I have said that forever people just don't like to listen. LOL
You cant mix add packs after it has been formulated.

Do the different additives counteract? Or do they just not work as well as designed? Or something else?

Funny, because it seems like a lot of the guys who seem to overthink it are mixing mobil 0w-40 and castrol 10w-60, etc. I doubt topping off with a different brand makes a big difference, but several folks are mixing 50/50 which seems counter-intuitive.

It is not so much that it hurts anything its just there are 2 different add packs floating around in the engine. The weight of the fluid will mix and become one. Like 1/2 0wt and 1/2 10wt will become a 5wt but the add packs will never mix. Once a oil is blended from the factory that is it. If you were to add pure zinc to the oil as a supplement to raise the levels it will only stay suspended for a short time before it separates back out and falls to the bottom of the pan.
Like I said, it is not going to hurt the engine it just doesn't accomplish what you think you are accomplishing

So it doesn't hurt but the oil additives don't work together. But it will achieve the mixed oil weight you are looking for.

Correct

Not to sound like a knob, but more specifically:

The additives literally don't work when they're mixed together?

The additives don't work as well when mixed together?

The additives work, but each only half as much?

Or something else?

Thanks

Hmm that makes sense. You're saying it doesn't add any more additives BC they likely settle, as they weren't mixed in an laboratory or manufacturing environment. Good stuff.

They work just as each was intended, they just never really chemically mix.

They will separate back out of suspension the longer the car sits. That is correct, for a true blend they must be mixed at the factory

I hope no one tells my bartender this...

Chemicals are chemicals no matter where they are. Lots of these additives are just elements like zinc, moly, etc. It doesn't matter where they are added to the oil for them to work.

While I don't disagree on the foundation that mixing oil brands is not a great idea; if you drain and refill with a different brand of oil, you will mix brands a bit b/c of the oil left in the oil cooler. However, after the next change you'll be in good shape. It's been done for ages across many different brands of oil and many different vehicles. This isn't like mixing DOT5 and DOT4 brake fluid (which is a colossal f'up!).

[Flying Ace]

The only reason I am currently mixing TWS and M1 is simply b/c I have an extra bottle of TWS left, and it is used as a top off bottle.

Topping off is a totally different thing than blending. Topping off only adds a small amount of oil and doesn't really affect it very much.

I have Liquimoly, Redline and TWS all used for topping off... If it was really a big deal, I'd have quite a mix of oils! lol

yeah, I hear ya. Also topping off is simply adding oil when it is needed.

There is a difference between a suspension, a solution, a mixture, etc. Your bartender should already know the difference... ever order a layered drink?

Every additive doesn't necessarily chemically bond with or dissolve into the oil. Otherwise, metal shavings that accumulate on a magnetic plug, for example, would never accumulate because the shavings would simply dissolve into the oil and form a new solution.

Sure the chemicals might be pumping around, but if they aren't dissolving into the oil they will not have the same effect on the oil as it would if it was chemically formed that way from the factory.

Understood. Good clarification. However, I don't think you're getting calcium, titanium, molybdenum, etc., dissolving in oil or having to be mixed in at a lab to work as an additive. Sure they can be in suspension. I'll have to refer to my CRC handbook and check on the solubility of these elements in hydrocarbons though.

The only layered drink I've ordered is a black and tan. Density! How does it work?

Besides, how's that layered drink stand up to a crankshaft splashing through it 8000 times/minute? I don't think it is still layered at that point, but I'll let others do the experiment (please video -- and wear goggles).

So much so I'm wondering about using it in my S54 too. Anyone have any reports on usage in an S54? The cooler running temps are a big plus as my S54 runs hot (I do track it).

I did a search and there were a couple of posts on Amsoil in this thread but nothing specific about their 0w-40 oil. From what I can tell, it isn't BMW LL-01 approved, but it's late and my eyes are getting sleepy...

Good thread. Love the oil analysis to back things up. My E90M3 comes off warranty in August so I won't be changing oils until then.

Everything I've read on the oil say's it is LL-01 approved. Maybe mix in some M1 15/50. I just got 2 jugs at Walmart and will send in this $12 Rebate/jug.

Gc 0w40 is LL01 approved. Says it on the bottle

TWS, amusingly, isn't!
(Because one of the requirements is weight)

To me, mixing oils implies I know more than the chemical engineers.

I know I don't :P

Exactly. Us ChemE's are a smart bunch...

For the record, I have no interest in mixing oils at home, except for the small amounts left over when doing a full change.

[Montana_STIG]

Hey guys new to the forum! Anyways I just purchased a 09 E90 and the first order of business is an oil change. I've been a huge believer in AMSOIL in the past, they currently carry a LL-01 approved 5w-40 full saps European synthetic. You can find it here http://www.amsoil.com/shop/by-produc...?code=EFMQT-EA

My question is, do you guys think this would provide adequate lubrication vs M1 0w-40? The specs appear to be better however you can't always trust specs from the company sponsored web page.

[Leonardo629]

Amsoil is formulated to meet or exceed BMW LL-01, but it's not certified. The specs are also inferior if you compare VI and HTHS.

At $8.35/qt I really don't know why anyone would choose Amsoil?

Thanks for the input!
