In one of the recent issues of European Car, an article mentions (in passing) that the Audi V6 had been modified in (late?) '95 to no longer need high octane gas. My A4 manual still recommends 91 OCTANE. Wonder if the Manual has not been updated yet, or if the article was wrong. Does anyone else have any info on this? I will check on the issue and page number for reference. Thanks, Byas
