I was thinking of putting in regular antifreeze from napa in my 996 c2? or should i use the original porsche coolant?

 

porsche original. i hear that the porsche doesn't mix well with regular antifreeze. porsche coolant is very expensive.... if you just need a cup or quart, you can just add some distilled water - sold at grocery stores.

 

get the OEM one.. you can buy it from suncoast online

 

suncoast, plus 1 on that...they are the best....
