  1. Archoil vs. Hot Shot's Secret

    Do you guys have the same ULSD, low cetane fuel in Canada that we do in the US? All the fuel pumps around me are 40 cetane, and they of course are required to be ULSD
  2. Archoil vs. Hot Shot's Secret

    I've never used Stanadyne so I don't know how it compares to Archoil. Glad to hear you've had good experiences with it. I just know that Hot Shot's Secret is a popular additive out there and wanted people to know there's a better option available. That's not to say Hot Shot's is a "bad"...
  3. Archoil vs. Hot Shot's Secret

    Sounds like you used the Stiction Eliminator oil additive for the 6.0? I know those engines have HEUI injector issues that Stiction Eliminator is a good solution to. To answer your question, I don't have any stores nearby, so I order Archoil products online. You can check on their website to...
  4. Archoil vs. Hot Shot's Secret

    Given the poor quality of American diesel fuel and all the emissions equipment that comes on modern diesels, a lot of people talk about and are interested in fuel additives. While fuel additives are generally thought of as snake oil and unnecessary for gas engines, I think most people now agree...
  5. Official EcoDiesel Oil and Filter Recommendations

    My guess? To appease the EPA. My understanding is that full SAPS euro oils are designed to be packed with additives so manufacturers can plausibly claim that use of the oil allows an increase in the intervals one can change the oil at (e.g., 10k miles). This video explains that pretty well...
  6. Official EcoDiesel Oil and Filter Recommendations

    Yeah, it's a bit ridiculous. The constantly changing "recommendations" and "requirements" makes me just not worry about it too much. I've used full SAPS euro oils, a mid SAPS euro oil, and am now running a CK-4 oil that I'll probably stick with so long as UOA results come back good, and I...

    Yeah, pretty sure it's just a repackaged version of Hot Shot's Secret's Gray Diamond 5W-40. Interestingly, Gray Diamond is not listed as meeting Chrysler MS-12991, and in the reviews/comments section of the product, Hot Shot's routinely says it doesn't recommend the oil because it doesn't meet...
  8. Official EcoDiesel Oil and Filter Recommendations

    Here's the 2023 Owner's Manual: https://cdn.dealereprocess.org/cdn/servicemanuals/jeep/2023-gladiator.pdf On page 398, it reads "Equivalent full synthetic SAE 5W-40 engine oil can be used but must be compliant to API SN/SP and ACEA A3/B4 specifications."
  9. Official EcoDiesel Oil and Filter Recommendations

    Here's an odd development. Doc's Diesel just released an "EcoDiesel" specific oil advertised as meeting Chrysler MS-12991. However, my understanding up to this point is that Chrysler MS-12991 oils are full SAPS 5W-40 euro oils, whereas this product is a mid SAPS oil. I'm not aware of any...
  10. EGR Diffuser Tube Cleaning; 3rd Gen EcoDiesel

    Here are some before and after pics of the EGR diffuser tube when it was taken to the shop for a cleaning. 32k miles, mixed highway/city driving (average between 26-27 MPGs per tank), Hot Shots EDT every fill up, and Hot Shots Diesel Extreme every 6k miles. When I did research into buying one...
  11. Ecodiesel Oil Analysis - updated 11/23/23

    I don't blame you. Stays within warranty, and the AMSOIL Full-SAPS and Pennzoil Platinum Euro have proven to be solid oils. One thing you can do to protect your DPF's longevity other than oil choice is use fuel additives that have injector cleaners and cetane boosters. The cleaner and more...

    Candidly, I don't think he knows what he's talking about. His base assumption is that the lower TBN and detergent numbers are signs that FR3 is made of chlorinated paraffins, but he provides no evidence either for the claim that chlorinated paraffins lower TBN and other detergents or the claim...
  13. Ecodiesel Oil Analysis - updated 11/23/23

    If I'm reading the right post, I think OhioTech is making an unsupported assumption that the FR3 is the cause of the lower detergent levels (e.g., phosphorous and zinc). I'm not sure if OhioTech caught this, but the person posting the analysis OhioTech appeared to be commenting on stated that...
  14. Ecodiesel Oil Analysis - updated 11/23/23

    What's weird is that the mid-SAPS oils appear to be outperforming the full-SAPS on reducing wear metals. At least the Amsoil mid-SAPS is. Remains to be seen whether the HSS will too. If it's a choice between replacing the engine and the DPF, obviously you would pick the DPF. But if the...
  15. Official EcoDiesel Oil and Filter Recommendations

    I certainly hope so! Big fan of Project Farm too. One thing I'm hopeful about with the HSS 5W-40 Gray Diamond Euro is the fact that it comes with FR3 already added into it. I'm curious if the HSS oil is optimally "designed" for the FR3 as an additive, so to speak, as compared to another brand...
  16. Ecodiesel Oil Analysis - updated 11/23/23

    Thanks for the feedback! I'm new to oil analyses, so I'm happy to get informed about how to read these things. I've been doing oil changes every 4-5k since I bought the Wrangler new. I'm currently running Hot Shot's Secret 5W-40 Gray Diamond Euro and Stiction Eliminator this oil interval...
  17. Official EcoDiesel Oil and Filter Recommendations

    biodiesel and other posters on various threads looking at oil analysis results for the 3rd Gen EcoDiesel started to notice that Amsoil's Mid-SAPS oil consistently outperformed its Full-SAPS oil and the Pennzoil Platinum Euro 5W-40 (which is also a full-SAPS oil), even though Full-SAPS is the one...

    Definitely can go longer than what I put it through here. 9-10k might be possible with a ton of highway miles, but I personally wouldn't push it that far. From what I understand from other posted oil analysis results, the EcoDiesel tends to change the oil viscosity to 5W-30 after approximately...

    Just got results back for the Amsoil 5W-40 FS Euro. Roughly 21k on the Jeep and 4k on this oil interval. I'm not the best at interpreting these things, but it looks like the Amsoil FS performed pretty solid. Granted, it was only a 4k oil change interval, but with mixed driving of highways and...
  20. Ecodiesel Oil Analysis - updated 11/23/23

    Results after running Amsoil's 5W-40 FS Euro. Roughly 21k miles on the Jeep and 4k miles on this oil interval.
