My two cents:
After getting my Accord V6 3.0 in August 2004, I started filling HP Power. After the first tankfull I noticed a very funny behaviour:
It took a bit longer in the mornings to start. After the powerplant reached its optimum temperature, I noticed knocking and jerking when the gear used to downshift at lower speeds. Mine is an AT.
I mentioned this at my first free service at the ASC and the first question that the service supervisor asked was if I was using premium fuel.. On my affirmative answer he immediately asked me to discontinue. I was sceptical but did as he told.
All the above ills stopped dramatically. But being sceptical, I tried once again a tankfull with HP Power (I've been fuelling all my cars from this one particular pump only). The symptoms returned. Ever since I don't use premium fuel in Accord and aslo in my other vehicles.. |
