I'm driving a 2007 civic auto and whenever I use 91ron fuel, there is a rattling (more like clicking) for a few seconds when I accelerate slowly. More noticeable if I'm going up a hill after a stop. From what I know, alot of 8th gen Civic auto is having the same problem aswell. I went to my dealer the first time and to a different honda dealer the second time and had my car thoroughly checked for timing, such and such, and they couldn't find the problem. The only suggestion they made was to fill up with 98ron petrol as the problem dissapears after using premium petrol. << all this happens before I had my 20k service..
However, after I had my 20k service, the dealer used a different brand of engine oil (I think its a Honda premium oil) and the problem dissapears. My car used to have a Castrol oil when the problem occurs. I'm happily using 91ron petrol now whenever 98ron is too expensive.. lol
Hope this helps..
