford it go premium. If not try 89 and 87 accordingly.

A higher octane fuel is needed because counter intuitively a higher octane fuel requires a higher compression to ignite compared to a lower octane.

The high compression of the sport model mini's can cause the fuel to burn at times outside of when there is the spark. This is known as engine knock and can be damaging to the engine. If you switch from 91 to 89 it should be ok because those are both within spec to run in the engine with minimal knock. If you switch to 87 you increase your chances of engine knock.

Didn't know about the higher octane fuel. On my way home from the dealer filled the tank with 87 octane. Ran down to about a half tank until check engine light came on. Filled with93 and light eventually went off. No problems since. Sorsha answered 2 years ago. I was about to post myself what an absolute dick Markw was. What an unnecessarily condescending asshat. Should be shot in the street.

So the higher octane means it is more difficult for the fuel to burn, with a typical gas cycle this means this would only be when your spark fires. Knock happens when the fuel ignites prematurely from the pressure. I do get the timing of when you had issue just happened to be at the same time as the fuel change but a issue with engine knock would not come from a too high octane level. Beyond that, I cannot speak towards the electronics in the mini itself, I can only speak from a fuel understanding.

Hopefully that helps. GuruHB4GY answered 2 years ago. The octane rating system in the Europe and North America are completely different. Do not compare them. It's like comparing Celcius vs Faranheit. Europe ratings are in RON. North America is in AKI. You also do not NEED premium fuel in your Mini, especially in the winter months where pre detonation is unlikely. Your car's ECU will detect the knocking and retard the timing and adjust the air fuel mixture automatically.

This applies to most BMW engines as of , and all current engines. BMW's are sold and can be popular in many countries which do not have access to premium fuel, the engines are designed to accommodate these circumstances. However with regular fuel your performance and fuel economy will be affected. If it's very hot weather then Premium fuel will net you savings in fuel economy. I appreciate your input. My question then is what type rating is used in the manual for the car when purchased in the united states.

I included a picture of the manual from my mini s is the manual changed between the different countries? It is a shame that the type of octain scale Ron,Mon or AKI used was not mentioned in the user manual for the vehicle. If anyone has a more in-depth operation manual for the Mini a picture that includes the octane units would be greatly appreciated. GuruH8GNH answered 2 years ago. Elevation plays a small role in what octane you car can use as well. The higher the elevation the lower octane is needed.

For every ft of elevation your octane requirements drop by 0. So at sea level, if your car requires 91 it only needs 89 at ft above sea level.

Not a huge difference but thought I would add to the conversation for the people who live where the air is thin :. Alex S. December 28, You will never want to use diesel or E85 in Your vehicle because it can destroy the motor or the fuel system.

I recommend always getting the highest octane rating that You can afFord. The higher the octane the cleaner the burn in the engine.
