I am a business owner with a family and do not live on the internet. This is not the only vehicle in my business. Im going to send you a PM.
Right, I think most of us are aware of what you do. The problem is, and I have mentioned this to you before, is that you come on here, make a thread, post your opinion, seemingly asking for advice, but then don't actually want the advice, you use your threads more as blog posts where feedback is generally ignored. You and I had a similar exchange when we were discussing (well, I was trying to discuss, you were generally ignoring my feedback) your use of Blackstone UOA's to determine shear and fuel dilution and it was impossible to get through to you that Blackstone does not properly measure fuel (they don't use GC) so using their UOA's for that purpose was futile.

You don't have to live on the Internet, you are clearly on it enough to post threads on here. My problem is that you are posting on a forum where feedback is a considerable part of the experience, and you don't engage on that part of it typically. This thread clearly being an exception.

Take this subject. People have been suggesting, many of them fleet mechanics, you use heavier oil. This didn't seem to be an acceptable recommendation to you until you saw an AMSOIL blog post on the subject and then all of a sudden you were willing to give it a whirl. Do you appreciate how frustrating that would be for people, people with experience with this engine in fleet environments like yours, to be giving you that advice and you seemingly ignoring it, instead opting to chase the EVAP solenoid, but then a blog post by AMSOIL is enough to totally change your mind?

Obviously you aren't obligated to listen to any, let alone every recommendation on here, but I do think that if you are having a problem and several mechanics who operate fleets of the same equipment you are having problems with chime-in with advice, it might be prudent to acknowledge and consider their advice, otherwise, there's not much point in creating threads on this board in the first place.

We are generally all just trying to help each other out.
 
Has there ever been any truthful answer to how is the vehicle being discussed is driven? I have lived in the Fleet world where there was always a complaint about a particular make/model using excessive oil. This would be very revealing about the driver’s treatment of that vehicle especially noticeable when 100 other vehicles exactly like the “problem “ vehicle were absolutely fine. These complaints were quickly resolved after our entire fleet was outfitted with live GPS Telematics. Max RPM blasts from every stop as well as excessive cornering and hard stops were flagged and dropped in my email inbox immediately. Needless to say several people lost jobs or experienced significant demotions before everyone learned to drive like they should….
 
Quite honestly if you are telling me you have over 100 2021+ Silverado 1500s, Suburbans, Tahoes, or Yukins with a 5.3 or 6.2 and not one of these is burning not 1 quart of oil...I have to call BS. Everyone out here in the real world and on the internet seems to be having this issue. The issue isnt because of crazy driving.

Simply google "2021 Suburban oil burning". The NHTSA is full of complaints and Im wondering when they will issue a recall.

I will try this 5W30 and will report back with results.

no we probably have 20+ 2021+ silverado’s with the 5.3L and none of them burn 5w-30. the worst trucks we have are two 6.6L L8T trucks that burn 3 quarts throughout the 12k run.
 
You have any

You have any proof of widespread major issues? I’m on my 2nd DFM GM truck and have yet to experience oil consumption issues with a 5.3. I could google every single engine model and find a thread on oil consumption on google. You should consider the advice of REAL WORLD folks who participate on this forum. You know you should be talking to your mechanic instead of us since you value their input so much. I hope you the best in solving your oil consumption issues. Simply loading the parts cannon at the issues and blaming GM with zero proof does no good. I’m willing to bet your not going to tear down the engine with 120% confidence to find a manufacturing defect. For all we know your rings could be stiff from deposits or simply the oil your using does not suit your location/ driving habits.

I wanted to discuss this with you in a private message because having a conversation like this is never a good situational management strategy. Let me put it this way. I rode with a young driver who was getting frustrated how everyone drives on the road and the way they were driving was not matching his expectations. I told him there is nothing you or anyone can do to change the way people drive out on this road. They going to tailgate, cut you off, brake suddenly... The trick is to expect it and plan early to avoid these drivers. The guy who is tailgating just get out of their way and let them pass. Dont get out of the way when they right behind you but when they far away. Whatever happens do not take anything personally and feel like its your mission to change the road. The road is what it is and no one is going to change it. So there is no use to getting upset about it.

If you dont like anyone here or their posting style its best that you dont do things like follow them around or invade threads to which you have no interest. You will not change me, you will not change them and you will not change this internet world. If you dont like me I will not take offense if you simply ignore me or block me. My feelings will not get hurt. However, you are not going to come in and change me with aggressive postings.

The folks who operate this website and myself are like minded. We both operate a business. Im careful with my words here so I do not interfere with whats going on. You trying to control people and threads that you simply dont like is getting in the way of things here. You just said that you have turned off messages because people are sending you vulgarity. Well, if you are telling people what to do and how they should act (versus simply ignoring/blocking them) thats what you can expect. No one enjoys being told what to do.

