So I grabbed the wrong bottle and accidentally put no more than 2oz of matic-j in my power steering fluid resevoir. I'm not sure that it matters much, since the power steering fluid calls for ATF. I was checking fluids and changing oil and it looked just a bit low so I wanted to top it off...wish I hadn't.

2007 G35x if it helps....

anyone have any input on this...

 

You should contact your local Infiniti dealership to confirm. J-Matic is ATF from what I know...

 

You should be fine. The power steering calls for dexron III ATF, which might be the most generic type of ATF out there. Adding 2 oz of matic-J isn't going to hurt you.

 

^^ That was my assumption too...thanks for some piece of mind.
