I have used that too. As a side note though, my trunk is no longer closing properly. I'm wondering if this could be the cause. This morning I had to try 5 times before I got it to catch and this while FIRMLY pushing down on the lip.

Had it at the dealer yesterday for that, the sunroof piece that falls off, the jerky first 3 miles after starting in the morning and $40 oil change.

They didn't have the piece to fix the sunroof even after I had told them it was damaged when I scheduled the appt. The service rep told me that the tech said the hard closing trunk was normal with the infinities and they obviously couldn't duplicate the the cold running condition.

I'm quite a bit dissappointed. I usually change my own oil and would have except I thought what the heck since it was in for it's design flaws anyway. The last oil change I did was with Mobile 1 and cost me maybe $30. They use non-synthetic Mobile for $40 and the rep practically told me if I had to ask how much for them to use synthetic... Hugh waste of my time and money!!! I now have to go back again when they get the part in.
