Guys,

I have left limited bottles of the Castrol TWS.

Please note that not all 10W60 viscosity engine oils are the same.
Get the genuine approved Castrol TWS Motorsport 10W60 engine oil for your ///M!

Cheers!

wow its very interesting

Wow thats seems really interesting. Thanks for sharing ...

Castrol's Edge Sport is also good enough for the ///M engines, and the price at a fraction of the TWS.

This confirmation came from Castrol themselves. As for the oil filter, the S54 engines can use the regular M50 oil filters.

Data provided to me from Castrol, as you can see the Edge Sport 10-60W is not far off from the TWS (flash point and viscosity).

Thanks for the chart and your input Albundy.

Firstly, I wouldnt take the risk of putting the Castrol Edge Sport.
Just do a comparison between the two charts and look at the differences. Differences might be minimal to you or "not so far off" but what about the long run of the engine considering the air density and the humidity of our country.

I dont think BMW would invest so much on Castrol just to research and to formulate a special oil for their M cars if they are able to use the Castrol Edge instead.

Yes. You can use a M50 OF on a S54 engine but would you? Furthermore have you ever compared the 2 oil filters properly? I wont debate more. Bottomline, the car is yours and the option is yours. If you wanna be economical and you wanna drive a M car, goodluck!

Alot of us have the "tidak apa" attitude. When things go wrong ppl will start blaming the workshop instead.

Just my input and hope it educates ppl. Peace and cheers to all!

Actually TWS is not the only oil specified by BMW for the m engines, not the s54 for sure. The other recommended oil is formula RS which I was told by castrol is similar to the Edge sport, as both oils are of group 3 base compound, whereas the TWS is made from group 4 compound and hence the exorbitant price.

As for the data provided, I am more than pleased to use the edge sport as I have done for the past 7 months, and given the fact that I change the oil religiously every 4-5k kms as recommended I don't think oil degradation is an issue. As for oil filter, the filter for the s54 is same as m50. So again there is no issue as long you use an original filter.

On the track the edge sport has shown to be reliable in terms of oil temp, despite the hard driving it rarely goes above 125 centigrade, which I have checked with other M cars running on tws also reported similar oil temp.

Cheers

There are alot of threads debating this on other forums especially m3forum.
The general consensus is Edge Sport 10w60 is not the same as TWS, it lacks certain additives recommended for our engines.
however, if you can get hold of some EDGE, that is very similar to TWS.

Personally though, i would stick with TWS just to be on the safe side.

Well the EDGE only comes in 0-40W, and the similarity is in the base compound as I wrote earlier.

AS for the addictives in the oil, Castrol has informed me the Edge Sport meets all the requirement for the M engines.

Again, this is just additional info for the members. If you want to use TWS, by all means do so.

Cheers

in my car user manual they recommend to use Castrol TWS and the BMW LL-01 oil 5w-30...seems like a totally diff oil recommendation...haha one come from the designer and one come from the marketing department...

Actually for the S54 engine, BMW also recommended the 5W-30 originally before the conrod bearing and oil pump recall. Of course it wasn't an oil specification issue but more so due to the oil pump failure.

5W-30 more vrroommmmm

 

[t2ribena]

maybe i shud try the Castrol SLX Powerflow 0w-30...still have some in stock from my e60...haha

regarding the TWS i have downloaded the S62 oil analysis data for a collection of engine oil and from what i can see the element amount found in the oil is very similar between the TWS and the EDGE SPORT...the BMW LL-01 5-30 also shows similar result...Mobil and Royal Purple not very good...haha....

Can post it here for everyone to view?

Guys,

Oil temp doesnt really concern me.

Have you check out the oil pressure during hard driving between the two oils or scuffing marks on bearings after 100,000kms?

Oils will be oils..Most oil works on most cars and what you pay is what you get.

Like said. You wanna be economical and you wanna drive a high performance car its up to you.

These TWS were recommended, sold and imported directly from BMW USA. If you wanna doubt the manufacturers of your own vehicle its your call.

Cheers to all!

fren i know you wan to sell the oil but be abit factual...brushing off constructive discussion does not help...

why does oil temperature have nothing to do with the oil? the fundamental of engine oil function is to lubricate and cool down the moving parts, if there is insufficient lubrication on two moving parts, more and more heat will be generated apart from the parts wearing down quickly. These heat has to go somewhere, to the coolant and the oil. Higher than recommended engine oil temperature directly indicates that the oil could not bear the load provided all the cooling system is in proper condition.

There has been rod bearing damages on the S62 engines which is known to only use TWS and religiosly changed at 6000km to 7000km...below is an example of the bearing (from M5Board forum)...

so using TWS does not guarantee you that you won't have premature bearing damage...

okay...here the simplified list from long lists of oil analysis report...here only showing the TWS and the Castrol 10W-60...report from USA (download from M5 Board forum)

 

[GT35R_BMW]

T2ribena,

The damages on the bearings could have caused by various signs of fatigue of the engine. What confirms you that it was caused by the oil? It might caused by improper installation of bearings, inaccurate bearing measurements, failure of oil pump, stucked debris or steel particles, etc.
Anyway, I didnt brushed of the contructive statement of oil temp isnt important. But for me oil pressure would always be my priority.

From your quote "if there is insufficient lubrication on two moving parts, more and more heat will be generated apart from the parts wearing down quickly"

Less oil pressure = more friction = more heat.

Im not forcing anyone here with my oils. I quote whats written on the manual and quotes from Castrol themselves with the TWS. Anyway dont get me wrong. Im not here to sell my oils. Im just hoping that Im able to provide the forummers with a much decent price for these oils.

Cheers!

 

[astroboy]

This one?

or this one?

Dunno why the different color packing but I believe one is American and the other European.. if I have a choice, I'll take the European.. :listen:

 

[GT35R_BMW]

The Silver bottle is the older packaging of TWS.

The Gold bottle is the current packaging of TWS.

Firstly, i did not blame it on the oil, i was merely stating in reply to your claim that the bearing can also get damaged eventhough it is on TWS as per your statement that if you do not use TWS you will have problem with oil pressure and scuffing mark on bearing...

improper installation, inaccurate bearing? these are factory fitted by BMW and failed at >100000km...if those improper and inaccurate things you mentioned is correct then the bearing will be destroyed sooner than 50000km...failure of oil pump would cause much more damage than the bearing alone...no?

why not enlighten us with your oil pressure defination? how that the TWS affects the oil pressure than other oil and in this case the Castrol Edge Sport which has the same viscosity but of type IV and III oil respectively?
