#1329 of 1330 Additives & Fuel problems
May 15, 2013 (4:59 am)
I have a 2002 Honda Accord 6 cyl and its in Florida. I've heard that in hot areas you should try to keep a full tank of gas to prevent condensation in the fuel tank. It this a myth or truth? I just filled it up and noticed an engine knocking at acceleration. Will a fuel additive help with this by chance? I love this forum. It's always been a great help. Thanks!

With all the vapor controls on cars, you don't need to worry about condensation. And worry even less in hot areas, not much condensing going on, anyway.
As for the knocking, if it's loud get to a mechanic soon. If it's barely noticeable I'd try filling up with premium after it gets to a half tank and see if it goes away.
Is the 'check engine light' (or any warning light) on?
