Congrats on your M3! I use Mobile 1 10w- 30 all year round and for the air pressure I usually have them at 32 psi, but if you look inside your door it will tell you the recommended air pressure. Hope this will help.

that's only 2 questions

oil weight depends on location and local temps really.


Tire pressures for regular driving I would just follow the values inside the door jam.

[m3f_fun2drive51]

Concur oil depends on location. I assume you didn't get the manual because it is in there. Door jam has the pressures but typically 32 psi all around. I don't run that I run 34 psi. I do run 15W-50 Mobil 1 most the time because I am in Florida so with that heat I prefer a heavier weight...

I like to run a little bit higher tire pressure, usually around 36-38psi



Oil weight depends on local weather (temperature). My car is a summer only car and runs 15w40 Royal Purple...

Mobil 1 15W50.


34 psi all around.


Advice for you: start a Money Market account for your M3.

Oil who uses oil? You mean you are supposed to change that stuff? No! I read somewhere it was BMW lifetime fill... (kidding, sarcasm aimed at newbs)



In the winter I use 10-40, and in the summer I use 15-50 don't have any issues.

Sarcasm from you!? jk Any specific reason you run different front/rear pressures?

[m3f_socalsport]

thnks guys, well i live in southern californi so its pretty hot, since i been reserchin, i m leaning towards 5w 30 oil, 15 40 seems so thick, but i dont know manul says 15w 40 its hard for me to find a synthetic of tht close to me for some reason. so 5w 30 for so cal?

[m3f_Richardsperry]

Even tire wear and I think it handles better.
