This stuff went into my 2005 Pontiac Vibe. It took 2 quarts and at the end I noticed there was some 'sludge' at the bottom of both jugs. this is GOOD sludge BTW so i took an ounce of old fluid (wasn't that old) to give it something to shake around with. I think it's the esters that sat on the shelf for months that settled. Anyways. get it all out of the bottle and you will be good. This MT-90 fluid made my car shift much better too.
