Would you use 5w30 in place of 0w20 oil?

I am done.

Yes, you are.

For those who are of serious intellect here and students (always learning) please pay atn.
There are a bunch of engines that are being produced today that were also being produced before the advent of the 0W20 oils.
Toyota is just one of them.
There is a UTUBE Vid on this .
The producer showed it all , dwn to the size of the bolts.!
The interesting part is that these engines required 5W30 prior to the 0 W 20 fad.
Now 0W20 is recommended, go figure.
And no, no production line changes on the line cards.
None
Right down to the last nut, bolt and bearing.
Now with the B58 (BMW) there have been some mods.
They have removed the plastic liner thing in the oil pump and replaced with steel of sorts.
(the plastic cracked)
As I said, this deal with 0W20 is strictly a fuel milage incentive mandated by big government.
You all do as you wish.

what do you think manufacturing engineers do?

of course the bolts are the same. they are all standard parts. specifications change all the time on a production line. tolerances, couple thousandths of an inch here, couple there. heat treating. casting quality. new suppliers, who also have there own processes that change all the time. things change due to tool wear, tooling quality etc etc.

just because an engine was made 20 years ago, doesnt mean it hasnt changed. it has changed a million ways. have you ever actually looked at an engine? i have 4 mazda b6s that were all made within 5 years, and all of them are different.

but the bolts will be same

As I said, a serious student (who could read / comprehend) will find the swap to 0W20 is at least diametrical and quantitative to the jabbing arguments here.
The 0W20 requirement is certainly a totalitarian mandated requirement and a politically gobermendated motivated program..

since the government isnt mandating what oil you use, or what oil anyone recommends, im sorry, you will have to take that bat **** stupid idea to PARF.

your bizarre paranoid rantings about the goberment have no place here.

I run what the book says in most of my newer cars. On older high mileage cars, I have often bumped up a "tad" on viscosity numbers assuming some wear or if I was only driving the car in the summer months. All that said, I have never had an engine failure due to lubrication and I typically drive all of my cars well past 200K even past 300k on a BMW 325. I typically just buy Walmart or O'reillys branded
cheap synthetic oil for my modern cars and same branded dyno oil for my older stuff.
Oil gets changed around when the owners manual says to change it... Never sooner but sometimes a bit later.

Here is my take on it....
New cars are built with much tighter tolerances in regard to pressurized plain bearings. They get away with this because they are manufactured with tighter tolerances and the engine temps are better regulated which means the bearing gaps stay more uniform during operation. This is why the thin oil works in todays motors. Too thick of oil will mean some of these bearings may not get pressurized enough to provide the proper oil film. Older cars like from the 70's and 80's had larger bearing clearances and thus required the heavier weight oil. Not so much anymore.

[afterburn 549]

As stated- the SAME engines B4 0 W 20 and after, have the same bearing clearances.

These same engines in other countries do not require the 0W 20 oils.
SO
It is pretty clear to me, this is mandated crap.
Of course, everyone is allowed to reach whatever their conclusion is; however, with all the evidence here, it is pretty clear what the answer is.

High mileage oil has seal sweller in it to help control leaks.

[aschen]

Ive consulted experts on specialty oils for use in highly specific harsh use equipment, had a tour of a boutique oil mfg, my next door neighbor is a PHD lubrication specialist at Exxon mobile.

I have no expertise on the matter, but the one thing I have learned for certain is to not trust amateur internet opinions or even high level data potentially taken out of context. There is a lot of potential for unintended consequences here, so I'm going with with what is precisely recommended.

Copied From the article-
One point worth mentioning is that it’s not a good idea to arbitrarily choose thin viscosity oil based on a whim without knowing the consequences.

I agree with the whole article, Burnie, especially the words "arbitrarily choose." Following the manufacturer's recommendation is not an arbitrary choice.

Thank you!

I hate being right all the time.....LOL

[cabmandone]

I'm gonna have to start watching this masraum character... reviving a seven month old thread... pretty suspicious...

Good video btw.

[afterburn 549]

But history combined with current facts makes for the newest info.
The scoffers now are getting educated.
We all need watching......LOL
