It should tell you in the owners manual or you can find out in a Haynes or Chiltons manual that you can probably find at the local library if not buying one is a great investment and should be able to find one at a local parts store or online.

I have the Chiltons manual and i didnt even think to look haha. somtimes u just have to do a little reading to find the answer.

 

12qts is the dry fill... A pan drop and filter change will probably only swap out around 6 quarts. I usually put about 5 qts back in, then check the level after starting the engine and running it through all of the gears, then putting it back in park.

 

Thanks guys it was only 5qts now it's going a little better.
