Oil Question...Please Read!
 

Before you say anything, I have searched and I haven't found an answer that suits my question, which is why this is up.

I know that the milky substance on the dipstick is normal, and it usually means it hasn't been running to normal operating temps and usually happens below 50 degrees.

However, it is 90 degrees here in MD and I was driving around all day yesterday, no short trips. I am not too worried about it right now, I still feel like this is normal, but I just want to make sure no one else had/has this problem and if it might be a bad thing seeing as I am still getting it even in the warmer weather.

I don't believe it is signs of anything wrong, even in warm weather.
what type / weight oil are you using? How long has the oil been there?

I always get my oil changed at the same Mazda Dealer, and they use Valvoline 5w-20. I got my oil changed about 2000 miles ago.
