same. not sure when they started using knock sensors, but all new engines will have them

 

[&:] this will hold true for all engines. if it does not knock then the octane your using is fine but be sure you know what to listen for cause if its doing it the computer retards timing losing power and the detonation part tends to blow holes in pistons if allowed to go on for too long. in other words you cant go wrong with a higher octane (within reason) it just costs more kurt

 

alright... because i've just been runnin 93... and i'll probably run 100 or somethin after i replace my bad o2 sensor thatwas supposed to come in the mail a few days ago

 

I was talking about knock sensors and KR, which is only in newer engines. Older engines will just knock, while you are less likely to hear a new engine knocking because the computer pulls timing until knock stops or until a limit is reached. Carb engines for example have no computer and will simply sit there and knock until u make a change in timing

 

79 in California.The computer controls started out stricktlyas emission equipment and we get it all first.Yes even the carbed engines had knock sensors.

 

ok ok ok, im speaking too generally
the point is dont rely on sound for a newer engine because chances are the engine isnt knocking anyways, its just been retarded to the point the percieved knock went away, thus addressing the OP's question. oh, did I mention: ""

 

Yeah no ****! Most of us in California have known that since 1979. I just don't consider 79 newer.

 

On a stock motor, whatever it may be, it's dumb to run anything over 93 octane because the manufactures make sure you can run on regular pump gas, no need to run 100+ octane in an LT1 or a 3.8L...c'mon guys, use your heads!

 

thats retarded esp if the 100 oct you are getting is leaded, the lead fuel kills 02 sensors

 

[&:] wholy crap batman its kinda all over the board here. specter my second post was in reference to my first ,Not your posts. knock sensors have been around for awhile and unless im mistaken a knock must first occur before KR happens which translates into you should be able to hear it happen. and for all those frontin high HP numbers with super cool exhausts that are too loud to hear any knock maybe you should be more in tune with your hot rod to tell when KR is droppin your HP or at the very least make a run or two with a scanner hooked up to see if detonation and KR are occuring to avoid holes in the super HP pistons. really folks detonation is not a silent killer it makes itself known in both computer and non computer motors and if you cant tell when its happening you need to spend more time with your favorite motor. 92-93 octane will take care of most streetable built motors, 100 would be overkill. as for o2 sensors and lead.... well im not aware of any gasoline produced anymore that contains enough lead to damage much of anything let alone an o2 sensor. they really dont like antifreeze and some goops and goo's but most of those have been eliminated from the industry(noncompatible goops, goo's) since o2 have become the norm
