I am about to do my first oil change since deleting and tuning my 2016 gmc canyon. Probably gonna open up a can of worms but... What is gonna be the best oil for this truck without the emissions equipment. There are so many options. I do not mind spending a bit more on oil and will do the changes myself. Shaeffers, amsoil, liquid moly, motul, and the list goes on.....

Use anything that isn't Dexos2 rate as it is garbage. As @CleverUserName would probably say, run something that is API CJ-4 or CK-4 approved, which is probably going to be most diesel oils. Shell Rotella T-6 5w40 would be good. I personally use AMSOIL HD Synthetic Diesel 5w40. They offer more protection for your engine, those types of oils. I think this is the 4th time I've done an oil change with AMSOIL and truck runs great on it.

Congrats on a full delete! I wanted to do the same on my 2016, but finding the parts has become problematic.... Thanks EPA!

Once again, I agree with Burgess159, go with Shell Rotella. Thats what the 6.6L big boys use.

I would also get some hot shots secret - stiction eliminator. If you haven't heard of it, you should definitely google it.

What equipment do you need to do delete? I got the delete tune from motorops and just cut the dpf out and relaced with 3" pipe. Motorops sent a full instruction manyal on all sensors that needed to be unplugged.
As far as the oil changes go....
Do you guys think it is worth the $15 extra per change to go with higher end oils like shaeffer and amsoil or save the money with the shell rotella.

@Cheerfulpimp I was looking for the AFe turbo back exhaust, just to use the stock hangers and have it bolt on (Just in case I need to return to stock). I might be willing to cut it out and replace with a 3" straight, as long as I can return to stock if needed and it doesn't sag or rattle.

Did you do the EGR as well?

As for oil, I differ from a lot of folks and still really like the Dexos 2; mobil one's version at least. However, if I was to go with a full delete, shell rotella would be at the top of my list. Just from all the reading I have done on the 6.6 Duramax and Cummings. I like DeBoss Garage on youtube, who has engines that surpassed the 1 million mile mark, and he swears by Rotella and lucas upper cylinder lubricant. I don't have first hand experience but I believe the guy and think its worth considering.

I did not physically do anything with the egr. The delete was just unplugging sensors and flashing the truck with the delete tune. Originally I was go go with new exhaust but figured why not try a straight pipe first? It is a bit louder but I like the sound.
There isnot a chance I would wamt to return it to stock. The truck is much better now. I habe the intructions from motorops for the delete if you want to check it out.

Yeah, that would be perfect if you're willing to share. Sounds like the same result that I was looking for, I just worried about the law changing in my county (currently emission exempt).

I bet its a lot louder, our trucks don't have mufflers, with all of the emissions crap. Would like to hear your truck too, if able.

@Cheerfulpimp I didn't realize you were talking about a complete straight pipe, just assumed you cut the emission out and stuck in a filler pipe. This is exactly the setup I was looking for. I really appreciate the manual, it all looks straight forward and easy (minus having to support the tranny).

Where did you get your pipe? Did it include the stock hangers?

I already have the tune, from a different manufacturer, just curious because I didn't see that exhaust on the motorops website.

The truck is being run as a straight pipe with no muffler. We cut the DPF out and welded about 2.5 ft of 3" pipe in its place. The stock exhaust was reused. In theory... If I wanted to go back to stock I could cut tgat piece out again and put the DPF back

Your question about oil. I wouldn’t go with anything Dexos2 rated because it is very thin and doesn’t have near the protection properties that oils like I mentioned above have. If you ran T6 for example on an emissions compliant engine, you would create a lot of soot that would plug up the DPF much more quickly. Thus why the Dexos2 oils are low ash/ soot oils. I would say if you value your investment then I would go with something better.

Good luck finding the aFe exhaust from the turbo back...unless someone was holding on to one and haven’t sold it yet, you’ll probably never find one. Best bet would be an exhaust shop.

Also, the EGR gets turned off with the proper tune of course. You could get an EGR delete kit then, but again, good luck finding one.

I'm shocked the algorithm did not do a re-direct to the Amsoil site. Shocked.

Running T6 for the last 25K post tuning miles since it is easily available at Wally-World for $22.50 a gallon, and my warranty is out the window anyway. Getting excellent results per the attached Blackstone Labs report on oil that was run for 7K miles.

Not deleted, but running an emissions intact GDE tune that turns off EGR but keeps the DEF system active, and it provides the attached hilarious message in the DIC for my occasional amusement.
