2004 A4 3.0 Cabriolet fuel grade recommendation

Aug 25, 2005 0 Replies

Hi, I've just purchased a used A4 V6, and I'm surprised that an engine of that size requires Premium 91. I understand it is more sensitive on an 1.8 Turbo



What would be wrong with 87 or 89?



Thanks to share your opinion.



Regards.
