Hmmmm not quite Bret as BMW also say it's OK to change that said oil just the once, every 12K miles and we all know there is a bulletin floating about (come on Alexk ) that recommends far more frequent oil changes on our S54 engines. Considering some (cough, cough ) CSLs are used mainly on Track I for one don't trust everything BMW say . Looking at the technical data both EDGE oils are very similar so I wonder how one 10W60 Edge oil is not quite as good as the other. Since I change my oil every 4000 miles (that's two additional oil & filter changes in between scheduled BMW service intervals) would there be any noticible differences with detrimental consequences ?
I've e-mailed the Oilman this question directly.

Spot on. The Edge Sport is for other things, like some Alfas, Astons, Ferraris and a couple of bikes, although with the price of Astons and Ferraris, surely paying a couple of quid extra and using the better Edge for M-series is worth it. I don't really understand why they make the Edge Sport as it tends only to be relatively expensive cars that use a 10w-60 and there's no point in cutting corners with the oil.

The Edge 10w-60 has an ester content, which the Edge Sport doesn't and that makes the Edge a better choice for track use as it's a better lubricant and more stable at higher temps.

THANX Oilman... Ester content making the oil more stable at high temperatures is good enough reason for me to keep using EDGE 10W60 M-series and I agree with you on WHY? bother having Edge SPORT, when the EDGE M-Series is a better oil.

But realisticly if your doing oil changes often anyway I recon both are fine. I use edge sport in mine and do oil changes every 5000km's or after every track day. I know mine isn't a CSL but it does make 400rwkw and never been an issue with edge sport.

I personally think the only reason to stick to edge/TWS is if you stick to the factory BMW servicing which I don't recommend. It's too far between. But if you do I think that would justify staying with using the factory oil.

I hear what your saying I do have my CSL serviced by BMW Main Dealer as it's under their Warranty (and a requirement) + I feel it's best to keep that up on a car like the CSL., however it being my weekend TD worrier I change the oil at least twice (every 4000 miles) in between scheduled BMW services as it's oil does get a proper work out (I have seen the oil temp gauge nearing the 125 deg C marker on a few Ring laps
We're all waiting to hear back from Alexk who has a copy of bulletin expressing similar sentiment about more frequent oil changes for the S54 engine Should be an interesting read.

The way I see it is that the Edge is the better oil due to the ester content, so for an extra £5 or so per change (and that's without considering our offers), you'd may as well go for the Edge

I agree... the tiny extra cost isn't the issue here. I was just curious why there were two such similar Castrol 10W60 oils considering the kind of cars that require this oils. Surely a Ferrari owner would want the very best oil possible for their pride & joy, just like any CSL owners.

[oilman]

I think it's because Castrol like to confuse people. With the minimal price difference, I can't see any other reason to make the two oils. When I say minimal price difference, that's with us, it may be different elsewhere.
