TSW 10-60 M-Power Oil vs. CASTROL Synthetic Oil

Dealer recommended TSW MPower 10-60W Engine Oil....vs. CASTROL Synthetic Oil 10-60W. any suggestions? i'm thinking of switching to synthetic oil... pics soon!!

Castrol doesn't make a 10w60 unless it has just come out. Castrol DOES make the BMW labelled 10w60 and is available outside the dealer but only in Europe.

You should be using synthetic anyway. The M5 gets 10w60 if it has a build date of 3/00 or earlier. Build dates after 3/00 can use 10w60 or 5w30.

In the interest of clarity, build dates after 3/00 can use BMW TWS or BMW 5W30. Using 5W30 from any other manufacturer is a no no. Valvoline is 5W40, Castrol is 0W30, and Mobil1 is 0W40. There are others I'm sure

Ancient thread I can see, but just had this conversation over at M5 Board. Liqui-Moly 10W60 is good alternative to Castrol and MUCH cheaper.

Just jump on the grave dig train If you switch over to Liqui Moly I suggest the Race Tech GT1. There are a few variations they make, the GT1 is the correct one for the S62.

Wow, this stuff gets complicated doesn't it? Just like always with these cars.

Luckily, GT1 is the kind I picked up!

I'll bite...

Based on what?


Edgy- you'd be surprised to learn the higher viscosity actually runs HOTTER, not cooler....

I have an 01 M5 and have been using Mobil 1 5w30 for 4 years, Why is this a no no?

Gary -- many threads on this, very subjective topic. Check out my post, has links to other discussions.

Probably nothing wrong with 5w30. But in South Carolina, there is no reason you need to go that thin, and 10w60 gives the engine better cooling due to the broader viscosity range.

That oil is significantly THINNER than the recommended BMW 5w30... And THAT is way thinner than the 10-60

If you look at the actual viscosity specs of the BMW 5w30 it runs like a 5W40....which is why Doug Baker (above, 4 year ago... wave) suggested those oils.
