New Member, New-to-me Nismo with Questions

Darkmann

Thanks everyone for your responses and useful recommendations. Did first oil change yesterday using ester oil and Nismo oil filter from Z1. One question, and found out a couple of things I'd like to hear from you folks.

Question: Driving at supermarket parking lot speed, when I throttle a bit and take foot off, I hear a soft "boom" sound like from a subwoofer. It definitely is audio. Is the throttle tied to the audio in this car, for some reason?

Oil Change Findings

1. Spoke with my tech regarding Nissan Ester oil. He says Nissan has asked them to just use Mobil-1 5-30 (didn't question on specific specs). Note: We are small rural with only one Nissan dealership - pretty much one everything dealership (Benz, Toyota, VW, Honda, Toyota, Ford, Buick, Subaru, Chevy.)
   
2. The Nismo oil filter from Z1 shows P/N 15208-65F00, 65F01. shop says -65F00 is obsolete and that Nissan now uses -65F01, I don't see any problems using the Z1 filter in future, but any comment would be appreciated.
