NEVER heard of such a thing. No topping off is so GOD forbid some hits the ground.

I have filled to the top on every vehicle I have owned gas or diesel since 1974. Right or wrong never had an issue.

So you mean you consider "to the top" to be fill it up until you can see fuel in the fill tube? Oye. Or maybe I am still misunderstanding what you're saying.

That is a terrible advice to give anyone with a gas vehicle. You can definitely fill the carbon canister with fuel that way. Not sure what kind of EVAP system they have on diesels.

TFL has some holes in their testing method, but they way they fill is about the most consistent you can do from what I can tell.

Newest gasser I have owned is a 99 Tahoe. Never been an issue filling it to the top.

No idea about anything else.
