Thanks Ted appreciate the help.

I wonder if GVWR is jurisdiction/licencing driven? I got quotes for identical trucks except box length. There was a couple of hundred dollars difference but the GVWR was identical at 11,500 lbs.

Well............. I received a Ford recall re the tire loading information sticker. "the payload capacity value.....may be overstated." "If the vehicle is loaded to the payload stated, the vehicle may exceed its Gross Vehicle Weight Rating(GVWR) or Gross Axle Weight ratings(GAWR). This may result in tire loading beyond rated capacity, suspension overload and increased stopping distance, increasing the risk of a crash." Now I don't know what the correct payload information should be for my particular truck. I have not contacted the dealer for a new sticker, yet. Something else to take care of.

FWIW

Hi Jim,

Yes, I ran regular for ten months and it was fine. The Ford manual says there is a benefit for premium gas when towing. An automotive engineer on another site explained that the computer-adjusted timing was able to be more advanced with the higher octane and produce more power. Premium seems to run about one gear higher under load on hills when towing. That is about as much as I know about the tech side of this, but it does seem to have more power.

Best,

Charles

Update
Just got an apologetic call from one of the sales folks. Ford Corporate evidentially is putting a hold on all a,z,d,x plans until such time as the inventory on hand gets shipped, so I am going to delay my order. Not going anywhere so I don't need the new truck yet, plus it would show up in the middle of winter here. Also got thinking that once the new/old inventory is shipped the incentives will begin again. It will also allow the GVWR issue to resolve itself.

Thanks for all the help folks

More news as I here.

Not to be negative, but why not just go to a CAT scale, and find out what your payload is, you don't need a new sticker for that.

I have been looking at Ford F350 long beds, and actual payloads from the factory is around the 4,200 lb area or less, depending of course on how equipped.

Don't care what my payload is. Wanted to know the rating numbers, the sticker numbers. I know I am loaded light.

You do need the rated numbers, the sticker numbers, to know if you are over- or under-loaded after getting the CAT scale numbers. Otherwise what's the point of getting actual weights?

Charles,

I read a post on another site where the verbiage may indicate that Ford is relying on the knock system for hot weather and high loads rather than using tables + the knock system. This would be a change in strategy and if the knock system is robust, this would work well. I calibrated GMs performance cars (and others) as well as combustion analysis on those in addition to testing competitor apps. Can you post the language from your manual? To the calibrator and the EPA, this language can be carefully crafted where a calibrator can read deeper into that to understand their control system.

If Ford is claiming regular recommended, then the engine was certified to regular fuel. But there are caveats to this. In hot weather, spark advance must be pulled in addition to heavy towing where cylinder temperatures will increase and raise the propensity for knock. I'm interested in their strategy which I'm sure GM and Stellantis and others have already tested. Powertrains have always interested me and always will I suppose.

Take care,

Jim

I am not sure what you are calling the rated numbers, I am guessing the GVWR, and the GAWR, which you already have on the sticker. The recall is only for the available payload weight (GVWR - truck weight) on the sticker, not the GVWR (12,400 lbs), or the GAWR (6,000 lbs front, 7,230 lbs rear), they have not changed.

When you get a new sticker (tire and loading information label) from Ford, the only numbers different on it will be the payload capacity on it. Someone missed math class, or the scale was off.

Wileykid , I'm saying rated numbers = sticker numbers. Yes, as noted in post #18, the recall is for the sticker payload number. "the payload capacity value.....may be overstated."

Hi Jim,

I could not find the other quote, but here is the Ford manual. It seems that the computer does adjust the spark based on altitude, temperature, load and octane.

I suspect the 430 HP rating by Ford was done on a 7.3 with premium gas, but that is a guess.

Best,

Charles

FUEL QUALITY - GASOLINE
Choosing the Right Fuel
Your vehicle is designed to operate on regular unleaded gasoline with a minimum pump (R+M)/2 octane rating of 87. Some fuel stations, particularly those in high altitude areas, offer fuels posted as regular unleaded gasoline with an octane rating below 87. The use of these fuels could result in engine damage that will not be covered by the vehicle warranty. For best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended. The performance gained by using premium fuel is most noticeable in hot weather as well as other conditions, for example when towing a trailer. See Towing (page 272). Do not be concerned if the engine sometimes knocks lightly. However, if the engine knocks heavily while using fuel with the recommended octane rating, contact an authorized dealer to prevent any engine damage.
We recommend Top Tier detergent gasolines, where available to help minimize engine deposits and maintain optimal vehicle and engine performance. For additional information, refer to www.toptiergas.com.

Yoda september/november is GM truck month. If you're not stuck on Ford, you can save up to about $10K on a Chevy/GM truck during Truck month. GM/Chevy trucks have the 10 speed and if you want more power to match Ford, look at the Derringer made by Banks Power.

”Truck Month” is typically to get rid of the last of the past model year trucks. Not likely to happen this year . . . there are very few (if any) past model trucks on the dealers’ lots.

And Rob goes and busts the bubble Thanks Rob

Just kidding - I am going to wait and see - who knows what will happen.

Edit: And on the news tonight GM is shutting down for two weeks at least. Will the rest follow? Maybe the US needs to get thier act together and make chips at home. Ya Think!? Now back to your regularly scheduled unpolitical program - sorry in advance. Delete if necessary

Here is a feature that my next truck will have. SuperCruise. One of the best experiences I've had outside of spending time on the featured circle track at high speed in super cars was to take a CT6 with supercruise through a traffic jamb on my way to Cleveland to a doctors appointment. The car drove itself perfectly.
Now supercruise is coming to trucks for towing and non-towing.
