I will add my eco rating meter was mostly at 95 - 99 % rating for good driving habits
Don't level it or put bigger tires on it. I can't get much if any above 22mpg if I'm driving 75mph or faster. 😭
Yeah keeping her stock.... I am anal about MPGDon't level it or put bigger tires on it. I can't get much if any above 22mpg if I'm driving 75mph or faster. 😭
Every 300 miles regardless of "% DPF Full"I’m not sure what ford’s run time cycle is. I’m still blown away by this truck. It sucks that ford has dropped this engine package.
I have a 2021….. 9 out of 10 regens happen at 497.1 miles exactly. And ALLWAYS last exactly 20 minutes regardless of my drive style. Only time it’s. It 497 is if I interrupt it. At 23k now.@EDank - my rule-of-thumb is 20 miles or 20 minutes to make it thru a complete active regen cycle. As @Milehghcty has noted, the 300 miles is a max mileage limit (for primarily highway driving) but you will regen much more frequently with stop-and-go city style driving, as starts & stops (changes in speed) cause incomplete burnt fuel (otherwise known as soot), which is what ends up filling up you DPF (Diesel Particulate Filter). I am averaging 125-150 miles between regens for my local city/rural driving where you encounter stop lights and turns.
While it is good to know how long it takes to complete a full active regen cycle, the bigger issue for us owners without FORScan or a stand-alone OBD monitor (e.g. Edge Insight CTS3) is WHEN your DPF is 100% Full and whether you are in a position to drive that 20 miles/20 minutes when you hit 100% Full. Active regens will not initiate until you are 100% Full (will not start sooner) AND your engine is at operating temps (EGT11 > 587 F) for active regen to commence. Once you have met these conditions, then you need to drive the 20 miles or 20 minutes w/o shutting engine off (stopping at stop lights will not stop an active regen cycle but putting the transmission into neutral will)
Ford in their infinite wisdom decided to not surface DPF Full % within the IPC, so the average owner has no idea how full their DPF is or if they are in the middle of the active regen. This has been discussed in previous threads, with the Stuck in Regen??? thread being the best thread where we chronologically figured out everything I have stated above. Within the thread, I coined the term "Active regen death spiral" because I found that I was never competing a full active regen cycle with my daily 15-minute commute, leading to my very short oil change intervals (~3500 miles) What I found was that I may have started an active regen cycle during my 15 minute commute (5-10 mins into the commute) but because I didn't drive that 20 minutes to complete the active regen, I ended up with a "partial" regen (think down to 70-75% Full) and then started filling the DPF back up again. In this "death spiral" condition, I estimate I was probably getting 50-60 miles between partial regens.
I only determined all of the above because I started actively monitoring my truck via FORScan to "see" when my DPF was full and when I was in an active regen. In addition you can "program" your truck with FORScan to enable DPF Full % screen in your IPC. FORScan programming allows you to enable/disable things that Ford has programmed into the truck, so they could have exposed DPF Full % to us owners but chose not to. The computer knows when the DPF is full (via differential pressure before and after the DPF) in order to know when to initiate an active regen, so the information is all there and FORScan allows you to see all the signals that the computer has access to.
My personal opinion is that Ford's decision to not expose DPF Full % is going to lead to clogged DPFs for those owners that have city driving style/short commutes and are unaware of anything discussed above. Only time will tell if my suspicions are correct, as I think I have seen only one (1) owner here has reported that they needed to have their DPF replaced. I find it ironic that our trucks have an 8yr/80k Emissions System warranty, but that the Diesel Particulate Filter (DPF) is not covered by that Emissions System warranty but rather by a weak federally-mandated 2yr/24k on "all other Emission System parts" which is superseded by Ford's 3yr/36K Bumper-to-Bumper warranty.
