When I did my first oil change a year ago I went with Castro’s 0W-40 LL01. I thought it was a pretty good oil but coming up to my next oil change due date, I thought I would change it up and go with Castro’s 5W-40 and see what it’s like. Any thoughts about Castro’s 5W-40 oil? (Haven’t done the oil change yet)

Haha, what do you mean that “it was pretty good oil”?

It’s THE recommended oil.

Are you looking for a different feel or something?

Advice, don’t mess with it. Just put in the factory spec LL01 oil, rather than going on a hunch and trying something else.

Yeah both the oils I listed are within spec I just wanted to see if there would be any major difference.

You'll literally never notice a difference.

I think I will go over to the garage, pull out my Milwaukee M12 drill/driver, mount a 1/2-inch drill in it, and drill a 1/2 inch hole in my skull.

Another oil thread.... Christ.

What car do you have? 335 or 328?

If you have a 335 and it's tuned, you should be running 5w-40. No question about it. Even if it's not tuned, I'd still run 5w-40 on an n54. The engine gets crazy hot from the two turbo chargers. 5w-40 has the best protection properties due to its viscosity.

Why would a 0w-40 and 5w-40 be different at operating temp ? They have the same rating

I hate these stupid oil threads


0w part is better for cold starts.. 5 w has nothing more. Esp when same brand..

5w 40 bullied my brother in high school and toilet papered my house...

5w 40 will never get a dime from me! 0w 40 or nothing!!!

5w40 took my goddamn lunch money one day. He's a real fucking dick, I tell you.

Hey, you do what you want. It's your ride. I've used 5w-40 in my 335i for 140,000 miles. I live in Michigan where we have 4 seasons. In the winter, we see temps under -10 very often. I don't think twice about the 5w-40 in my car, in the middle of the winter. I don't lose sleep about the fact that I didn't put in 0w-40. I think the notion of running 0w-40 is just way overblown. Unless you live in Alaska, you don't need 0w-40.

Like I said, 5w-40 will protect your very hot n54 better then 0w-40 & 5w-30.

Ur pretty much saying i know better than the ratings on the oil put by scientists. You know how that sounds. A bunch of misinformation. If it makes u feel better that 5w-40 protects better than thats all that matters. But are we going to believe that ? NOPE lool

But the point is why not run something that will offer better cold start protection.

Plus the only oil you can get locally that meets LL01 is basically the Castrol that is 0W-40.

[nsjames]

can we just get an oil thread as a sticky for all of these?

The 5W-40 does have a higher kinematic viscosity at 100 degrees C than the 0W-40. There are several other differences between these oils. The 0W-40 comes from Belgium last time I checked and the 5W-40 was produced in the US.

Even two seperate types of 0w-40 will have different kinematic viscosities at 100 c even different 5w-40s will. That will be established based on the modifiers they use. But to say that it protects better is a far stretch. We have no data of that. Use ll01 and ur good.

If that was true why dont u put 5w50... Everything has a limit and its not black and white.

Thats why the ll01 stamp will topple everything .. regardless of weight

What the hell, their website shows the 0W-40 A3/B4 is not LL01 certified yet it's like the only one that is. And shows the 5w-40 with LL01. Hmmm that can't be right?

Unless they just changed it?

LMAO seriously!

[desertman123]

I usually just filter used vegetable oil and run 9qts of it in the crankcase, don't even need baffling in the pan!

Fkn hilarious. Jake Spence a YTuber just posted a very detailed video and post about an a upgraded clutch for big hp N54s. He gets a few replys... but... ANOTHER fkn oil post and everyone runs to it.


Lmao
