Castrol 10W-60 TWS - ZR-1 Net Registry Forums

Scrrem · 04-27-2015

I used up the last of my stock of BMW 10W-60 TWS oil with a change on Sunday and when out searching for more and found that BMW/Castrol may have renamed / rebadged the oil. One site I checked said that the TWS oil and been discontinued and replaced by the product below. Hopefully it's still the same product inside the bottle. Can anyone shed some light on this?

I found mine here when looking for some allroad parts: http://www.ecstuning.com/

I think that it's the right stuff.

Go to BMW dealer, be ready for sticker shock, 1 liter bottles, but cheaper than a Bill B rebuild

I bet they re-branded it so they could charge $24 a bottle. I bought some in 2011 for $15 per at the BMW dealer. I didn't care for the shift quality and now I'm in the Amsoil Synchromesh camp.

I'm surprised to see such a blatant price increase for motor oil.

Why would you run a 60 weight oil in the LT5

Not the engine, the tranny.

Not having any issues other than not being able to find TWS anymore, AND having a little "curnch" when shifting into 5th ONLY WHEN it is cold, on Marc's recommendation I switched to Red Line Heavy "shock Proof" full synthetic 75W-90.

One outing does not an evaluation make, so I'll save that for later. But, once up to operating temps, it shifts like butter - and no crunch going into 5th; very "normal" feel to it. Check w/ me in November!!

Rich,

Funny you asked about this... I need to change my fluid and a few friends want to change their trans fluid. I asked Marc his opinion and go this.

"We no longer use the BMW lubricant because new products are available
that are better.

For a street driven car with the OE dual mass flywheel we use Amsoil
MTF. It's a 5W-30 synthetic lubricant. It's better than the GM lube
that has been discontinued because the GM lube used mineral oil. You
can get it from me or any Amsoil dealer.

For a car with a dual mass flywheel we use Red Line Shock Proof
Heavy. It quiets the transmission better than the BMW 10W-60. It is
also good for racing because it is synthetic. You can get it from
Summit Racing. RED-58204"

Ordered Red Line!

I think Marc meant: For a car "without" a dual mass flywheel we use Red Line Shock Proof Heavy. It quiets the transmission better than the BMW 10W-60.
