DIESEL ADDITIVES. Should I do it?

[Tupi77]

Yes, recall has been done. The questions was more given the quality of fuel in North America and if the general experience with additives is good. Although, the manual says it is not necessary, that doesn’t mean it is not good to use additives. The same way most cars these days, the manual says to replace the oil at 10k miles, I still think 5k is a great compromise. Oh boy, I guess I just have opened up a can of worms now regarding oil changes….LOL

I purchased a 2023 Jeep diesel Rubicon this past Saturday and while surfing this forum I see a lot of people recommend using a fuel additive. It will not hurt I am sure but I have logged over 300,000 miles on two different Chevrolet Duramax Diesels and have a VW Jetta diesel approaching 300,000 miles and have never used a drop of fuel additive in my life. So I probably won't use any in this jeep either. Maybe I should start...? Probably won't... as I can of find it a little ridiculous to think engineers would design a fuel pump that require extra lubrication to operate properly. Just my opinion...

I add it an additive about every 10,000 miles. Mostly to keep my injectors clean. If you travel like I do and am buying diesel all over from Sams club to the big diesel stops.

You don't have to but for the few dollars and all the fuel I put in at 10 mpg and you never know if its the bottom of the storage tanks you are sucking in or what.

Thank you all for the guidance. I am in South Orange County (between LA and San Diego). I have not done Biodiesel and probably will only use ULSD diesel number 2 as specified in the manual as main fuel. Heard some horror stories regarding biodiesel. I am thinking in trying the use of AMSOIL and Hotshots and see what works best.

Use a lubricity additive if anything. This is to protect the high pressure fuel pump. Myself and many others use Hotshots EDT or Archoil since both have great reputations in the diesel world.

You can use biodiesel, just make sure it’s from a high volume station and don’t let it sit a long time in the tank. It will warrant more frequent oil changes per the manual. I personally only fill up with B20 when it’s my only option, otherwise I try to find renewable R95-99.

Renewable diesel is fine to use as well, a lot of 76 and Arco stations have it now. It’s chemically indistinguishable from diesel #2, burns cleaner and as a bonus doesn’t stink if you get it on your hands

You didn't have the same HPFP Im guessing... did any of the vehicle's you listed have the same recall as the Gladiator. Im guessing not, that is the reason why most are using it in the Gladiator. You right, typically you shouldn't need them, but I would research the Gladiator HPFP recall before you shut the door.

I had the unique opportunity to discuss this at length with someone who's in the industry at EJS this year (he drives an Ecodiesel JT). He's a firm believer that none of them are worth the money compared to some of the latest renewable fuels that are currently expanding in the market. More specifically 'B99 Clear blows all of the other blends of ULSD and biodiesel away in terms of testing and data'. I guess they're projecting that it will eventually overtake ULSD #1 and #2 as the primary diesel fuel in the US in the next few years based on current production numbers. 'If it does, additives are gonna be a thing of the past for diesel'.

I had no idea what any of this was but after doing some reading, he's got a point. The cetane content alone is night and day better than #2. The beauty of B99 is how it's made vs traditional biodiesel. It's a direct replacement to traditional fossil diesel with cleaner ignition properties. Cleaner burn means better performance, better mpg, less soot, less emissions, and less junk accumulating around the engine. It's very promising stuff and I hope it continues to ramp up to the point that we start seeing it everywhere. He says he runs it all the time since he has direct access to it with his job in his JT and notices better fuel economy and smoother engine performance compared to running standard #2.

Until then, snake oil or not, I'm gonna keep using my hot shots EDT to remove any doubts. The ram ecodiesel forums are under the impression that the new recall CP4 has some kind of roller redesign/coating added to reduce friction. If I can find the post I'll link it here, but based on that info and the fact that I'm still on the original pump, it can't hurt to get a little extra lube running through there. ?‍

I think you're on the right track with the roller redesign, the master diesel mechanic I spoke to mentioned that the reason they are having troubles with the current pump is because of different metals used and one is wearing out the other. He stated using additives in the current pump is the best thing you can do to keep it from grenading until your replacement.

I used Diesel kleen or Seafoam, Im in LA so i go to costco for my diesel and occassionally chevron if i cant get to costco no problems had luckily

I use Costco ecodiesel and have had no problem i usually fill up in la but im in Irvine 2021 Ecodiesel with 65k miles

So totally stupid question… how do you get the additive into the tank? Neither of my funnels will go past the metal stopper.

you need the black funnel that came with the jeep.

Hmm I don’t think I got one with mine. At least I know what I need now. Thank you

*edit* found it, you’re awesome thank you!

I learned a trick from others posting their method on this site. In a pinch it works quite well. Simply turn the pump nozzle upside down fill the additive from the end of the nozzle. From here I either raise it up slightly above my head to allow it to run down into the hose or I keep it turned upside down while inserting it into Jeep's fill neck. Then just simply proceed filling your tank.

Hello all,

Finally was able to get my hands on diesel. Very happy with it. However, given witch hunt in California with anything diesel, I want to keep my diesel running top shape and figure out to start now than later. What have you done regarding additives? Should I do it? Any specific brand preferred than other?

Thank you for all the help and guidance!
