My car has 57k miles on it and I got it as a second hand. I put almost 10k on the car and I track the car sometimes.

Thanks

 

Moved to proper forum

Never. The Z doesn't have throttle body injection (assuming that's what you're talking about).

 

He's talking about cleaning the fuel injectors and the internal portions of the throttle body. We do it at the dealer I use to work for and the product really worked. I would call a local dealer and see what mileage intervals they recommend.

 

"Fuel Injector Cleaning" is not recommended for the 350z. Do a search- there's pleny of info about it.

Use some gasoline with a decent detergent add-in (like Techron) instead.

 

thanks.
I saw the ad at local nissan dealer.
