Unleaded or Super

I would like to try rocket fuel in mine. But I fear I'd never be able to stop.
 
I usually use BP Ultimate or Shell V Power.

To be honest, on the rare occasions it's been fed "normal" I never noticed any difference.
 
Personally, I use V-Power every time, as I don't do much mileage.

But run a tank of 95 RON through your car and log the timing correction. You'll see barely any at all. Your BMW is designed to run on whatever sh*t fuel the country the car was delivered to would just so happen to pump out and has to be able to run on the poorest quality fuel that's been in the tanks for weeks of the most desolate un-used petrol station on the planet without causing damage to the engine.

That said and done - If you love the car, give it the best fuel :)

I see nothing wrong with revisitng the topic from time to time for the benefit of new members. If people disagree or have issues with it being revisited again, then they don't have to read it.

Rant over :)

Rant away Brian - we all need a rant somtimes :wink:

On a constructive note - I did offer lots of background reading so that the OP could read some of the previous discussions to better inform the decision making process :thumbsup:

'Cos I'm helpful like that innit 8)
 
I do fill my Zed with 98+ octane fuel... Preferably "OMV MaxxMotion 100" (Czech, Germany, Austria) or any 98+ octane anywhere else. I did fill it with 95 octane fuel a few times and noticed slightly uneven run when idle... otherwise not much difference. But I love the car, so what the heck, I give him the best available... I want to eat the best, why shouldn't my car :)
 
There is also a school of thought on the standard of the fuel, as well as the RON - and particularly referencing additives. You can spend a lot of time researching, asking questions, getting confused..... but in the end it all boils down to personal choice.

Here's my logic; I don't shop for food in certain supermarkets as the quality isn't as good, and I like food to be best quality, not a filler. Food is a pleasure, and I prefer to pay more to eat and savour food. Others would differ, and that's their choice. My choice is to go for quality, as IMO life is too short to scrimp on the pleasures, and I pay for the quality that I can afford.

Its similar for my car - the DD gets supermarket fuel, as its a high mileage cruncher and if it goes I replace it with another. My zed, however, is a different matter - its a performance car, a hobby, one of my (main) pastimes, and one of my pleasures so I take care with it and invest in it. It gets serviced at reputable garages, by mechanics I know and trust. Parts are always OEM or better, and fluids are highest quality - including petrol. Financially it might not make sense, and I may not get the mileage/performance/investment returns out of it, but that's not what I am looking for.
 
yay a petrol post

can you really call the quality of fuel into question in the same way you would a carrot? its all made to the same BS standard is it not? the only major difference being the additives and age. so fuel from supermarkets will be the same BS as that from shell. maybe the age is different. i did read alot about the supermarkets buying on a market that was basically fed by the big producers when their fuel is a certain age. cant remember the specifics but its something daft like the base fuel from shell is made on day 1and used only by shell then on day 7 whats left in a tank at the refinery is then sold on the open market to everyone else. respective additives are added at the point of it going into the transport tanker.

As for the ron rating the hand book for my 3.0i says 95 or higher. i believe the N52 is 98+. just to add confusion my filler cap says 92-100!

Yes, IMO. So I did. :)

Just because its BS, doesn't make it quality. As I mentioned, there is a lot of conflicting information out there about how supermarket fuel is blended from all the major suppliers, and then additives mixed in to raise the RON level/add detergents etc. Hence my food analogy. A carrot is a carrot, irrespective when you get it from. It meets certain standards, but they definitely taste different depending on where you buy them!
 
The BS number just means the fuel has reached a MINIMUM standard.

It's no different to the food standards agency saying a sausage must contain at least 15% meat to be called a sausage. Would you prefer a 'butcher's choice' sausage with 20% pork or an 'extra special' 90% pork sausage - both exceed the minimum requirements.

I'd go for the 99 ron sausage everytime, they have more detergents in them as well :)

In 2040 threads like this will not exist. Unless it is 'Supermarket Electricity is no where near as good as Shell SuperPositive 240v with Extra Electrons'.
 
Super for me I'm afraid.
I did put tank of normal unleaded in the other day as I was caught short and the throttle response was noticeably worse, as was the low range pickup.

I've used super in mine since I've had it, and it seems to pop nicely on the over run as a result :)

I usually use Sainsbury's super and it pops loads. Have not compared it to shell or 95 thought.
 
I was just about to post on this topic.
We've literally just come back from a very long run (from Lincolnshire to down to the Black Forest and Switzerland). As the filler cap says "Minimum 95" and I'm a tight git I never believed in putting anything more expensive in. However, accelerating at high speed/load I noticed a slight roughness. I changed to Super and the difference was pretty much instantly palpable! Absolutely smooth running engine throughout the rev range and even accelerating up inclines at triple figure speeds.

No more 95 for me from now on.
