New 10w60 default oil from BMW. No more Castrol

I'm pretty sure they used to say TWS was the only "approved" oil.

are you saying BMW and Shell will devote the time and money to develop the oil specifically for an engine that BMW doesn't even make anymore and doesn't profit from? That's just incomprehensible. Most likely they just grabbed whatever 10w60 oil Shell had that was as close to TWS as possible and just stuck a BMW label on the bottle that says "approved for M engines".

Bingo!

Interestingly on the UK and German Castrol website they still claim exclusive M approval for their 10W60.

Not to fan the flame of another oil argument, use whatever 10W60 YOU want. If something happens to the engine due to oil brand or additive package, well then at least YOU get to deal with that. No one else can be to blame right?

You're kidding? It's a business deal. Shell pays BMW to use their brand and now BMW will endorse them, that's all.

My owners manual says "Approved oils belong to the 10w-60 SAE class". Does not say you can only use Castrol (although it does say BMW recommends Castrol).

On this forum we have beaten to death this Castrol TWS argument. Enough is said.

What this means now is all along we could have used any 10w-60, what we were made to believe was the engine would have gone kaput if we had used anything but TWS and voided the warrant. Simple.

but but, isn't the S65 'specifically designed' with the very original Castrol TWS (not even the edge TWS).

j/k.

The question now is how many will still stick with Castrol?

makes no difference to me..
have been using Liquimoly all along

Great to see what the new 10w-60 is all about (and how different it is from the TWS).

Myself I just recently bought a E90 M3 and just changed oil with a blend of TWS and M1 0w40. Many on here have UOA for TWS that shows higher wear amounts and using M1 0w40 have decreased or eliminated some higher readings.

Now, i am SURE TWS and a heavier weight 10w60 will provide MUCH better protection when the engine is being pushed and ran hot (for example, during HPDE, Auto-x, track, epic long hot mountain runs etc), but for a lot of us here we DD out car, rarely go above 4-5k RPM. For myself espcially, being in Canada (Vancouver, where temperatures aren't as severe as back East), running 10w60 seems to be an overkill.

But as many mentioned, topic has been beaten to death. And in all honestly, only a handful (VERY LITTLE) people have ever had engine problems related to oil choice. Just simply use whatever oil you feel like that makes you feel good and change it often to keep it clean and healthy!

Shell Helix spec sheet (top) vs Castrol TWS

They are VERY similar by these specs.

Does that mean the Shell is even thicker than Castrol?

Time to do some more reading. You're not supposed to mix those two oils. Just pick one!

Damn that stuff is thick.

I highly doubt it's that simple.
Look maybe you have some additional insight that I don't however what I can speak to is that I've been working for Tier 1 suppliers for some of the largest OEM's in the truck and car markets for many years.
Each one of them have specifications for us to meet as well as continuous involvement in many facets of the quality and product manufacturing.

I stand by my position that BMW had involvement with Shell to help specify either additive requirements or specification boundaries.

for a new development maybe, but Shell has already had a 10 60 that met the M car requirements.

He posted Redline specs in the post. Shell appears to be very close as far as the documented specs read.

It will be interesting see if Castrol (Edge) TWS 10w-60 will now be available on the open market at a reasonable price. If the price is right why not continue to use it. Makes $$$ sense

If you consider AutoZone (in the states) open market, I'd say we're there.
