My car (2005 325i) takes a lot longer to heat up in the winter than some of my previous cars.
The car feels rather sluggish in the winter. In the summer the engine runs super smooth and is a lot more responsive.
Do you think switching from a 0W40 oil to a thinner one can improve my winter performance?
How thin do you think I could go on a M54 motor?
If you are thinking thermostat, mine is 2 years old. It seems to operate at 92 Celsius instead of 97 Celsius like it's supposed to. However, there are only two brands available, Behr and Wahler. One brand leaks from the temperature sensor and one brand runs a bit cool. So given the choice between the two I would rather run a few degrees cold than leak coolant.
