My truck came with an owners manual and a quick start guide but neither discusses the oil change intervals, capacity or oil weight to use (aside from what's on the oil cap.) Am I missing a manual or are we suppose to just wing-it?

There's a lot of jumping around in the manual to find it all. If you haven't already, find and download the electronic version of the manual as it makes chasing this sort of info down a bit easier.

 

Oil need to be dexos1, full syn, and "appropriate viscosity" for the engine.

SAE 0W-20 for the V8 engines and 5W-30 for the L4.

V8's use 8 quarts, the L4 uses 6 quarts.

The truck is intended to "tell you" when to change it based on monitoring different data points of the truck in operation. You'll need to change the oil annually no matter the distance you drive. Otherwise, you might get anywhere from around 3k or so to 8k or more depending on the exact operating conditions. Heavy towing around town, short distances, high outside temps - short mileage. Cruising across the country on flat highway in moderate temps at 65MPH might net more like 8k miles or so.

 

You can still follow the 3k / 3 month thing if you want, but you likely won't need to do it that often because you'll be running full syn.

Glove box manual is not complete. It only covers a few things on operation. Full one is available online at MyChevrolet.com. Ran into this on my '23.

Watch for Dexos 1 Gen 3. Theres some older Gen 2 still out there. I still have some left from a previous buy, its fine for use in the gas truck engines. 

 

Gen2 has been "sunsetted" by GM and they have moved to Gen3. I don't know that there's any ACTUAL difference in the spec, but there's almost certainly no MEANINGFUL difference in the spec. I have Gen2 stuff that will be going into the Camaro in the spring and I have ZERO reservations about using it there or in the truck until it runs out.

Gen2 Verses Gen3

I love this chart. It makes me laugh. Minimums on deposits and sludge? How about boutique zero! 😱

Half a percent in NOAK. Any decent boutique is half that. 😏

Wear is TBD????? :idiot:

 

Standard aside the 'in practice' results in Ash reduction are a staggering 0.08% reduction. Really? :rollin:

 

Biggest news for this standard is LSPI which means lower Ca and more Mg and overall lower TBN.

To be blunt, dexos certifications are marketing bullshit. They are a revenue generator for GM and nothing more.

The engineers give the formulas to corporate operations (aka bean counters) and the formula is put out for private label bidding.  Guess who always wins that bid. The LOWEST bidder. Then guess what the lowest bidder does…they try to maximize their profit by staying on the bottom end of the specs. It’s no different than any other private label product in any other industry. 

The oem companies have a profit center in their service departments and getting their equipment back in for service is just part of their plan.

That’s just the way it works.

Huh? What does "lowest bidder" have to do with this?

 

GM creates a BS spec then requires oil companies to pay to have their oil "certified" as meeting that spec so the oil company is allowed to add the label to their product. This generates revenue for GM -AND- it protects them financially by providing an "out" for engine failures (if they can prove you didn't run a certified oil). GM purposefully designed the program so that the certifications are only good for a certain amount of time before they "expire." Leading up to that time, they change the spec in no meaningful way then require the oil companies to pay again to carry the "new" badge.

 

It's all a bunch of crap meant to confuse the consumer, generate revenue for GM, and force the oil companies to keep opening their wallet lest they find their oil products undesirable by the consumer in the aftermarket. Because GM is in bed with Mobil1, you will ALWAYS see their oil products achieve a certification first in any of the categories that GM dreams up.

Close. Even if you use a non-Dexos oil they still have to prove that oil lead directly to the failure.

Maybe, maybe not. It depends on whether you have science on your side (meaning that you can show that the oil that you DID use met the specs or exceeded them) and how deep your pockets are. Once they deny a warranty claim, you basically have to sue them in court.

Magnuson-Moss Warranty Act

The burden of proof is entirely on them. You don't have to show squat. More times than not a letter from you lawyer will get them off their suborn stance. Lawyer won't take the case if he can't win it and they will pay your fee when they lose. But yes, have your ducks in a row. Meets or exceeds will be a sticking point if you decide to try this with some bottom shelf swill. You will get no sympathy from them, the law or anyone else if you 'cheap' and "cheat". 

 

About once a month this Magnuson-Moss pot boils over. It is getting old enough that this is the last time I reply to it. 

 

You have a nice day.

I'm fully aware. But GM also knows full well that they will "win by default" in most cases simply by starting out by denying the claim. The consumer walks away from it more often than not at that point.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
