i switched over from dino oil to mobil 1 5w-30 at 80k miles. My car is now at 96k and did a oil change two weeks ago...hardly any oil is burning. I believe my engine is in super great shape.

btw...i am using 20w-50(i think thats what i bought)in my car now. Since its getting old, i'd figure better protection. Am i thinking right?
