Hey I just bought a 2019 f350 platinum with 13k miles on it. Not 130k but 13k. Anyway I have 6.0 with like 325k miles on it I use as as welding truck and I’m pretty familiar with the fuel and oil additives that work best for my situation. Is the optilube XPD the preferred fuel additive for the 6.7? Seems like it but I’m just double checking. I have a year of power train warranty left so the optilube will not void this? Should I just stick with the motorcraft? Any suggestions are greatly appreciated. Thank you.

Use what you want, just never tell the stealership that you use any additives whatsoever (unless you say it's motorcraft) while under warranty. They are not going to pay to test the fluids and won't be any wiser to it.

I would still not tell them any additives, motorcraft or other. It's just another reason for them to blame you for manufacturer defects.

So when it comes to “defects” technically wouldn’t Ford have to prove in court that this additive was the root cause of the defect? I’m just throwing this out there. I am wondering. I live in Canada and essentially I have heard you can delete trucks under warranty and Ford will essentially allow this because they have no proof that the delete caused said issue. I almost bought a different truck from Ford dealer that was deleted and was still under an honoured warranty. I asked my mechanic friend and he brought up that Ford has lost court battles because essentially the owner of the deleted truck said “prove it” and Ford could not. So I’m wondering if the fuel additive would kind of fall under the same thing. Again just throwing this out there.

I like your thinking, but are you going to court over a car repair? Few people would say yes to that question on the grounds of time and money (lost wages etc). As for the delete, if you don't want the CEL on your going to be tuning and changing the software could be grounds for refusal unless the dealership did it. I wouldn't want the headache. It is after all, just a vehicle and not worth my efforts. I would simply deny any additives were ever used and keep my fuel receipts to prove what and where my fuel came from. This way there is little that the dealership can say regarding what was put in the vehicle and who should be responsible.

To each their own though. Some are more passionate about vehicles than I am. I use them as intended and enjoy my life with as little stress as possible.

No no I would never do that. I’m just making conversation. It would be in almost any case a waste of time to go to court. I was just wondering. I will do some more research here on additives our fuel is terrible here, generally speaking. It would be nice to have something to help the truck run hopefully better with increased longevity.

"Don't tell the dealer..." total nonsense.

As a Ford diesel tech, I am happy to hear that a customer is regularly using a good fuel additive. There are three things you want in an additive: cetane boost, lubricity enhancer and a water demulsifier that will separate the dispersed water in the fuel allowing the water separator to collect it. DO NOT use alcohol-based EMULSIFIERS. It's the easiest and most pro-active fuel system care you can do. My product of choice? Stanadyne Performance Formula - does more than my big three musts.

I have not heard of anyone using an oil additive (not saying there aren't any) - a high quality oil and filter that meets or exceeds the Ford specification is all you need and there are PLENTY of oil posts throughout all of the diesel forums. In my opinion synthetic is best and do not extend your oil change intervals. I actually like using the oil life maintenance monitor because the algorithm uses engine data like engine hours, idle hours, engine load, temperature and probably more. (they don't tell us exactly what goes into the calculation) The monitor for most trucks will tell you to service the oil around 5,000-7,500 miles, more or less depending on vehicle usage. Otherwise stick to 5,000 or 7,500 intervals.

The maintenance minder is in the instrument cluster. Your level of message center in your Platinum will show a message "Change Engine Oil Soon" and then "Change Engine Oil Now" when it's time. You can also access it to see the percentage of oil life left. (on some trucks it seems) For access to it consult your Owners Guide for instructions on navigating the menus. FYI the base clusters will also have this maintenance minder with the same information... just a little less flashy.

optilube XPD
I have been using a combination of Everyday Diesel Treatment, Archoil, and Stanadyne in my truck since new. I alternate between the three more on a random basis then anything else.

Living in Southern California I don't have to worry much about freezing, but I did make a run to Montana this past winter and started adding the EDT Winter blend while I was on the trip.

I can't say that I notice much difference between the three additives, but I do notice that the regen takes much longer when I skip a couple of tanks.

Yes it is. I personally use dieselkleen, and occasionally motorcraft if I'm at the dealer for something else. A lot of people love the amsoil products. I haven't seen or heard of anyone proving any actual results that are above the others. I just try to stay away from lesser known products that haven't been used by a million other people. I'm not an "early adopter" type. I'd rather let others have the problems while I benefit from their experiences.

I was about to ask your location but then noticed the Canadian flag. The Opti-Lube XPD wouldn't be a bad choice but not really necessary during the warmer months. It is popular, provides lubricity, cetane improvement, demulsifier, a winter additive, and more all in one. I haven't compared from a price point to the Stanadyne performance additive.

In some states here in the US, a product like XPD wouldn't be necessary and could be viewed as a waste of $. For example in this part of California the winter additive is unnecessary. We also don't need a cetane improver, minimum cetane is over 50 at the pump, with some renewable diesel being in the 70+ range. Because of that, if I was looking at Opti-Lube it would be the XL or maybe Summer +. I'm currently using Stanadyne Lubricity formula and have used Diesel Kleen in the past.

You got 325k on your 6.0? I’d say trust your instinct and experience more than anyone’s offered opinion on here! I was a 6.0 guy did all the crap to hope to make it be reliable. Oh my oh my, my 2019 is such a different animal it’s so nice. But from that experience i do use XPD in every tank, and did the S&S gen 2 disaster prevent, as well the fuel filter replace with the real kind. Some folks had plastic filters crack and spray fuel. Those two mods and the 6.7 should last forever without much worry. I also deleted all my environmental crap which helps eliminate failure of those parts but not for everyone. I think the fuel additive is important in 6.7 with cp4 pump, that’s real. More so than for 6.0 even. Google the cp4 stuff.
