Hey everyone, we noticed this question comes up a lot, so we finally put together one master cheat sheet. It covers the exact oil capacity, filter numbers, and drain plug torques for every GM truck and SUV from 2016 through 2026. Bookmark the full guide here so you never have to guess again: https://www.gm-trucks.com/gm-engine-oil-capacity-guide/

I am new to the forum, so I apologize if this question has already been covered. I change the oil myself on my 2018 Silverado 5.3 liter. The manual says it should hold 8 quarts but it only holds 6 quarts. I researched and found out the 2019 holds only 6 quarts. I bought my truck new at the end of the model year. Is it possible it has the 2019 motor?

To error is human. To really screw things up you need a manual.

Absolute: Filter Rating meaning 99.9% of the particles larger than a specified micron rating will be trapped on or within the filter. (Good luck getting that number and it is way larger than you think

The manual is correct, no reason to question it.

 

2018's got 2018's engines. The 5.3's in the T1 trucks run the same engines with minor updates and new names but the oil capacity is still the same.

Yes, That's correct. After 6 quarts it was full according to the dipstick and there is no way that 2 quarts didn't drain out. Very strange!

2018

5.3L / 6.2L hold 8 qts

4.3L (V6) holds 6 qts.  You sure you got a 5.3L???

Btw, oil filler cap on 4.3L will say 5W-30 oil whereas the 5.3L and 6.2L will say 0W-20.

Not the 5.3L and 6.2L, they hold 8 qts.

Some of my biggest screw ups came from over thinking the issue.

K.I.S.S.

Welcome to the site.

 

Never mind the welcome wagon, seems that is what they do to make you feel at home....

 

What is the 8th digit of your VIN?

the 8th digit from the left is C.  (From the right is J)  In response to the earlier replies, the engine is definitely the 5.3 V8

Like others have said, the previous gen L83 is really very similar to the T1 5.3, the main difference being autostart (shuts the engine off and on in traffic) and the ability to disable and engage a finer number of cylinders than just V4 or V8. Other than that, they are very much the same, and both should hold 8 quarts.

 

I can't quote which TSB, but there was one that said 8.5 quarts as stated in the manual for K2 5.3s is a bit too high, but won't hurt anything. 8 quarts for a refill is just fine.

 

I did 8.5 for the time I had my 2014 5.3, and saw no ill effect. I've had my 2017 even longer and only have done 8 quart fills, and that's been fine as well.

 

If you're reading full at 6 quarts, you have something other than a 5.3.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
