I was browsing my350z.com and came across this thread it said,
"A couple weeks ago I posted a question regarding the use of synthetic oil. I decided to send Nissan a question asking whether or not synthetic could be used and how that would affect the warranty. Here was their response:
Thank you for contacting Nissan North America, Inc. and allowing us the
opportunity to be of assistance.
Nissan recommends mineral based oils. We do not recommend synthetic oils due
to possible engine damage.
If you have any further questions or comments, please feel free to e-mail
National Consumer Affairs"
I wanted to get your opinion on this, because I am currently using synthetic oil in my car. I also heard that a test was done that proved that Walmarts brand oil filter (super tech) is pretty damn good. What do you guys think?
