3.0L Duramax Sierra Oil Change - I did NOT use DEXOS D oil!!!

[@CitizenOfBabylon]

0w-20 is so Chevy can please the EPA fuel economy requirements. That's why these engines get blow by. After break-in, I use 5w-30, no issues at all. I did the same with my two Toyotas, no issues.

[@canamxmr4760]

Demon works actually posted the clearances for the engine. Very tight. I think 30W would work in a pinch but looks like sticking to a 20W is ideal.

[@pomz3604]

If you are still under GM warranty it would not be wise to deviate from the the Dexos D spec. If you have an issue with your engine, GM is going to request all your receipts and documentation for oil changes and they could technically deny your claim, regardless of whether the oil caused the issue or not. Rear main seal blowing out is a common issue with the Baby Max.

[@adambrown6930]

Wix filters and Amsoil 0W-20 since brand new and have almost 50k miles on it. No issues at all.

I'm enjoying your videos as someone who is looking at getting a Duramax Elevation. Thank you for sharing so much of the ownership experience.

You bet! Thanks for watching and let me know if you have any questions!

[@drkbrent8976]

“DexosD” was developed by GM for licensing/branding marketing. Oil companies pay GM big bucks to stick that spec on their bottle. Currently, Ow-20 is the weight (5w-30 is on the way). GM recommends this arctic oil to meet CAFE standards. Any ACEA C3/C5 or VW 507/509 oils are just fine. Many other brands are fine too…even those that choose not to pay GM to license the brand. Your truck won’t notice the difference with the Castrol you used. 👍

@@johndsmith7785 because DEXOS D isn't an artic oil. It has a HT/HS of 2.9 or greater which means it's actually "thicker" than many 30 grades. The Castrol used here isn't remotely close to what is specified and DEXOS isn't just a license it's an actual performance specification.

[@dlg5485]

I'm looking to get a Silverado RST Duramax next year and I will definitely be doing my own maint because the dealership charges way too much and usually screws things up anyway. Here's a tip... don't rush taking the oil filter off. Just loosen it a little until it starts to drain and let it drain slowly, then you can remove it without oil running down your arm.

[@pheyup33]

Just did my first oil change on my 3.0 Duramax, went with Amsoil

[@anthonytetreau522]

The oil pump is a variable displacement pump, the pressure is regulated by the ECU, regardless of the weight of the oil.

[@barronmclemore7511]

That oil (Dexos 2 5w-30 not to be confused with Dexos 1 gen 2 or 3) is also spec’d in the Cruze diesel, equinox and terrain diesel, Colorado and canyon diesel, all with the same emission systems / after treatment systems. Currently we’re running the 0-20 Dexos D in ours, but we have fleet pricing through the dealer and it is basically the same price for us as Dexos 2.

[@pomz3604]

My Chevy dealer in here in Canada charges $209 + tax for an oil & filter change on the Baby Max, more than they charge for the big Duramax.

[@jimm2442]

I believe that the oil you used will be fine. The only thing that concerns me is that the oil pump on the Duramax 3.0 is driven by a belt and that belt may be sensitive to the oil type. Amazon, as you probably know has everything you needed in stock the Dexos D oil and the PF66. While that truck is under warranty I personally would only use OEM, but that's me.

[@BanditDavesToyChest]

At the time when this was filmed several months back oil was weeks to over a month wait across the board. I fully admit I waited too long for a change but was able to come up with the above combo and have already changed it since because I drive so much. Zero issues.

[@clhbrickhouse]

Interesting note is that the pf 66 oil filter has no bypass valve. Variable displacement oil pump so I would stick with 0w20. I get my dexosd from rock auto.

[@BanditDavesToyChest]

Point me to this literature, please. From what I can tell the PF66 has the standard poppet style relief valve like the rest.

[@cristiana.8241]

all filters should have an bi-pass valve or they would blow up when dirty or clogged.

[@kenc2386]

My recommendation is to change the oil more often, like 5,000 miles instead of the factory 10k recommendation. With emissions era diesels, everything will be more expensive. The 0w20 vs 5w30 is for cafe rules. They can claim 1 mpg better with thin oil and another mpg with the 10 speed transmission.

Wouldn’t that void your warranty in case of an issue ?

The dexos2 I used is the same oil GM recommends for the baby Duramax in the Colorado. Pound for pound it translates similarly to the dexosD. I’ve had several thousand miles since my video with zero problems. Will 100% do again if needed.

[@slimboywalkin14]

Just make sure when you change it or do something similar next time to atleast get dexos 2 not dexos 1gen2 Your totally fine but generally you want to atleast top Off with a diesel rated oil. It’s low of sulfated ash vs regular dexos isnt and would overtime damage the emmision system

So Dave what does the manual say are the specs on the oil? There should be a lot of oils that should meet the specs. Also because of the emissions don’t wait to change so late. Oil is cheep, 50 to 75%on your oil change meter would be good.

I also live in the northwoods of Wisconsin so it also see's sub zero temps on a regular basis during the winter. Still running like a champ! Diesel oil is ALWAYS much darker than gas engines. Why the hell are you using the wrong oil weight? There's zero reason for running anything other than 0-20 ALL YEAR.

Your oil will be jet black and that is completely normal for a diesel injure. And it’s not to do with the fuel it is to do with your EGR. Your EGR takes exhaust gases and recirculates it back in the engine. The set in the exhaust is what makes your oil black.

I would rather go three thousand miles with any type of oil than go 15,000 miles with a gm approved, dexos d, lgbtq oil. When oil gets black it doesn’t lubricator as well. Then pieces of metal get in the oil and cycle through your engine doing damage. I wouldn’t ever go over 5k miles before an oil change regardless of % on dash.
