I started puting 93 octain gas since I got the car like 5 month ego the oil is geting black to quick my dad says that my car dosent burn the gas all the way and the particles get in the oil.

Correct ? Can my car burn 93 octain ? if not what dose it burn ? the lowest one or the mid one ?

Or my oil is black beacuse of somthing else ?

Do u think if my car burns 93 octain it even makes a diff if I put that in ? But I do drive on a highway almost averyday so I was thinking higher octain will get me batter milage ?

using 93 octane will not cause you oil to turn black quicker. Your car probably has high mileage on it. there fore lots of wear and tear on the internals of the engine. It is normal for oil to turn black that is what happens as the viscocity of the oil wears down. Just change your oil and oil filter. I personally use Mobil one synthetic. you probably want to use 10w30 in your car. But I know very little about anything but old chrysler products.
