Good point. I should have been clearer...

I'm aware of the charcoal canisters of modern gasoline powered cars/trucks. I make it a rule to never fill more the the second "click". After the fuel pump clicks the first time I wait 10 seconds then hit it one more time. Normally gets a me 1/3 gallon extra. I have never and will never fill to the brim on my gasser.

Little things I miss about my diesel...

I've always over-filled my gasoline and diesel vehicles, and never had a problem. However, I never fill up at the end of a drive. The tank isn't "overfilled" long enough to be a problem.

Some can't really be over-filled. I have a 2010 Transit Connect van, and cannot squeeze in more than an extra pint or so after the pump clicks off. "Full" really is "full."

My 2007 Honda Accord, on the other hand, takes 2 1/2 GALLONS of extra fuel until it's literally brim full. And has been doing so at every fill up for 250,000 trouble-free miles. That's an extra 70+ miles of range from a tank. I go well over 100 miles before the needle drops to FULL.

It is theoretically possible to drown your carbon canister, but you really have to work at it. Over-fill on a hot day and then immediately park in the sun? That might cause a problem. Or spill diesel fuel on the ground, in the case of an over-filled TDI. But it's not going to be an issue if you start burning the fuel right away.

There is no canister or evap system on a diesel . . . diesel vapor pressure is too low to need it . . .

Same here... At least until I got my Jeep. If I go beyond the first click, Diesel goes everywhere. The Jeep is the first vehicle that I have experienced this.

I don't have my Golf anymore, but I am still a religious reader of this thread and still a Diesel fanatic.

Sadly, here in Chicago, no one gives a crap about what you put in your vehicle. So no new stories from me.

I was at a gas station the other day when I saw a beautiful white Smyth ute tdi pulling away. For a moment I thought about running after him to get a better look, but it was too damned hot out. It was only the second one I have seen in person, and the first in Maine. The first one I saw was runonbeer's down in Austin. Both examples were very clean and well executed. A younger guy pumping gas into his jetta also noticed the Ute and me staring after it. He was a bit bewildered when I told him it was a chopped jetta.

After we bought our Passat in 2013 (our first diesel) I read with some bemusement the anecdotes posted by people while fueling their vehicles. We have now owned the Passat for 4 years and have around 61K miles on it, and I have yet to be approached by anyone making a comment about having a diesel, or "you're putting the wrong fuel in your car," or any such thing.....

yeah same here, however many times Ive been at a heavily trafficked road side fuel station and pulled up to the Diesel Island, only to have a bunch of cars follow my lead and pull their gassers up to the diesel only pumps so they dont have to get in line at the gas island... I usually make some smart-ass comment, 'Oah thats awesome Honda is making a Diesel Minivan' before they look around and 'oh crap, is yours a diesel?'

Ive saved more people from trying to put Diesel into there Gasser than Ive had anyone comment on me putting Diesel into a Volkswagen.
