Was talking to a friend the other night and he was talking about his buddy's BMW M5 that takes this "special" oil. After some reading, it turns out BMW M-cars take a 10W60 engine oil.
10W60 is a really odd viscosity. It looks like oil of that viscosity costs about $15 a quart.
My thing is WHY? Why such an odd viscosity? The BMW M5 has 560HP and the Cadillac CTS-V has 556HP. The difference is the Cadillac can use normal Mobil 1 5W30 while the BMW has to have 10W60.
Heck even the ZR1 with its 638HP engine uses Mobil 1 5W30.
I just don't understand why BMW wanted to do this. Is it a European thing? Is 10W60 like 5W30 is here in the US?
