Just wondering if I should check the fluid when the car is not started and sitting for awhile? or does it not matter. Because I checked it a couple of times and the fluid level has been varying.. car has 1400 miles on it, and when I checked this morning it was below the "Min" limit. while a month ago it was at "Max".

 

Fluids expand with heat.

 

So could it be just because it is cold outside? That is why the fluid level is so low?

 

I think the temp does make a little difference, but if its really low i wouldnt blame it all on the temp.

 

Normal. It will go up and down with temp and use.
