2002 Mazda Millenia stalls?

[maynardk1]

There was nothing wrong with my car last Friday except the oil level was a little low. This didn't affect the cars performance. Now that I put some oil in it, the car is jerking when I drive it. If I am at a stop for too long, it stalls. I don't know what kind of oil was in the car, but the manual said to put in 10w-30, so i did. Could mixing two types of oil cause this problem or is it something else? The engine light is not on or anything.

I thought your foreign cars were of such superior quality? There sure are a lot of repair problems for them here. Anyway, no, mixing 10W-30 with another oil like 5W-30 or 15W-40 for that matter would cause this.
