[minimat]

Does anyone else find that their injection mini runs better on some manufactures petrol than on others?Some people have said that some petrol does funny things like make their mini hunt at idle etc and that some give better acceleration /power than others does anyone else experiance similar things.Ive heard Tesco super is good but not tried it.

not really. i use shell vpower or whatever it is, the only thing ive noticed is that i run out of money sooner.

Never noticed any differences in petrol in the mini but the bmw hates cheap petrol. The last time I filled it up with Tesco 95, i thought i kept leaving the handbrake on

You'll not get that at Morrison's every morning

I did go through a phase of keeping mpg figures; I found Shell Optimax (as it was then) made the car feel smoother, but actually lost about 5 - 10% on mpg.

My old company car was like a ballistic missile on Vpower / optimax, but ran like a pig on tesco's special mix. My fleet manager gave me a real hard time because he wanted us to use the cheapest possible, even though it felt like it was killing the car.

The ECU learns the fuel you are using and adjusts the running of the engine accordingly so if you go from premium 98ron to regular 95ron then you will notic the mini will run rough for a while whilst it learns the optimised settings for that particular fuel

Also Morrisons buy a much cheaper grade of Petrol which is very bad for the engine.

The Mini ECUs are NOT that clever. The ignition timing is NOT adaptive

I normally go for shell or BP petrol, on the 95 or 98 RON, and then top it up with some Wynnes Fuel additive.

Gives the car a bit of a better kick.

However lately regardless of what fuel I stick in the bugger, I can't get it to run right
