0-20 oil too thin?

My goal is to get 300k trouble free miles out this vehicles whether I, or a family member puts those miles there. But most likely it’ll be the latter cause I see myself in a new Lexus or TOYOTA when the urge to change kicks me again.

If I should get more than my stated mileage goal, I’ll consider it a freebie.

How I get there is the issue, and for me the plan is to follow the factory recommended oil (full synthetic) and viscosity (0W-20) because they have torture tested these engines to undergo far worst circumstances then I will ever put it thru and they have determined this is the best WTG.



Hope that helps
Cheers!

 

Close, but not quite.

There is, in fact, a LOT of misunderstanding of the "first part" of the rating (wikipedia is wrong here). The xW part.
A 0w oil does *not* attempt to emulate an SAE-0 at some specific low temperature. In fact, that number specifies the *temperature* at which the oil will flow.

0W: -30 deg C
5W: -25 deg C
10W: -20 deg C
15W: -15 deg C
20W: -10 deg C

The second part of the spec is much easier to understand. It is the absolute viscosity of the oil at 100 deg C (operating temperature).

 

Wow!!!
I am sorry to start such a sh.. show.. I am switching to 0-30 Signature series Amsoil next oil change. I have used amsoil for years in all my
Toyota pick up trucks and in my honda s2000. Has always been good to me.
Dare I mention and start the direct injection issues Toyota and Lexus have had with carbon build up thread,
Lexus actually rebuilt my wifes IS250 engine due to carbon build up. Amsoil Signature series oil claims to help
prevent carbon build up with GDI engines.

Not the same engine. Google cleaning cycle on our engines.

 

I suppose you mean Direct Injection and not Ignition, our engines have a cleaning cycle that prevents carbon build up so it should be a non issue.

 

The replies from the last 2 posts are right . there are many articles on this but here is 1 .

This is the main reason I bought the Tacoma over a different truck in 2016 . It is also why Ford had to redesign the ecoboost engines fuel injection (carbon build up) . Google carbon build up for Fords and find out that before they went to a dual injection system like Toyota , the only way to remove the carbon was to remove the heads . If they ran a cleaner through the engines it dislodged carbon and destroyed the turbos .

 

Here's what I found during my research for this thread.

Have to ignore the self-grandstanding, but looking at numbers and methodology, I like the list.

The amsoil 0-20 looks to be much higher ranked than their own 0-30, with mobile 1 0-40 pretty darn high up there too (the one I use due to ease of procurement).


Funny that after I get back from the weekend, people that were arguing with me now basically also say that higher weight could be better for longevity.

Doesn't change their recommendation though b/c of legal concerns. Which is totally understandable, I'm just happy more people are making informed vs blanket choices

 

Wasn't going to post here again, but thank you for that great report. Particularly since he ranks Amsoil so high and recommends 5000 mile changes, both which I do.

 

Many users have sent their oil for analysis and none have shown any problems with the 10k interval. Why would you put more weight on some guys word over actual results and testing?


Confirmation bias.

From the link above:

My advice is, ignore any critics of my Blog, because they have always been wrong, and cannot be trusted. They are not Engineers, they don’t have Credentials, they don’t have in-depth real world experience with engines, and they have never done any testing themselves. So, they draw all kinds of incorrect conclusions and assumptions about motor oil, since they have no idea what they are doing. They read a few lame Internet articles, and they think they are experts. But, they are completely clueless that some technical information they read about motor oil, is so highly theoretical, that it isn’t even a factor in the real world. So, they don’t even know, what they don’t know.

Lol.

 

Hence ignore the self-grandstanding. I find it a turn off personally. But I also don't ignore data, after trying to comprehend how that data was gathered and analyzed.

Somewhere in that novel it also says something which I agree with.
Paraphrased: Doesn't matter what oil you use as long as your engine design doesn't require a higher wear resistance. If you meet the minimum requirements, your set since most wear points are protected by the incompressible nature of fluids.
