How’d the oil look? what did you fill it with?

 

The oil was dirtier than I expected. Dark but clear. No noticeable metal or flakes. I used Penzoil Plantinum Full Synthetic 5w-30.

 

To anyone who sees this thread, I’d recommend running pennzoil full synthetic. Best evaporative properties that will help slow down valve coking, and it’s damn good oil.

 

The Manual states that oil must have the DEXOS symbol to be covered under warranty. I did notice that Pennzoil has the proper rating it just doesn't have the DEXOS symbol.

 

Mine came out pretty black at 700 miles!

 

If we have a metal drain pan do we need a crush washer?

All the 2023 Twins have plastic pans.

Nope, only the early 2023 have plastic. 2023 production switched to metal pans a while back as evidenced by the photos other members have posted showing such.

My 23 AT4 built 5/12 has a metal pan...

 

around 30:30 he talks about the oil pan. Specifically says it’s metal, but yeah I’ve seen them with plastic.

So my question still stands, what’s the crush washer part number?

 

Still looking for the crush washer for a metal pan. Chevy parts dealer was unable to find it. The computer told him even the metal pan uses a rubber o ring. Anyone do an oil change on a metal pan?

 

There likely isn't a crush washer, the drain plug has a reusable O-ring like GM has been using for ages. They look like this.

 

Wild! Well that explains why it has a wide flange on the head. Now to find the part number on that bolt and it’s torque. Something tells me the normal 30 ft lbs for a drain bolt would be bad for that.

 

That style of drain plug on all (most) other GM engines is 18 ft/lbs, and I don't recall ever having had to replace one, or having one leak...it may be the best oil drain plug design ever IMO, so I wouldn't sweat needing to order a spare right away.

 

4/23 trail boss, plastic pan

 

My Z71 was unloaded today. The first thing I did was look underneath while it was still on the transport truck. It was built last week and it did have a metal oil pan.

 

My Canyon AT4 was built in June 2023 and has the metal oil pan.

 

Just changed my 2023 WT oil at 1017 miles. Metal pan. Super easy! Torqued plug to 18 ft/lbs... that seems to be the consensus.

 

How do I reset the oil life?

 

This is covered in the owners manual.

Thank you. Oddly, my truck did not come with an owners manual.

 

There's a digital version in the HMI (radio/infotainment system) or you can download one online. Full printed manuals aren't provided by default anymore to save paper.

 

So glad I read this, it looked like a murder scene under the truck after the Niagara falls started pouring out. Good thing I gave myself a bit of space when pulling out the plug. One turn and 5 ish quarts came out at once. First oil change in this '23 LT! Resetting the oil life status was easier than doing a trip mileage reset, like I did in the old truck.

 

Me too, Sam! Changed my oil for the first time @ 7K a couple of weeks ago and was shocked at how fast the oil came out of the truck. My Trail Boss has the plastic plug / pan.

Anyone have a recommendation for a oil drain pan that can receive 6 quarts of oil in under 15 seconds without covering your driveway in oil? It was just hitting the top of my crappy 15 quart oil drain pan and splashing all over me, the bottom of the truck, and my driveway. I probably managed to capture ~ 3 quarts in the oil pan. 🤦

 

@sork I have an 09 Silverado with the plug shown with the o-ring face seal in an aluminum pan. 130k and 14+ years, never had an issues with it. IMO, best design out there. I just put it in, turn until it stops solid and done. Never looked up the official torque.
@DieselDrax Japanese cars used crush washers into the later 2010's. I have a '15 Subaru that uses them. I have also seen Honda's use them. I don't know if they still are, but it wouldn't surprise me. To me, they're kind of a PITA.

 

I wonder if a Fumitomo drain valve would help? Maybe provide a bit of flow control. Their website claims to have 4 options that fit. I've never used one, but I've seen a lot of folks on the Subaru Forester site swear by them.

I’ve used Fumoto Oil Drain valves on my previous vehicles and it makes oil draining a breeze.

However, the Fumoto website references a 2.5L four, so something isn’t quite right

 

Sadly, no for the plastic pans. The plug is a much larger quarter-turn type, more similar to the oil fill cap. Fumitomo should have a version for the later trucks with aluminum pans tho.

That's the base engine in previous gen.

 

I have noticed on several accessories some places just changed the year without changing the product. This was especially true on tonneau covers and to some extent running boards.

It’ll cost you!

 

Can anyone confirm what the 2023 Colorado oil plug bolt size is (metal pan edition) or had the chance to measure theirs to confirm?

During my first oil change at 1k just to dump the "break in oil" (not here for that debate as I know that's always heavily debated),
I Ordered a couple magnetic tipped replacement plugs (standard GM M12 x 1.75) but those were much larger than the stock bolt so I ended up reusing the stock bolt buuut would like to swap on the next change with a magnetic one.

Was very surprised at the size difference and the interweb doesn't seem to clarify except offering the plastic twist bolt for plastic pan versions. Even simply googling the 2.7L part numbers is still end up finding the M12 x 1.75 spec.

 

I’m trying to find that out too. The same GM part number is used in the Caddy CT5 V6. RockAuto doesn’t list the plug, but the oil pan info for that Caddy says the drain thread size is M10x1.5. That also tracks with your finding that the M12 is much larger. TBD.

So, I'm one of the crew that believes your should change out your first oil at 1,000 miles or thereabouts. Today my truck hit 1,010 and I changed out the oil that has all the break-in lubes from engine assembly, etc. I'm not posting this to debate when to first change oil in a new truck. I'm here to report on how simple it was.

First of all my '23 Trailboss is high enough that I did not have to put the truck on ramps. I crawled under just behind the passenger front tire. The oil filer (AC Delco PF66) and plastic oil drain plug are right next to each other! I heard about how when you remove the plug from the new plastic pans the oil comes pouring out. I used a 3/8 socket and it fit right into the square, recessed area in the plastic plug. It takes about 1/2 of one turn and out comes the plug and its like Niagra Falls with the oil. It drained 6 quarts in about 15 seconds flat.

I also heard others say the factory filters are screwed on very tight. Well I used an oil filter "cap-style" wrench from Harbor Freight with a 3/8" x 6" long extension. My filter was on tight but not as tight as others have led me to believe. It came off without any stuggle, cheater-bars on my rachet handle etc. Not problemo! It drains about a quart of oil from both the filter and housing above it.

I filled the new filter with oil and then reinstalled it hand tight and then about a 1/2 turn with the oil filter wrench. I put the plastic plug back in the plastic pan and gave it a 1/2 turn so that it bottomed out on the pan. DO NOT FORCE IT PAST WHERE IT STOPS. I added the remainder of the 6 quarts of 5w-30 fully synthetic oil and I was done in about 10 minutes. EASY PEASY! No ramps, easy access to everything, and something where you can spend about $30 bucks for both oil and new filter. Cheap insurance on new truck engine! Oh, and the PF66 filters were easily found at my local Autozone and ran about $8.17 each with a $1.00 rebate!!

Hey man,

quick question for you. I just did my first oil change recently at 4800 miles, after adding the 6qts of oil and checking dipstick it looks like my oil is above the cross-hatched section. Were you getting a similar reading? This was with a filter change too obviously.

 

Overfilling is not good. You might consider buying a Pela oil extractor. The hose goes down the dip stick then you vacuum some oil out. No need to remove the drain plug.

I know... It's crazy how fast the oil comes out!
My next oil change I put a vacuum cleaner hose sucking on the oil filler tube so when I pulled the drain plug nothing came out. Then when I turned off the vacuum cleaner the oil came out. Worked like a charm.
