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.ib516 wrote:

Might not be so for diesels, but every gas powered vehicle has a warning in the manual about not overfilling the tank, stop when the pump clicks, etc. etc.
I am sure it says the same for diesels. It’s a CYA rule. Like I said GOD forbid any hits the ground.
Costo pumps say no topping off. One reason they want people to get in n out FAST.Fordlover wrote:

Ridiculous way to SUPPOSEDLY fill all their tanks the same. So take those numbers with a grain!
Three different drivers and fuel tank fillers, HMMMMM.
So people say Diesels are expensive to operate, REALLY??? 91 octane is well north of Diesel pricing.
Little trailer like that and they can't get over 9.8? Flat land towing like that I would get 10.5 at 33k combined.
I guess that depends on what prices are in your area. It's not unusual here in truck country for Premium fuel (93 octane) to be less expensive than Diesel. Last I checked Diesel was an 80 cent premium over regular, and typically I see a 40-50 cent premium for 93 over regular. Don't forget the DEF.
None of which matters if you are towing heavy enough to need or want diesel.
You are correct. Really matters more about region.- Some of you beeching about prices, IE Pennsylvania prices listed, add $.60-1.00, and you have prices in Puget Sound. Western states when I see pricing are usually highest, mid west, then east coast cheapest. California usually highest.
I'm still on lookout to replace my 2500 with something that gets in the upper teens for mpg empty. A diesel is not in cards. Probably a GM 4.3. The frod eco in transit at work has yet to get me 19mpg running empty to maybe max gvwr, much less towing with no hitch on it!
Marty - PA has the highest gas taxes and next to highest diesel taxes in the nation. Don't expect anything to change soon. I live close enough to the MD line so I have bought exactly 1/2 tank in PA in the past 2-1/4 years.

I also had a 2011 F150 with the 5.0
I went with the 5.0 after the 08 5.4 I had and both sucked more gas than I care to remember...somewhere in the 7's towing pop-ups.
When I got the 11 3.5 it was night and day power to both the 5.4 and 5.0 towing
My 11 3.5 I have towed the trailer in my sig over 40k miles now and avg a constant 10.0 MPG's using 91 Octane or higher as it does give more power and better fuel economy by a .5 MPG for me.
My 18 3.5 I have towed the trailer in my sig over 7k miles now and avg a constant 10.5 MPG's using 91 Octane or higher as it also gives more power and better fuel economy by a .5 MPG for me.
I tow all over the northeast in the appalachians of Pa, WV, Virginia, and North Carolina.....alot of towing time in the blue ridge mountains.
Will I ever go back to the Naturally Aspirated V8 in a half ton.....NEVER
The 3.5 eco just tows that much better.
As for fuel prices in Pa 87 gasoline is around 2.55 91 is 2.85 and diesel fuel is 3.65 per gallon. The diesel would have to do much better than 3mpgs for me to ever justify the price difference plus the DEF and those killer emissions
That is my real world mpgs with my setup
Oh and I always tow with the cruise set around 65mph too
I understand you are only detailing pricing in your area, which is all you can do. However PA has some of the worst fuel prices of the surrounding states. Here in MD diesel is 2.85 and premium 3.05 regular is 2.29. Those numbers are quite different from your current pricing making the gas vs. diesel analysis favor diesel by a long shot.
However give it a month these figures can all change.
At the end of the day. If you tow/drive an RV you are going to spend some $$ on fuel regardless of your vehicle.
In my book there is no such thing as an efficient RV tow vehicle.
My diesel dually is basically as good as it gets!:R.....and it's not necessarily good:SCummins12V98 wrote:
