2019 Sierra and Silverado Motor Oil Weight Change ???

[Sierra Dan]

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?

[Sierra Dan]

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.
