Engine Ping on 91 Octane

JSBZ · 05-14-2012, 12:38 PM

I will get pinging at moderate load if the engine oil is running high >210.
91 octane is the highest available here in CO without going to race gas.

I jut got my 2013 370z about 3 months ago. I've had the same pinging problem since day one. It does it after the car gets really hot and mostly on first gear. If I ease up on the gas pedal just a tiny bit it will stop doing it then I can accelerate without the ping. Once I'm in second gear it stops. The highest octane available in Las Vegas is 91. I've been using NOS octane booster for a while but It doesn't make any difference. When the car gets hot, the engine pings. I'm going to stop using NOS because I've read mixed reports about it. I'm going to take the car to the dealer in the next week or so. I will post my findings as soon as I get the car back from the shop. Other than that, THIS CAR ROCKS!
