Worked great in my Infiniti QX4 which has the same engine--see the UOA forum for the UOA. The worry about cat pollution is significantly overblown, IMHO, unless your vehicle guzzles a quart every 3K or so. I've owned two VQ engines (I used to have a Maxima with a VQ30) and neither engine has used a measurable amount of oil, even with 7,500 mile OCIs. I think the chance of damaging the cat with these engines is virtually nil.
