got an 82 12a with the big oil cooler under the radiator.How much oil does it hold with the cooler? My local parts store says 4.something but I figured some of the 7's dont have the big cooler so the ones with them must hold more than the others not equipped??

 

Start with 4 and add accordingly. Mine usually takes no more than 4 or a little more

 

Just make sure you don't overfill it!!!! This will blow out the oil control rings and leave you with a smoking motor....

 

Thanks guys guess I will go get 5 quarts and start with 4.
