ElCamino and Grumpy Bear shared truth.  Here's the problem, few dealers and techs have time or care to know baseline science about why we are having issues with IC engines. 

 

We are asking a lot from todays engines and a better quality engine oil can go a long way to help. 

 

HOWEVER  I can crush your engine with a small miss that the MIL system won't pick up and add fuels to the engine oil and make significant oil burn off in 500 miles. 

 

Air filter, coils, plugs, ccv/pvc system, injectors, vac leaks, leaking coolant from heat exchangers that NO ONE sees or notices will ruin your engine over time and THE ONLY WAY TO KNOW EARLY is get one of Nicks ISO CERTIFIED ADVANCED OIL ANALYSIS.   Quit guessing and quit trusting people who don't care to help YOU.

While I have never approached things like an engineer would, I have just kept motors in an as new condition and changed the oil and filters. I do applaud the science part but never used it and never had a motor failure. 

Short story, oil wears out so change it. How often is your choice. 

K.I.S.S.

I’m on the other side of the equation. I’m extended.  I never lost an engine. My cost per mile is probably equal or less than the frequent oil change people. My newest vehicle is 8 years old.

You also used a higher quality oil. Amsoil SS. So I get that and your extended history is well documented. Cost per mile is not an issue because I didn't/don't drive the miles you did running a business.

I totally get this and until Dizzy, my experience was identical to yours. (Okay I had a Paseo whose rings gave up but I was to ignorant at the time to understand what what going on and got 300K out of it anyway.)

 

To some extend I still am like this. You will never see me on the extended drain interval list without some heavy lab supervision.  Given it's cost it will never be routine. Spot checks and problem solver tool for me. 

 

Dizzy gave me pause when the OCI's got to under 1K miles and oil still looked like molasses. At some point even cheap oil gets expensive and the changes obnoxious. All that to say we all have holes in our understanding and keep an open mind IF you run across something you can't pigeonhole into something you are familiar with.

 

Think of it as a ring compressor. A tool you don't need more than a few times in your life but ya need it when ya need it.

In retirement it’s more once a year than miles. Except the CRV our trip car. It’s every 8-10K depending how it falls before each trip. Per monitor.

I've had my 2021 Custom a little over a year now. Took her home March 31, 2021.

First oil change was at 500 miles. For the long haul I chose Shell Rotella Gas Truck 5W30.  It was great.....until they discontinued it. I now run Pennzoil Platinum - Made from Natural Gas 5w30. Someone told me long ago, that these engines liked the oil and to check and add if needed. 

Thus far the Pennzoil Platinum has been great.  I use it with a NAPA GOLD Filter. 

What I'm gonna do next is add a catch can I believe.  Also fellas, just be sure your on very level ground when checking your oil level. It really makes a big difference. 

But, I gotta say, this Truck is a real Bull. It's pulls with ease. All that being said, I change my oil & rotate my tires every 5K. 

Anyone else running Pennzoil Platinum?

Also, I think I am correct in assuming Shell Rotella Gas Truck has been discontinued?

At any rate, I believe Pennzoil is under the Shell Umbrella anyways?

Thanks fellas.

Pennzoil Platinum is a great oil I have been using it for a better than a decade in my dodges , my hemis always runs like a top, and yes shell owns pennzoil, 

also lately I have been adding lubegard biotech 15oz just to up the moly in the oil, works great

I changed my oil on my 22 3500hd gasser at 1000 miles and used Pennzoil platinum along with the Fram ultra synthetic filter.  I seem to be getting slightly better mpg than before.  I plan on changing again at 5,000 miles.  So far so good with this oil and I'll probably use it in my car when the time comes.

 

This is a great engine!  It's a lot mellower than the 6.0 gas I used to own.

FWIW:

A little over 5100 miles now.  A bit over 1,400 miles towing heavy (14,600 lbs wide body 5th wheel travel trailer).  Oil life shows 25%.  Lots of mountain pulling with grades up to 8%.  Pulled through Cascade Mountain range, Sierra Nevada foothills & and now up into the rockies, So high loading on engine at low and high rpms. 

Just added the first quart of oil to bring it back between the add and full mark.  I didn't do anything special during break-in (actually used cruise control on long freeway stretches for the first 1,500 miles).  Didn't start towing until truck had that first 1,500 miles (only because I didn't need to).

Thanks for sharing! Curious if the truck alerted you to add oil or did you just check it because of the heavy towing?

Thanks.  Glad the post was helpful. :cheers:

I had been keeping an eye on it about every other fuel stop. 

The truck didn't bring up an alert.  Maybe because it was still right at the bottom of the dipstick.

That engine design should not use a drop of engine oil.  Since it did and is the factory fill you need to change most likely based on your comments and replace with a higher quality oil. Especially towing. Your LOW RPM hard pulls up mountains would have seated the rings really well.  Remember the OLM is an algorithmic calculation with only temp,cycle,fuel usage calculations as sensing. Its a good guess based on GM engine testing, teardown, oil analysis, etc.  Not a direct sensing system.  

 

 Enjoy!

I'll probably send a sample when it's time to change oil.  More for personal input than anything.  I'm not worried about 1qt of use during this period. I'm more interested in the analysis for the future.

    • So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
    • I haven't seen diesel for less than $5.30 anywhere in my area
    • The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".  
    • $3.69 for 87 octane.   $4.24 for Diesel in town.
    • On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?
