I noticed that I had a bit low of coolant level and I have some 50/50 in the garage from prestone, would this be safe to use? I caught the problem before the light turned on and it seems the floating stick is sunk quite a bit. Can anyone enlighten me? And how much am I suppose to fill it up to?

Stuff from BMW. Some might say it's a rip to buy from BMW when you can get stuff for cheaper but it's only $20. On the cap/reservoir/in the manual, it shows you where the stick should be.

Thank you, what's the difference in if I were to use prestone instead? Would hurt the motor? And would it hurt if I overfilled it?

If you are just trying to make up a little bit to get the float up, you can add distilled water straight. Don't put the non-compatible antifreeze in.

If the Prestone 50/50 says it can be mixed then it is perfectly fine to use. Easier would be to just add some more water, in fact that would do a better job of cooling the car.

I see, but its better safe than sorry right? After all, people have told me its a few bucks more but you'll have ensured items for a bmw

yea, bmw coolant isnt pre mixed so it almost works out to the same price as 50/50 pre mixed. For the same money i figure why not. will prestone coolant cause problems? im SURE it wont but why create the possibility for a problem