So look. You cant change the world or tell people what to do and how to do it. What you can do is choose to not be a part of a situation or manage situations to a successful outcome for all involved, but doing what you are doing will not lead to anything good.

Well, you and I don't have an employee/employer relationship. There is no situation to manage, this is a discussion forum, we are having a discussion. I don't see any problem with it happening out here in the open where what we say is visible to everyone.

With all due respect, I've simply made an observation on a certain type of behaviour I've observed from you on this forum over your tenure here, and I'm not alone in making that observation. That said, I'm quite pleased to see you actually making the effort to respond to people in this thread, as that's a (welcome) deviation from past practices.

As I said, I've tried to have productive conversations with you in the past and watched as you drew incorrect conclusions (and was not the only one who noted that) because you didn't understand why the data wasn't useful and weren't willing to acknowledge the reason for that when it was attempted to be explained. I was trying to help you out, but you didn't seem interested in mine, or anybody else's advice. As I said, you've had a tendency to use this forum as a blog in the past, detailing your experiences and acknowledging little if any of the feedback. That's my observation, based on your past threads, this is the first time you've actually made the effort to reply.

It has nothing to do with me liking you or not. I have no reason to dislike you, but I've noticed a pattern of behaviour and I hope, in providing my observation on that, that you choose to address it now that you actually seem to be reading what people are saying to you, myself included.

I'm not trying to control you, I've simply suggested you actually take the advice of the people you seem to be soliciting it from (this forum). Otherwise, I see little value in posting here. I've not provided advice beyond that in this thread because, unlike on the topic of UOA's, my input here is of less value than those with fleet management experience that have been advising you. As I said, everybody here is just trying to help each other, but that's a give and take relationship, which means acknowledging the contributions of others, even if you disagree with them.

I locked down my DM's primarily because of a guy that had 45 usernames on here (that's not an exaggeration) that wanted to "chat" with me all the time in DM's, which I had no interest in doing. He has significant mental health issues, which is why he was banned 45 times.
 
I dont want to get into the whole Ford vs GM thing. Honestly with GM there are a lot of things which go beyond what we talking about here. GM seems to fix some of those things as the model ages but some things remain like lifter issues. The lifter issues is an ongoing issue and one guy here said he never saw one. Well show me than because Ive never known this cylinder deactivation system to be flawless and in fact mine is mostly disabled by a DFM disabler.

I get a kick out of posts like this one. Somehow people think they discovered a situation that has been around for years, then act like it just happened. I posted about high oil consumption in my wifes Chevy equinox about 7 years ago, And what Chevy said what they were going to do about it. They told us what they think the problem is, and were happy to repair the engine. That was, as long as we agreed to pay for an engine rebuild. Her car was using 1 qt of 5w30 wt oil every 750 miles. It didn't matter which brand was used, dexos approved or not. I wasn't about to spend any money to rebuild the engine on a car with less than 50k miles on it, so I figured out my own solution. After trying my own frankenstein concoctions, I found that using 10w40 wt either synthetic, or blended oil gave us better oil mileage. We were using 1 qt every 750 miles, and that increased to 1 qt every 1500 miles just by upping the grade. It might even get better if we went to 20 w 50 wt oil, but I'm happy with the 10w40's performance. The engine now has 95k miles on it as of today, doesn't leak any oil, and there;s no noticeable smoke from the exhaust. The sad thing is, GM made this same engine with the same problem for years, and expected the customer to pay for their crappy engineering.,,,
 
I dont get you.
Yes, that's apparent. But I seem to have inadvertently gotten under your skin, based on the rest of what you wrote. That wasn't my intention. And to be clear, I'm not worked up, in need of taking a breath or any of that projection.
Hey...why dont you stop following me around on here, invading my threads and get out of my life? Im asking nicely.
I'm not following you around. I commented in this thread, with a meme, because you seemed to have a revelation due to the AMSOIL video, to do what people had been telling you to do already, in this thread, and others. I found it amusing, due to your history of not following advice or replying to people on here. I didn't expect you to respond to me, because you generally don't respond to people, so was a bit surprised that you actually did. This is also why I usually avoid posting in your threads (quite the opposite of your accusation).

Again, I'm not the only one who has mentioned this:
I know you prefer to use this site as your sounding board than to take any of our advice, but maybe try some Valvoline Restore and Protect?
Glenda W. said:
Have you started using 5w30 yet like mentioned in other threads???
GlendaW. said:
This all could have been avoided if you listened….
See what I mean?

I'm not the only one who calls it out, but you seem to have hyper-fixated on my reply, I assume because the meme caught your eye and prompted you to actually start responding, and then I wasn't willing to go off to the DM woodshed with you.

Enjoy the rest of your Sunday.

My advice would echo was was mentioned many times already.

Go with a heavier oil 5w30, prefer valvoline Restore and protect which was designed to clean up pistons.
run it for 2-4 ocis and check back.
also install gps monitoring on all vehicles so bad drivers can be replaced if applicable.
