I recently switched form castrol syntec 5w30 to mobil 1 synthetic 5w30 and now when I am in traffic the car gets noticably hotter than it ever used to. With castrol syntec it would NEVER go past the mid point of the temp gauge (90 degrees) or (195 F) now it goes 2 - 3 small ticks past the midpoint. could it be the mobil 1 oil making it run hotter?

my car always runs that hot in traffic, maybe your coolant is just gettin old.

try getting/doing a coolant flush. Guaranteed it will help.

yeah, mine runs that hot in traffic as well. There is nothing wrong with your oil or your car

I've never seen my operating temp fall below the midway, 200 point.. I have seen pics of other people's OT's, and my car has just never ran that cool. I never thought that it may be oil though. I use mobil one too, but not synthetic.. hmm.

I don't think mines ever been under the middle point when the car is heated up. I wouldn't worry about it.

2-3 lines past isnt that big of a deal. Do you have a Warm Air Intake or something?

The only thing that could help is a coolant flush, if not just leave it alone.
