yummy...me wants this...where can I buy

I made the mistake of going out of my way to buy "super diesel", and eventually found out "super diesel" is just regular diesel being delivered thru a high speed nozzle ....reducing refuel times.

 

Find out what, if any, regulations apply to fuel where you live. A premium diesel fuel may not even be available where you live precisely because existing regulations require a minimum chemistry that exceeds what is being branded as premium diesel. There is no such thing as premium diesel where I live.

 

Mine was in regen a lot. It was like that since new so I taught it was normal. Then my nox sensor went out completely. Dealer change it and now it regen less than half before.

 

Shorter regen “cycle” reported could also be due to partial regen. 100% to 60% and shutting off truck is considered a regen. Then it won’t regen again until it’s full. Obviously shortening the distance between regens compared to going from 100% to 0%.

 

I used to think that is how regens worked, but that was based upon limited observation. There is something working in the algorithm that departs from that perception. To wit: The screen said I was at 99-percent, so I knew it would start regen once the engine parameters were met. Where I was going left me knowing that this was not going to be a complete regen. I parked the truck with regen down to 60-percent. A couple hours later, I left for home with the regen screen showing. About six miles into the drive, the screen dropped to 55-percent, a mile or so down the road, it was at 50-percent.

So, something different here. My normal observation was a regen down to 20 or 30-percent and it would not continue a regen from there, or at least my driving conditions never allowed that premise to be tested.

I suppose a Ford engineer would have to reveal the secrets to a regen to fully understand how it works. But when you think about it, I think Ford intended this to be a completely passive operation free from operator involvement (excluding commanded regen option) or concern and it's better to just let it do its thing and you do yours.
