What is the advantage of using oil meant for a diesel?

2. The air and heat blow almost completely out of the two middle vents. The far left and far right vents are VERY weak or don't blow at all. What could be the cause of this? If I shut the middle vents the side ones do blow, just not when they are all open.
You may have an issue with the hvac system, since you should not be getting any heated air through the center vents. Mercedes during this period didn't think it was a good idea to have heated air from the center, only the sides, footwell and upper dash vents get air heated by the heater core. The center vents only get ambient temp and air conditioned.

After playing around with the climate control today, I noticed that cold air is only coming out of the center vents, while the heat doesn't seem to work at all. Any ideas as to what to check for that?
The air is decently cool when driving down the highway, however when I stop the car at a light, or at idle, it warms up considerably. I'd like it to be ICE COLD even at idle.
In an effort to fix this, I went to the auto parts store and bought a can of coolant, but when I hooked it up to the system, the gauge told me it was already at max pressure.
So, is there anything else I can check myself as to why the air isn't too cold? I don't want to take it to a shop unless I absolutely have to because of the expense.
