An oil thread has been going on for two days and I’ve completely missed it. Guess that’s what you get for being on vacation.

Only six pages? I’m surprised. Not going to touch this topic, just wanted to pitch in. Carry on, people.

 

Are you saying to go with 5w:30 instead of 0w20 and my 2018 and it would be okay

 

What we’re saying is that it won’t cause any issues specifically due to the oil viscosity, yes. You are more than fine running it.
Hell, there are people running 0W-40 M1 FS in engines that call for 0W-20 and nary an issue.

 

I’d say z um Walt class but ….. 🤦‍♂️

 

Your going back on the class there aren’t ya it’s cool I drive mine like in the movie battleship 😂

 

When you gonna try out the thick stuff?

 

I was I was wrong I admit I made a mistake. Let's talk about oil filters then lol

 

Fram ultra/titanium/endurance
ChampXL
Microgard Select

 

We ran our oils based on bearing clearances at that time which all manufacturers are running very tight bearing clearances no argument just stating what I have learned and if it was wrong it was wrong

 

All other descriptions of you aside, you are persistently consistent.

 

Mega win!

 

And I was just referring to direct injected engines anyway I apologize

 

Where did you get your information that a hot 30 weight is thinner than a cold 0w I'm just curious please let me know

 

From every oil manufacturer that produces a PDS.

For example, let's use Pennzoil Platinum:

0W-20 - https://www.shell-livedocs.com/data/published/en-US/2e937649-ef26-473a-b37c-9dfb01188a94.pdf

Kinematic Viscosity - 40*C: 43.4 cSt


5W-30 - https://www.shell-livedocs.com/data/published/en-US/258dde47-b6ac-4f43-a960-5224b7ee00be.pdf

Kinematic Viscosity - 100*C: 9.8 cSt

So, when "cold" (still 40*C), 0W-20 is 4x thicker than the 5W-30 at hot or operating temperature. If, the 5W-30 being thicker caused problems, as you claim, the 0W-20 would cause problems at any stage of warming up except when fully up to operating temperature.

If you built race engines, as you so claimed, you should have at least a general idea of fluids and that they thicken as they're cold and they thin out as they heat up, for most fluids, especially automotive fluids. Whether it's engine oil, ATF, etc. The fact that you had to ask what someone was talking about in regards to cold oil/warm oil and how they compare tells us almost everything we need to know here.

 

@Spectreniner Your priest diddling you on Sundays after church choir makes you happy is what I got from that

 

Listen bucko, it was worth that wine.

 

Low speed pre ignition has been a problem with any engine even the Corvette engine That's why they're specking in oil without the low speed pre ignition issues it's not just for 4 cylinders never mind let's just drop this and everybody run what they want it's easier that way

Please don't take offense to this but can you read?

Can we all agree to just fill the truck with dexos oil and be happy

 

No, I don't wanna. You're not my priest, you don't diddle me on Sundays after church choir.

 

No call me out that's fine I have no issues with that but there's no way that a 30 weight oil is thinner than a zero weight oil it's impossible it's like a milkshake versus a glass of water it's not possible Read Rat 540s blog all the way through then you can call out whoever you want but you're wrong I hate to tell you there's no way a hot 30 weight is thinner than a zero weight oil. 5w30 flows slower than 0w20

 

Please don't take offense to this but can you read?

 

Tires don't need air what are you talking about. It's all good I'm just going by what I know and what seems to work the best for me so everybody's going to have a different answer me I used to street race and build motors I'm on the side of rap 540 He's doing this for himself by himself with no one paying him and he's posting his results so I tend to believe him a lot more than any other people but that's just me you guys can believe what you want and not starting any shit

 

You don't need to worry, you're not starting anything. You're simply just spreading mis- and incorrect information. People are correcting you so you don't keep spreading said misinformation.

 

I wonder if I started a thread with the question 'How often do I need to change the air in my tires', if I would get as many responses as this one?

 

I use Amsoil signature fully synthetic oil. You don’t have to change it to 12,000-15000 miles thus extending oil change time. It’s medium cost but it last two changes if using a less quality oil. Worth it.

 

In a 2013 you can run what you want. Not the l83 ecotec. If you know what Noak and lspi mean then you would know
Not starting trouble bro. Just trying to make my truck live

To add some gas to this engine( guestion) On older trucks/ cars we would increase the oil viscosity, as it hit 100k mikes or so, going from 10/30 to say 10/40 or something like that. On the eco engine, this technique applies? Just wondering, old school here.

 

Did not know you were an engineer

 

They designed the engine, did you. I use what they recommend. And would not differ from that. They spec it for a reason, no just mileage. You can use 20w 50. It not my motor. My 18 runs like a swiss watch 4000 mile oci with good 0w20

 

So, this is what we call an appeal to authority fallacy argument. The engineers are not designing the vehicle to last forever, they're designing it to get out of the factory warranty period without major issue and cost to the manufacturer.

Secondly, look up the viscosity of 0W-20 and even just a 5W-30. 0W-20 is thicker cold than the 5W-30 is at operating temperature ((to the multitude of 4-6x as thick) (most 0W-20's run in the 50s-60s when cold and most 5W-30's run 9-12s at 100*C operating temp)). If, as you so wrongly claim, that just because a 5W-30 oil was thicker, it would automatically cause AFM lifter issues, the engine would not be able to run when cold or in cold temperatures with a 0W-20 oil. So this completely negates your argument that you have to use 0W-20 or else AFM lifter issues will happen, just based upon viscosity. Now, with that said, there is diminishing returns and eventually you would find a fluid with a thick viscosity that it would cause issues but that simply won't happen with a 5W-30 or even a xW-40 oil.

Your 18 runs like a swiss watch just like someone elses '14-current would run like a swiss watch with 5W-30 or xW-40 oil because they're simply not thick enough to cause issues. Your anecdotal sample size of 1 does nothing in the grand scheme of all things relating to statistics and stastistical analysis of a gigantic group.

In conclusion, I don't really want to call you out being wrong to your face in front of the entire forum but what you're saying is completely and utterly incorrect.

 

Read the Rat 540 blogif you want to learn something Google Rat 540 oil blog. And start reading

 

lol no

 

You can't use an 0w 40 in a 14 and up truck. It's too thick to flow though the lifters and with any piece of debris, pop goes a lifter. Not even 0 w30 for that matter

 

That's not how this works; that's not how any of this works.

 

yeah most vw/audis/porsches have single use drain plugs. It is done this way intentionally, mainly so techs remember to use new crush washers.

 

@Hi-Country Sister's Audi A3 requires the drain plug being changed after every oil change. Strange but true

Also I always change the crush washer on my diesel. Or any crush washer on a drain plug

 

Back in the day, my friend, Nino Consolo, a nice Italian guy from Bay Ridge, Brooklyn, whose family had mafioso connections had a 71 Grand Prix SJ 455 HO. The car ran in the 10s. He never changed the oil or filter. One day the oil filter exploded. He immediately shut it down, installed a new filter, added oil, and went right back to what he was doing that day.
