Drain it and replace the filter. The amount of money you will spend on an oil change is significantly less than a catastrophic failure.
If you didn't start the engine I wouldn't worry about the filter at all because none would have gotten in it. And to be honest if it was only a tiny bit I wouldn't worry about the filter even if you did start it, I might dump it then put it back on.
All of the above. Change the oil and filter. Do not start it what so ever.
I feel like a idiot but I was talking to my brother and wasn't paying attention just grabbed it thought it was oil then when I was pouring it realized it wasn't didn't get much in there but what should I do just drain the oil put new oil in and should I change the filter too
