Thinking of going with 0/5w30 ESP. Any opinions on which one? Cold weather is not a concern as I live in Alabama. Both of my other vehicles are using 5w30 ESP
2024 Silverado 3.0 Duramax, 18.8k mi; 5W-30 Amsoil Diesel Oil 5k mi

Neither for your application. If you want a 30 weight oil for your diesel engine here is an option.

Thanks for the reply. Doesn’t have any of the approvals that I see commonly mentioned here. Not questioning you, just trying to learn. Thanks again

Not really, I've been an amsoil user almost exclusively for a few years. I usually buy enough to keep my PC membership free throughout the year.
Mobil 1 makes great oil though. I don't see a need for 0W oil unless you live in a cold region. Less viscosity modifiers means more stable oil at higher temps
You’re looking for a diesel oil, correct? It didn’t appear that you were shopping oils with the correct approvals as your truck specs DexosD oil. Mobil ESP is not Dexos D nor is it a diesel only oil. Therefore, I recommended a 30 weight diesel oil as an alternative.

Correct.
ESP 0w20 is DexosD, but the other grades are not. All the other grades are diesel/gas oils with highly respected approvals that exceed DexosD from my understanding
Yeah I’d run it in a Jetta diesel, BMW diesel, or gas engine; but not a diesel truck. You shouldn’t be looking at MB approvals, and the like, for a diesel pickup. Maybe Ford diesel spec, Cummins diesel spec, GM diesel spec etc.

Just to be clear, this is the 3.0 duramax. Spec’d for 0w20 dexosD
Yes, I am fully aware. I’ve been posting about viscosity options to help the OP mitigate his fuel dilution and the elevated oil temps that the engine incurs. If I owned that truck, with the 3.0 Duramax, I would run a 5w40 such as VPBE, Delvac ESP, Delo 400 XSP, HPL CC CK-4, or AMSOIL Diesel oil. Diesel oil is made to handle higher soot levels and contains the dispersants to do so. This is the point I’m trying to drive home, and it is especially relevant to emissions-intact diesel pickups.

Gotcha, was just making sure. Thanks for the responses and info!!
ETA: considering the ESP is approved for use in small car diesel engines and the 0w20 is for the 3.0, what makes it inferior to the diesel specific oils you mentioned? Again, thanks for your time

You could certainly run the approved ESP 0w20. I wouldn’t, but it’s not my truck
the ESP 0/5w oils hold a plethora of euro approvals. Again, vehicles such as vw and vw diesels, bmw diesels etc. I would also run it in a Toyota Corolla etc. However, I would not run them in a diesel pickup. Please look at the approvals the diesel oils I listed in a previous post hold. If your truck identifies as a Jetta, then by all means run the 0w30 esp.Do any of the oils you’re contemplating hold any of these approvals? These are the approvals for VPBE 5w40. These are diesel truck oils.

Based on the approvals, ESP is a diesel oil. The MB approval is specifically about their diesel engines. Guess I’m not following the difference. No need to respond as I’m sure I’m driving you crazy, lol. Thanks again for the time
Is it approved for the Duramax 6.6, Ford 6.7 or Cummins 6.7? No. Even though the 3.0 is a smaller displacement engine it still makes impressive hp/tq numbers. Are any of the guys posting uoa’s with diesel trucks running ESP 0/5w esp? I’ll save you the search, no. And yes, I’m starting to want to pull my hair out

HPL makes great oil. I use their racing oil in my Camaro's 565
So there are no Dexos D approved oils in a 5w-30 flavor? Just asking as I am interested in a chevy with this engine.

There are, just none that are available in the US. Those running 5w30 and have done a UOA seem to have a lower iron count than others running 0w20. Others who tow have noted a lower oil usage with 5w30. HPL Blends a 5w30 DexosD and have said that it’s about half as volatile as 0w20.
Here’s a screenshot of DexosD 5w30. I believe the last time I looked they were used in Brazil.
+1 on the advice to run a "true" diesel oil, and something other than a 0w20. And this has been my opinion even before GM realized they have an issue with the 6.2L using 0w20 and recommending a 0w40 instead...
If it were my truck, and it's equipped with a diesel engine, it would get a fully synthetic proven HDEO from day 1, in either 5w30 or 5w40 flavor. I'm not trying to eke out the last 0.001mpg and barely scrape by the warranty period before an engine issue; I want 110% protection to all the main bearings, journals, crank and everything else that's rotating while pumping out 450+ lbs-ft of torque from down low in the rev range.
And I'd definitely want the extra protection against fuel dilution that is caused by frequent DPF regens. A good HDEO will give you a better cushion of protection all around, despite not being on the approved Dexos list.
But that's just my opinion...

FWIW, Amsoil now has DexosD listed on their 5w30 diesel oil bottles for which specs it meets or exceeds.
