Did my firat oil xgange today prior to leaving on a 2500 mile roundtrip towing my 12k 5th wheel. Used Shell Rotella for gas engine. Research looks great on this product. My truck was at 4500 mi. and 40% on o.l.m.

I just traded for a 2020 GMC double cab gas 1 week ago.   In reading thru the owners manual, I was very surprised to find that it says to change oil and filter AFTER the 500 mile break in period and BEFORE towing for the first time.

Ba-da-bing, Bada-boom. 

 

Who would have thought to read the manual.

My wife worked as a customer support member for a software company.

The dumb questions lead to this.

The word in that department was RTFM. Read The F*** Manual.

Just talked to the dealership here in MN. Service Dept. said to change oil every 5,000 miles no matter what the computer says. No need to change oil at 500 for break in period. Use ac delco or mobil 1, with ac delco filter. Take advantage of first oil change and tire rotation from dealer. Available nation wide.

That's interesting, cuz that's not what the online copy says. 

 

Just says:

 

The vehicle does not need an elaborate break-in.

But it will perform better in the long run if you follow these guidelines:

 

. Keep the vehicle speed at 88 km/h (55 mph) or less for the first 805 km (500 mi).

 

. Do not drive at any one constant speed, fast or slow, for the first 805 km (500 mi).
Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.

 

. Avoid making hard stops for the first 322 km (200 mi) or so.

During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement.

Follow this breaking-in guideline every time you get new brake linings.

 

. Do not tow a trailer during break-in. See Trailer Towing pg 292 for the trailer towing capabilities of the vehicle and more information.
Following break-in, engine speed and load can be gradually increased.

 

 

Not a thing about changing the oil after 500 miles...

 

But I'm sure the post was just wanting to get those that don't rtfm excited...

The on-line Operator Manual that I find is part # 84186886C and the OM that physically came with my truck is part # 84186890A.    The page numbers are different but they both say the same thing.

 

Mine has the verbage you quoted above on page 208, whereas the on-line version is at page 204.    ADDITIONALLY on page 287 of my physical manual, at the "driving with a trailer" section, it says:

 

"-Do not tow a trailer during the first 500 mi of vehicle use to prevent damage to the engine, axle, or other parts

-It is recommended to perform the first oil change before heavy towing

-During the first 500 mi of towing, do not drive over 50 mph and do not make starts at full throttle"

 

You will find this exact verbage on page 283 of the on-line version of the document under the "driving with a trailer" section.

 

Not quite sure what "rtfm" means, but I find it good practice to learn all I can about my vehicles.   Sometimes things are not as I assume.

I did not tow the first 500 miles on my 2020 High Country. I did, however, tow several times before the first oil change. It's says that it's "recommended", not required. All that verbiage is skeptical, at best. Many contractors (the bulk of all HD truck buyers) use the trucks hard from day 1, as this is how they make money. Doesn't matter the make, or fuel type, they just work the trucks. Most have no issues and none to public knowledge have had issues related to not doing a proper break-in. Many people have traded trucks while towing or hauling. They simply unhooked from one truck, hooked to the new truck and went on their way. Yes, avoiding these things early on may help, but I've heard of none that said otherwise with any factual data. It's best for one to do what they feel comfortable doing and just enjoy their purchase.

I agree completely that it is not required, and that most people would not do it nor even know about it.   I just mentioned it because I was very surprised to see it in the book, very unusual.

 

This is my 7th gm truck purchased new and this OM is a lot different than the others.    I estimate 30-40% of it was written by the lawyers.

I'm about to change my oil for the first time.  Book says 8 quarts of 5w-30 synthetic.  What brand of oil are you guys running?  Is premium oil worth the extra money?

Napa synthetic is fine or mobil1 or any that meet the requirements.  Dexos required? If so make sure it has the dexos logo

The objective of OEM dealers is to see customers often and increase profits.

I bought my truck on a Tuesday, hooked up a 9000lb trailer on Saturday with only 75 miles on the odometer, and then towed 2000 miles.  No issues and I'm at 10k miles now.  I'm definitely not as crazy about babying the truck as some of you.

A light ramble: 

 

I think something gets lost in threads like this. Everyone expects everyone else to have the same expectations, the same goals and the same motivations as they do. All that does is breed argument. 

 

Some guys are happy to toss a hundred grand at vehicles every three to five years, or sooner.  Nothing past 100 K miles matters to them. Others see the vehicle to purchase as few as possible in a lifetime and see anything under 300 K a failure on their part. A few of us see a million miles at a doable goal. There are people without knowledge and others that just don't care at all. All of these dictate a different maintenance and operation method. There is a right and wrong for a given goal but there isn't a standard for all. 

 

Owners manuals and the maintenance guide in them are just that. Guides. They are not Bibles and yet some put more importance on the manual than they do in a Bible. Funny that. The manufacture lays out a game plan to get you past warranty and out of their hair. No bone soup. If you want better  you have to do better. If you care not, burn the thing. 

 

If you want better your going to have to quit being afraid of the warranty. No one I ever met was denied a claim for doing better service than the manuals plan or using better products than required by that warranty.

      Joke Thread

      By Chuck FB · Posted

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
