Everytime I check the oil, there are tiny air bubbles in the oil on the dipstick. Is this a problem?

 

Can't see how it would be. I'm assuming you are checking it after you've driven or warmed up the car. That being the case, why not check it before firing it up and seeing what it looks like?

 

Yup, usually let it sit for a couple minutes before checking. When I check the oil cold, there are no air bubbles.

I've been reading online and I've seen that it could be due to either water getting into the oil or me overfilling the oil. The oil does reach the top of the dipstick when I check it, but I doubt I have overfilling issues. I have no clue on the water leaking, but that seems highly unlikely.

And again, some places say that it's perfectly normal...

 

Wait.. the top of the dipstick? or the top of the full mark?

 

If you had water (or coolant) in the oil it would appear milky.
