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.

:idiot:

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.

I don't see a 500 mile break in requirement in owners manual. It does say not to tow in firat 500 mi.

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.

Hagar68 · April 6, 2020

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.
