Do you know when the toyota recall happened ? And when those vehicles were made ?


Can you prove me wrong about the dealer tools/training/salary?

You sound like someone that just googled stuff. I promise you that the domestic dealers especially GM pay the most in terms of flat rate anywhere outside of boutique and niche stores. I know this. Its not something I think.

Please prove me wrong..

Here it says GM pays 46% higher than national average. Crazy huh ?


0w-20 has been used in millions upon millions of engines. Millions of 6.2 but now its a problem? Can you prove to me why it is now a problem but wasnt for the millions of other vehicles including 6.2? Please prove me wrong.

You say a lot of BS but cant back up any of it outside of feels.

Do I need to make a YouTube video for you ?
0w20 is used in many applications that were designed for it originally.

Easy to design a bearing system with 0w20 as an assumption. Might want to read about sommerffeld number then get back to me.

I quit being a dealer tech because I was tired of warranty jobs.

Unless you can’t count the total time Toyota took vs gm was order of magnitude shorter.

What's an order of magnitude? Toyota had to recall every vehicle produced up until that point.

You do realize that toyota having an issue like this proves that it can happen to anyone.

You quiting being a dealer tech still doesnt answer the question. Your arguing my points and not providing evidence for your own.

0w 20 is what these engines were designed to use.

Again outsourcing leads to issues. That is the point waaay over your head.

I was a dealer tech for many years. There was no 46% pay increase switching to gm. Period.

These engines were originally designed for 5w30.

What you did and what's reality can both be true.

I was a heavy line tech and could go back ar anytime and still get top pay. My gm training is still valid and active.

If you cant then it says more about you than gm.

6.2 have been using 0w20 for a long long time. Why do you think otherwise ?

I went to a different industry that pays me rock star money… easily paying cash for a 2024 suburban.

I don’t need to explain myself to myth-addicts.

Lmao. I thought you knew something. Sounds like you dont.

Different industry that pays Rockstar money huh? Cool story.

They have been using 0W20 since 2014. Engine was updated with a variable displacement oil pump and increased capacity. It is not the same as the previous gen. Same with the 5.3L which has had no bottom end oiling problems.

Tell us your point. Tell us how afm/dfm is now a problem but wasnt for millions of other vehicles.

Tell is how 0w 20 is now a problem but isnt for millions of other vehicles.

Please tell me. Tell us. We would all love to see your points.
Because the oil isn't the problem. It is improperly machined/cleaned parts. Period. But people want to think that this is 1960 and 20 weight oil is useless. Technology has advanced and I would gladly use todays 0W20 over a 5W30 from 20 years ago.....

It's definitely not about the oil, I drove 700 miles on 0-40 oil after changing the engine, now they filled the oil 0-20 and I am watching the car. Today I will write a little later in the thread where I talked about replacing my engine

Aw man....
I was hoping you had some data to back your outrageous claims. Shucks.
You’re the guy that’s not running on all 8!

If you thinking pushing a crank around with 1-7 cylinders instead of all 8 is progress I have trouble with your intellect.

If 0-40 is right for an LT1 for extra protection then maybe it’s a right for an L87 that uses a lot of the same parts especially in the bottom end like the parts that are failing.

But who cares about a debate when you have the only opinion that matters?

Go ride around in your duramax, this conversation doesn’t affect you or your truck. It’s not what you say or your opinions that bother me it’s your condescending attitude toward me and others on this thread that make me want to vomit. Go get professional help!

So it's a conspiracy?

Do you have data to back your claims? Or just feels ?

I get that many of the less than factual posters get their feelings hurt but all I'm doing is being objective with real data and facts to keep the discussion relevant.

If you would rather it be based on feelings we can do that but we lose the value of discussion.

Here's some reading if you care to enlighten yourself on your misguided logic.



Theres engineering that goes into these systems. It's not 'feels'

Everyone that says otherwise has something to sell you. And hey capitalism is what we are all about. But to think otherwise is foolish.

Our duramax also uses 0w-20 wonder why it doesnt blow up? Or the millions of other engines that use it? Probably a conspiracy

I drove 700 miles on 0-40 oil during the run-in, after which I filled 0-20. It seems that the version that it is necessary to pour oil 0-40 is confirmed, at 0-40 the pressure is high, and at 0-20 it is about twice as low. Do the photos confirm this? :) But no, fans of this movie, :) it's not that simple) after running in, I filled in exactly the same oil that I used to drive 75,000 miles on my previous engine, this is the oil from the Belgian company Wolf 0-20 dexos. Why did I fill in 0-20 anyway? I talked to the Service that made this engine for me. Everyone they made an engine for runs on 0-20 oil, and the mileage on the new engine is already high. So, they poured 0-20 oil on me, I rode a little, warmed up, drove along a small section of the highway at a speed of 70-80 miles per hour, and that's what my oil pressure is 0-20. Wonders. it is about 300 kPa. I'll even post a photo of the oil pressure 0-40 and 0-20 next to it))) at 0-20 it's just a little lower. well, about 300 kPa at 0-20 and maybe 320 kPa at 0-40. My opinion is that either the software has changed and GM has increased the oil pressure, or this is a new modification of the oil pump. But oil has practically no effect on pressure. The pressure on my new engine is clearly higher than on the previous one.

I did extensive motor oil viscosity research in the early 1970s. Many oils that were labelled as a 30 or 40 grade oil were actually a 20 or 30 grade oil right out of the can. They all lost viscosity quickly, probably due to the poor VI improvers of the day and severe fuel dilution in those carbed cars. The resulting running viscosity was often well below the 20 grade.
Recently I ran a 5 grade oil in my Lincoln Black Label XL Navigator. It is unlikely that the oil viscosity is the cause of these issues.
I ran a 20 grade oil in my Enzo that was spec'ed for a 60 grade oil. The wear pattern was less than that of my neighbor's Enzo running the 60 grade oil. Of course these cars were not run on the track, just around town and the highway.
