Found this white spot under car after I had some water get into the garage.
I think it may be front center area(slight right) or may just something else on the floor that got wet. Kinda white. Didn t feel real oily. ??? Didn t see anything on under side of car after a quick look. Thanks

 

Condensation from A/C??

 

temps still 30-40, haven t used AC or defrosters.

 

water(evaporates) and then salt from the roads possibly?

 

doesn't look chemical,, probably from A/C////I saw drips from area under shifter on ground, was H2O from AC goings on

 

Thanks guys. It has dried up and is white and chalky looking. Maybe salt as stated?
Going to put it up on ramps this week just to be sure. Any other suggestions or places to look from underneath is appreciated. Will post my findings.

 

Given that you have water in your garage it's probably related and not a leak. Clean it up, check underneath anyway, and put a piece of cardboard under the car for a few days.

 

No, that's a drip.

This is a leak.

 

Lol!!!

 

Looks to me like you have a stain on the floor from water entry into garage that is most likely not car related.
