At idle in the cabin I hear the engine. I don't know much about engines but am i supposed to be able to hear the movement of the pistons or something when idling? sounds very machine like.
I was told on a few occasions that my car was pinging though.
Zcar garage let me know that i was pinging at high rpm.
and an infiniti tech said that i was pinging because i was not using premium fuel I always use premium in fact, the only type of fuel i use is shell v-power

 

i noticed my car was pinging when i used shell v-power

then i switched to chevron and my pinging was gone

 

Damn lol. It's worth a try but why did it work.

 

I only use shell v-power and when its not around chevron is my next choice. Both i believe are awesome fuels to use. I just prefer shell gas over chevron, but my dad has always told me to use chevron.

Whatever!

I never get pinging from either one though

 

^^lol i used to be just like that...shell first, chevron second

but then i switched to chevron recently and the pinging was alllll gone! it turned me into a believer!

(dont get me wrong, i have nothing against shell...i still use it when chevron isnt around )

 

Maybe ill give it a try for a couple weeks see how it runs...

 

^^do you guys have 91 or 93 in florida?

just curious

 

93, i think i have actually seen 100 at a couple sunoco stations.

 

Isn't pinging only a problem with turbo-ed cars? This probably isn't the same problem you guys are experiencing.

 

Yeah its called knocking not pinging, but we knew what he was talking about.

 

Where in FL have you seen the 100 octane???

 

Engine's been knocking for a long time ... after MREV+ installation. Any solutions? or will I have to get UTEC?
I don't see why my engine would knock with MREV+ alone. Everything else is stock.

 

This was a couple years back, but between anna maria island and siesta key their used to be a sunoco that carried 100 octane i havnt seen it since then, but im sure if there was one there that there has to be another one somewhere.....

 

Have you dyno'd since you've added MREV+? A/F ratio? You could be running lean, which could result in pinging or detonation.

 

i did here's a link to my dynos in a previous post. everyone including tony from hydrazine said i was fine.
