A couple of weeks ago I change the oil and put in new Mobile1 0w40, and a new filter from the stealer..... The next morning I noticed that the car started up somewhat rough. This morning even more so, there was almost a grinding sound, but I had the radio on and by the time I flipped it off the sound was mostly gone.

But it almost seemed like the engine had a hard time running at idle for the first few moments.


I just returned from a 10 day 4000+ mile trip and had chagned the oil just before the trip.

As far as I can tell from reading the dip stick tehre is plenty of oil in the system, but should I check after the engine has cooled down for while?
