This has been discussed in length on this forum and plenty of information can be found elsewhere online as well. R is not B, and what is called Renewable diesel is not Biodiesel. Different products, different standards.

 

Most everything I'm seeing in Commiefornia is R99 now. Even at the big rig pumps at truck stops.

 

Yeah I see a lot of R99 and it seems like the Loves have B20.

The station I get it from here in Greenfield has some serious labeling issues though. The buttons say Diesel #2 with the R99 label attached to the pump near the nozzle. The pumps for the big trucks state R95. They have recently updated some stuff at the station and now the R99 stickers are gone and they have put green ULSD 15ppm stickers in their place. The pumps for the big trucks still state R95.

So I asked the clerk inside. He had no idea but could tell me that there was only 1 holding tank for diesel… this only made things more confusing given the stickers on the pumps all say different things… it just can’t be…

A couple of weeks ago I drove by and saw the tanks being filled so I stopped and asked the guy filling the tanks. He said he only ever put R99 in the underground tank… so that cleared it up…

It’s bad enough the labeling is so confusing, but I’d think they would legally have to be marked correctly? There is a 76 station in town that is marked much more clearer (R99), but I get all my discounts with Shell…

 

I love the R99 - I noticed overall better fuel economy with it plus hotshots edt- I do believe it really improves miles between re gens when using both

 

Maybe it's the reduced regens contributing to an increase in fuel economy. R99 is known to decrease fuel economy slightly. A loss of MPG's was the first, and only real difference I've experienced when using it. In my use, regen frequency has bee pretty much the same. I also use hotshot edt, and again, notice no difference in regen frequency. Maybe it's because my use is mostly in town, not towing.

 

Am I missing something on the regen frequency? I thought the truck will regen at 495ish miles no matter what the actual soot load is? I have the Banks iDash Pro and can watch the soot load go down from passive regens while towing and yet the truck’s percentage gauge continues to count upward until it hits Full at around 495 miles even if the the iDash says the soot load is around 15-20%. It will then active regen.

 

I agree, I have noticed a decrease in fuel economy since using R99 for the last 10 months. Also, due to the lower specific gravity of the R99 vs D2, the lie-o-meter seems to be higher every time by at least 1 mpg. I have hand calculated the actual mpg's every time I fill up since I got the truck back in September, 2021.

As for additives, I have been a long time Hot Shot's EDT user (except for that 5k mile Archoil AR6500 trial... which was worse, I'd stick to Hot Shots!) however, I recently switched to OptiLube XL since I am exclusively using R99. Renewable diesel has a 70+ cetane rating, so there is no need to boost cetane levels, and it is a cleaner burning fuel, so a lot of the extra additives that clean the fuel system shouldn't be needed. However, Renewable does lack in lubricity, so lubrication is needed! Hot Shots will work fine for this, but it is also needlessly boosting the cetane level (possibly too high as there is such a thing) and all the extra cleaners aren't necessarily needed. This is where the XL comes in... it excels beyond Hot Shot's (and likely any other additive) for lubrication, and still adds a tiny bump to cetane, as well as cleaners. I figure this the XL is a great fit for those of us using Renewable exclusively....


As for regen intervals, I don't really see any difference in the intervals on renewable either, however, I also use a FBC additive in every tank of fuel, so that's probably why.

Ongrade, that is interesting that during a passive regen you can watch the soot load decrease on the iDash, but not the truck. What MY is your truck? And are you watching the DPFSL PID or the DPFRG PID on the iDash? My 22 will passively regen anytime my camper is hooked up, and both, the DPFSL PID on the iDash, and the DPF% reading on the truck will both fall. However, the DPFRG on the iDash will continue to count up since it is simply counting up to the mileage trigger.

It's also worth noting that I have OCR activated on my truck, and I keep the Active Regen option checked off. Whenever the trucks display hit 95% I will plan to take a longer drive and turn active regen back on and let the regen complete and turn back off before I finish that drive. Then I turn off active regen again and go back to watching the DPF% on the trucks display climb until it is time to complete another regen.

Next Saturday we are leaving for a 2500+ mile trip with our camper. I will leave my active regen turned off the entire time since the truck will never build enough soot to need an active regen thanks to the passive regen.

 

Truck is a 2019, I’m watching DPFSL on the iDash and watch the soot load drop while towing. Also have all the EGT gauges on the iDash and see the passive regen happen when the EGT gets over 575 degrees. Last month I ran from CA to ID towing a large trailer and my EGT never got below 600, even downhill because of the frontal area of the trailer. 550 miles each way and the truck did 3 regens. I have OCR activated and it didn’t matter, it hit full at 495 miles and told me to regen. When it hit the mileage trigger the iDash was showing 15-20%. That’s what has me wondering, I see posts from people who never hit active regen when towing and yet my truck will regen at 495 miles no matter what. I was tempted to ignore the regen now message and see what happens but don’t want to wind up screwed and taking it to the dealer to reset it and get out of limp mode.

 

It does seem like each of the model changes have their own characteristics... so the 17-19's likely act slightly different then the 20-22's...

Either way, if you have OCR activated you should have the ability to then turn the active regen on or off in the advanced settings on your truck. If you have active regen turned off, it will not go into an active regen, even when you hit the mileage target, or even if you hit the soot load target that Ford sets (indicated by "100%" in the trucks DPF% screen). If you do not turn the active regen off in the trucks setting menu, then it is turned on, and regardless of the soot load, it will always go into an active regen at the mileage trigger.

It seems like you are watching the iDash for your information. Are you watching the DPF% screen on your truck too? Regardless of what the iDash says, the truck does not care. What you are seeing on the iDash will have no bearing on what your truck does. The is why it is a good idea to also watch your DPF% screen on your truck too.

But if you want your truck to never go into an active regen you must turn active regen off in the trucks advanced menu.

If you are getting the "Regen Now" message on the trucks screen, then that does mean that the soot load has hit the preset target that Ford has set, and yes, you should do it. Don't ignore it. However, if your truck is truly passively regening, then you shouldn't see that message as a passive regen will slowly burn the soot out. For example, when I hook my truck up to my camper next weekend I will be around 50% DPF% according to my trucks screen. But, I know that as soon as I leave, that number will begin dropping, soon reaching 0% on both my trucks DPF% screen, as well as the DPFSL on the iDash. (The DPFRG PID on the iDash will hit 100% and stay there as it is just a mileage trigger.) I also know that for the next 2500 miles while towing, it will never accumulate any amount of measurable soot, and both screens will remain at 0%. And since I have active regen turned off, my truck will never go into an active regen during this time.

 

I watch the truck’s screen and it will show the soot load increasing even when towing. But the iDash shows it dropping when towing. The regen now message appears at the mileage trigger with the active regen turned off. I can’t believe I’m still accumulating soot towing heavy enough that my mileage is down around 9 mpg and my EGT at the EGR sensor is 1200+

 

That's interesting, and definitely different from mine. Maybe you are accumulating more soot than what you are passively burning off? It sounds like leaving active regen turned on is the best option for you, that way when it's time the truck will go ahead and just do it. Then again, having it off and waiting for the message to appear will at least give you an indication when it's time to do a regen and you can plan to drive til finished rather than shutting it off in the middle of it.
