So, I just bought a brand new 2020 Sierra SLT with the 3.0 Duramax.  I drove it home last night from the dealership.  It had around 200 miles on it when I picked it up.  I drove it all day today and put about 100 more miles.  The odo shows 316 miles.  I parked it on my concrete garage pad and went into my garage and saw fresh oil on the garage floor where it had been parked.  I looked under the truck and saw it dripping oil onto the garage pad.  Then I saw another spot where I parked it yesterday for a short time, again more oil.  I look under it and saw oil coming from somewhere above the oil pan but could not pin point the area of the leak.  I then checked the oil and there was only a small oil mark at the very tip of the dipstick.  I have to assume it's been leaking since it was built.  There were no warning lights and it seems to be running fine.  I did notice that the engine oild monitor showed only 75% life left?  The dealership was already closed for the day.  Any suggestions?  I dont think I want a brand new truck that's been run dry of oil.  Should I ask for a new truck or should I have this repaired and take the chance of future issues?

It still has oil in and so it hasn't been run out of oil yet.

 

Stop driving and call the dealership in the morning. They should come and pick it up on a tow truck because further driving could harm it.

 

They won't just give you a new truck, things don't work like that. You don't even know what's wrong yet so why would you question that there is a huge problem already?

I just dropped a ton of money on a brand new truck....one that should be free of major oil leaks. I'm really upset. Would you want a brand new truck that has this issue?

No, nobody wants a truck to leak oil.

 

You still have to look at it from was it is in real life. The truck hasn't blown up and it's not crashed, so why would a dealership just turn around and give you a new vehicle??

 

It could be as simple as a loose oil filter but without them looking at it, we don't know. I've dealt with more oil leaks on cars than I can remember when I worked in a shop. Small leaks spread oil around like crazy. Clean up is very simple with the right products, if done right you would never know something happened.

Mine had an oil leak, it started about 4900 miles after my first oil change so was about to get a oil change anyway, they said that somehow the filter came loose. Not sure if it was a problem with the filter or the truck, but you might check that first.

I am going to let them check it over.  Its definately not the oil filter or the drain plug.  The leak is somewhere above the oil pan.  I could not see where it's coming from.  It's just leaking a lot of oil.  I will update when they tell me what's wrong.  It's just incredibly frustrating to have a new truck with 300 miles on it and having a problem like this.

You want guarantees.  There are none.  That is why there is warranty service.  ****** happens during manufacturing.  Or for all we know someone crawled under there while it was parked somewhere and loosened something in hopes it would piss you off and blame GM.  (Not likely what happened though)  Just because you encounter an issue doesn't mean you automatically get a new vehicle.  NO matter how much you paid for the vehicle.  Get it fixed, ask them to check for engine damage, get it documented I doubt there is any damage if you were still registering oil on the dipstick, even a little, its when the oil doesn't register on the dip stick that it gets low enough to set the oil light and by that time you do have damage in many cases. 
Just let them fix the issue, and stop worrying about it.  Don't make a big deal out of something until you know what happened.

If there is no low oil indicator light popping up on the dash, drive it until the engine seizes up.  Then you are guaranteed a new engine.

Let them check it out. I had two vehicles use oil from new and had a normal life. I realize a leak is different and can be fixed. Where the oil is on the stick depends on when you check it. Just being on the stick you’re probably fine.

I wouldn't be a happy camper either.

But the reality is they will fix it.

Depending on what is wrong it's your decision where to go from there.

Don't expect a new truck.

I highly doubt there is any engine damage.

It's not as bad as I thought.  I got the truck towed to the dealer and had them drain the oil with me present so I could see how much it had left in it.  It still had about 5 quarts (it takes 7).  The oil was clean.  The are now figuring out where the leak is.  I will update when they find out.

Turns out it's a seal that goes from the intercooler to the engine.  The seal isnon order...should be up and running Monday.  My dealer has been great!

There is no oil going to the intercooler. Just 2 coolant lines and the intake air.c53665137582ba796a2724d5e57d992e.jpg86b39ffa290e295a46c094880ce447f4.jpg87f4ec6b338c73f65e8c47f98ec31959.jpg

      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

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
