2016 Silverado 1500 first oil change

Not sure but oil plays a big part that wears over time like old age. When's the last time there's been a report of someone dying specifically because of preservatives in their food? Anyone want to argue that organic isn't healthier? Fastest country in the world here but can't face the facts.

Why is it multiple oils all of the same weight can have completely different qualities? Look on YouTube at pour tests. Why is it they have different protection abilities and why you can sometimes hear or feel the difference with different t brands. I could easily tell the difference in engine sounds on my Ecodiesel based on the oil type alone. Something making that happen.

Is mechanic failure really a failure to you? I'd probably consider something a failure long before it actually breaks. Deposit build ups, power loss, vibrations, noises. All can happen before there's a failure. I'm not looking to stop failures I'm looking to keeping something running like it was new.

I just checked WalMart's site and you can get 5qts of full synthetic for as low as $13 and can get a reputable brand with high ware ratings of 100k psi+ for $20. It's absolutely ridiculous that anyone would complain about the cost of it overall. There is factual evidence that all oils are not alike and that longer oil change intervals lead to more issues.

And even the best premium liquid gold super dexos16.385 won't prevent long term wear.

I'm talking oil failure that caused a bearing to fail or scored cylinders because of a lack of lube or lube breakdown.

While maybe dealerships may be going to full syn dexos1, there is still at stack of blend versions on the approved dexos1 list. Even Safety-Kleen has approved listings, and their stuff is all recycled oils. Northland is another company that does the recycled / re-refined oil game, and they are on the dexos1 list also. That oil you are supposedly "wasting" by changing too soon is going right back into the game for another go around. And I would bet there will be blends on the dexos1 list for some time. As for dealerships moving toward full syn, I am more inclined to believe it has more to do with the problems that the turbocharged 1.5L Ecotec has been having and maybe some other special circumstances. So they will just keep the same oil for everything in bulk.

Folks get all tied up in knots about conventional vs blend vs full syn. Really anymore, it is just academic and probably a waste of time except in special circumstances. The marketing folks at the oil companies have really done their job in swaying opinions about oils and convincing people they just have to have something. Just like the off the shelf oil additive folks have really convinced a lot of people they need their stuff. Even conventional oils have come a long way this century. Go onto the Petroleum Quality Institute of America website and scour thru the various test results from different oils they randomly test. Even Pennzoil 10w30 conventional put many full synthetics to shame in both the NOACK rating and the very stout add pack that is in that oil. You want to know how your oils stacks up in terms of base oil quality and the additive package in it, then PQIA is your source site for that info.

And the add pack, which makes up 20% of any oil, has as much to do with how good an oil is as much as what base oil is used. Even the best synthetic base oil needs detergents to keep internals clean and prevent sludge, viscosity modifiers, friction modifiers, extreme pressure modifiers, stuff to control oxidation and acids, and stuff to keep particulates from bonding to each other and keep them in suspension. Put the best synthetic base oil in your engine without any of these components, and you will grenade your engine pretty quickly.... maybe not quite as fast as putting a conventional oil in the engine without these additives, but it will happen nonetheless.

And a conventional can't hold up? Try telling that to the commercial engine builders. Their recommended oil change intervals for their turbocharged diesels are in the 35,000 to 50,000 mile interval arena. And yes, those OEM recommendations are with conventional oils.

But in the end, it is whatever makes one feel good and sleep well at night as far as what brand they use and how often they change it. I change the oil in my pickup annually around July. I put roughly 5000-6000 miles on my pickup in a year. The K.I.S.S principle applies quite well.

Not really fair to compare commercial diesels. If the same amount of oil flows through each engine per hour and you have 4 times the volume it would make sense to have longer intervals. There's diesel fleets that never change oil they just swap out filters.

There is something to be said for quality products. My Jeep grand cherokee was so picky with the ecodiesel it was hard to find oil it would take for the longest. You could take two of equal weights and with that engine you could very easily tell the difference. If you take the exact same engine and put different oils in it you'll hear or feel the difference. So while I agree that oils have come a great distance and you're safe with just about any of them they aren't all equal by any means. I've been doing a lot of reading to find out what will make my engine happy and plan to stick with it. In my 6.2L right now it looks like Quaker State Ultimate Endurance and microgreen filters. Granted the filter is more of a test but they seem very promising based on what I've seen so far.

It is more than an apt comparison. Diesels will put out more particulates in the oil than a gasser ever thought of, for one example. Sure they have more oil sump volume, but not nearly to the level of 10 times the volume to allow them to go up to 10 times the interval. Especially compared to the engine size itself which is typically 3 times the size of these pickup engines. When you take all this into account, those commercial diesels have only a little more oil capacity per liter of engine than a pickup has. A typical Class 8 diesel engine will have about 2.7 quart of oil per liter of engine. A Ecotec engine, about 1.5 quart per liter of engine (5.3L Ecotec). Not on the level nearly the advantage you are implying. Yet, that 15L heavy engine, which is working all out 90% of the time, can go to 7 times the drain interval on a conventional oil. The typical pickup is hardly ever working at 90% it's rated capability.

It is very much true that even oils within the same class, i.e. dexos1, will vary in quality by a considerable degree. There are certain aspects to meet the class the oil blender has to adhere to, but after that they take a lot of liberty in what else they do with the oil to make it good, better, or best.

Curious, what measure are you using to determine that Microgreen filter is very promising? Do you have comparison oil samples or other objective data to determine that? Maybe beta flow measurements at the filter to determine the oil volume per hour difference?

I don't have any personal data with the microgreen I haven't used it yet. I've looked at tear downs and it's made of quality components and have read testimonials and seen several UOAs from others that have been curious. The biggest complaint was cost but I ordered it for $11 shipped so not something I'm going to bicker about cost. Bypasses a low amount of oil, 3-5%, through a 2 micron filter and the post use tear downs I've seen looked like they've performed a very good job. I've spoken to a few guys on BITOG that run them and they've been very pleased. So it looks promising enough to try. They seem to be built pretty solid. One of the guys followed their recommendation of three filters and one oil change at 30k miles. His UOA was very impressive. I'll never be doing that myself but do like the bypass filter of much finer filtering.
