I have just purchased a 320si limited Edition, I was reading the manual and noticed the recommended fuel grade should be 97ron , I ran the tank till nearly empty and filled up with £20 worth of 97ron fuel since doing so the car runs like a Kangaroo on speed , surely this should improve the running of the car ?

Any thoughts on this would be appreciated

Thanks in Advance

Hello and welcome 666 . You can run anything between 95 to 98 ron I believe. I think the newer models say 98 ron in the user handbooks. Why don't you use Shell's V Power on your next fill and report back? If it still 'kangeroos' then we will advise.

You haven't run it too low and picked up all the crap lying at the bottom have you? How many miles did it read to empty before you filled up with this £20?

Ran it down to about 50 miles left on the computer. So should have been ok. Will try a Tank Of Optimax, and feed back.

yeah that should be ok, thought you ran it down to 10 miles left or something. As above try the shell v power stuff. You consider trying some of that redex stuff? BMW dealerships are splashing an all approved by BMW product in there reception areas...

it can take a tank full for the ECU to see the hi ron fuel..

Sould sort its self out..

UP DATE

It would seem that the car didn’t like the 97ron from Total. I took NealP advice and filled up with a tank of V Power at the week end, the car is now running like a dream.

Many Thanks
