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.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
