I pretty much hold on the underground tanks being about 55F constant. I don't worry about "overfilling" as the distance home or into town from my usual station consumes about a half gallon within 20 minutes of my having filled.
I do hold to variations in tire pressure at very cold or hot summer temps. I suppose my biggest fuel tip is there are stations that take manual "stick" readings of their tanks. This I think is an EPA requirement as they keep records should an underground tank be leaking. Something I've seen at several stations is the attendants sprinkle Comet cleanser or "Barkeep's Friend" on the stick to see an accurate reading. Maybe it's nothing but I can't ignore the accumulated abrasive that must be suspended in the fuel. > From: Fmiser <[EMAIL PROTECTED]> > Reply-To: Mercedes Discussion List <mercedes@okiebenz.com> > Date: Sat, 5 Jan 2008 21:45:14 -0600 > To: Mercedes Discussion List <mercedes@okiebenz.com> > Subject: Re: [MBZ] Supposed Tips on Fueling Up > > It seems than at Fri, 4 Jan 2008 03:13:17 -0800, Zoltan wrote: > >> Now, I don't want to be one of those folks who perpetuate >> forwarded emails, but I just read this one and I bet y'all >> could provide great feedback. > > Interesting reading. > >> *Only buy or fill up your car or truck in the early morning >> when the ground temperature is still cold.
