Look at the attached video right at the 8:30 second mark, under the hood of a 2019 Silverado High Country.

This appears to be the 6.2 due to emblem on hood. 

Notice the oil weight on the cap?  It says 5W-30.

Is GM switching back to this after experimenting with 0W-20 in the K2's ????

Just something interesting I ran across.

Good catch. Yeah maybe they are going back to 5w 30 since maybe the 0w 20 didn’t give any noticeable fuel economy advantages?

Possible.

Could also have something to do with the new Dynamic Skip Fire technology.

or the fact 0-20 burns thru the engines like mine, uses a qt every 6k oil change

I'm going with 5w30 being a more stable oil for the AFM system.  The locking pin can be damaged due to oil aeration.  0w20 I bet wasn't holding up as well when up to temperature as 5w30 does.

A quart out of 8 total in 6000 miles?  That's nothing.  Consumption for the Gen V LT engines is 1 quart (or more) every 2000 miles.

LOL Toyota says it's normal for their engines to burn a quart every 1200 miles. Ford says it's normal for the new 5.2 V8 in the Mustang GT350 to burn up to 1 quart every 500 miles (and that's with 5W-50).

 

1 quart every 6000 miles is pretty good, especially since the lighter 20 weight oils can lose 8-12% just due to volatility.

I’m running Mobile 1 0-20 synthetic and don’t ever use a quart between oil changes. I go 8-9000 miles usually.

Also noted that I didn't see a transmission dip stick.  Hope I just missed it and there is one.

Last oil change I just started running 0w30.  I tried 0w40 and while the oil analysis showed a very happy engine, fuel economy definitely dropped and you could notice the truck feeling more sluggish on cold mornings.  The 6.2 in the vettes have always called for 0w30 or 5w30 and those motors are built the same.  I'm glad to see GM smarten up!

I got 4 free oil changes at the dealer as part of the package when I bought my truck last June. I've used them all up and typically check the oil thru each cycle. I haven't noticed any significant loss of oil between changes & I usually go 12500km or so between changes. The dealer uses a synthetic blend 0w20.

The 8L90 already doesn't use one in the trucks.  Neither does the 10L80/90.  LT and up trim on T1 both use those transmissions.  Both are checked via a check plug in the pan while the engine is running.  I'd imagine the WT, Custom and Custom TB will have a dipstick as they are still using the 6L80.

This seems to be a disappointing trend among all manufacturers. I watched a video on the official procedure for checking the fluid level in an 8L90 and it's a pain.

If you look closer, notice how the airbox is now on the right, the oil dipstick is on the left?

This is a huge change for the 1500 Silverado sierra over past generations.

The "cold air " comes thru the front grille area then to the box and into the engine from the right.

But if someone was to engineer and sell a dipstick retrofit kit,  I'll bet many kits would be sold. This is a real opportunity for some adventurous soul.

I saw one of those videos, too, and it looked like a fairly straightforward bit of engineering to fit something into that check port (where a dipstick tube could go).

 

I am currently driving a 2010 5.7L Tundra and plan to trade it in on 2 019 Silverado or Sierra, soon as they arrive for test drive comparisons.

I hate not being able to check the transmission fluid on the Tundra, and intend to attempt to devise some easy way to check the fluid on the 10-speed transmission behind the 6.2L engine while I wait for that retrofit kit.

 

Hello to all from Bremerton, Washington.

An update.  Not sure if the oil cap deal was an experimental thing, but so far GM has confirmed 0w20 weight for the L84 5.3 and the L87 6.2.  Both engines obviously being the new DFM equipped engines.  Now, it is possible that it may or may not be a typo, but that's what they are showing.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
