My thoughts. Pick one but change it more frequently than recommended.

Those are DEXOS D licensed products.  If I owned a 3.0 TD I would run Amsoil DP020 for the performance and cleanliness benefit. Its not licensed but exceeds the Dexos D spec.  My dealer has confirmed Amsoil is warranted. Redline may make a similar product by now and I would look at that too. Why for Amsoil and Redline, testing shows they work exceptionally well and they use higher quality base oils than the licensed list.

Here some info I got from AMSOIL a while back..

While the GM dexos and Dexron specifications plays the important role of setting a minimum-quality standard, it also limits the flexibility needed to create the highest level of protection. AMSOIL uses these standards as an initial benchmark, then moves beyond them to provide motor oil and transmission fluid with superior performance and protection. GM also collects royalties on the license. Subscribing to the program would limit our ability to produce the most innovative products on the market. The additional costs would also require price increases. Rather than paying royalties and passing the cost on to consumers, we back our products with our warranty.. We have ample test data to support our claims.

We agree, the problem is warranty so check with dealer. Amsoil will provide oil related failure warranty but if its questionable have a dealer that will cover your 6.

One of those or the Amsoil Synthetic Diesel 0w20 would do the trick.  Its about time there were a couple more options though with how many of these 3.0s are out there/how long its been out now.

Here is another example how AMSOIL is on top of the game with these new oils.  This in particular the dexos R that the Corvette and Camaro require especially when tracked.

I can only find the Mobil 1 ESP from googling. For the price I'll probably just keep using the AC Delco and Amsoil.

 

Has anyone hooked up a 5 micron bypass oil filter yet?

 

In an email (to me) from amsoil they have no intentions ATM to make a vehicle specific kit for the 3.0 Duramax.

    • Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.

    • Looking for this part for my truck. They don't sell just that one piece and to get it you have to pay over $100 even used for the whole air tube. The piece the hose clamp snaps into that is held on by the screw and nut. If anyone has access to one please let me know.
