so i know it sounds dumb. But i accidentally out engine oil in my brake fluid reservoir. i just bought the car and they are close together and the reservoir cap is heavy duty and kinda looks like an oil cap. anyways im dumb blonde okay. it was only about a quarter qt before i realized what i was do…

It must be flushed out immediately if you want to prevent damage. Even then, you may still suffer damage at a later date. Be sure and tell the shop what you did. They may also ask why the brake reservoir was so low to begin with. That in itself may indicate another problem. If I may ask, if you are…

You’re going to be a lot poorer after the BMW dealer’s service department gets through with you. Putting the oil in was your first mistake. Driving the car afterwards was your second. Have the car towed to the dealer, tell them what you did. See what they say. If they start off wanting to change eve…

Concur w/advice above, most important priority is to not drive it , or even step on the brake pedal. Have it towed to a shop (doesn’t have to be a dealership). They’ll probably first use a turkey baster to remove everything in the brake reservoir. I think if I had this problem myself I’d try to u…

I would assume that the engine oil has not travelled far from the master cylinder…unless the two fluids intermix. The turkey baster followed by disconnecting the brake lines at the corners might be better than running the bad oil through all the calipers.
