Time for my first post, I did a search and could'nt find the info I wanted. I have an '05 6mt with 1335 miles on it and I live in Southern Orange County California, my car has been pinging ever since it was new, yes premium of course, it hardly does it with the ac off but with it on it is worse, I can hear it when I drive next to a wall or a curb with the windows down. I have talked to a few prople and they think it is the quaity of the gas right now, but I havent heard that it is any worse that usual, more expensive yes, but not lower qulaity. There is a gas station near by, I forget what brand, but they have 100 octane at one pump, I was going to try to put a few gallons in to see if that helps but its $6.99 a gal!!!! any input from anyone in SoCal would help, thanks!!

 

bring it to the dealership. you should not be experiencing knock on this car with 91.

 

Thats the first time I've heard of 100 octane in SoCal!

 

some stations sell 102 here for like $6 per gal

i theres one off the 57 in brea and one somewhere in pasadena..

 

its the station on the corner of lapaz and cabot in mission viejo, i forget the name.

 

i hate to change the subject but since I have some SoCal guys here I thought I would ask, is there a SoCal club around here? or meets?, that sort of thing

 

that's a 76 down there... hehe. yea just take it to the dealer. but it shouldn't ever ping. you sure it's not something else?

 

there are some meets that happen here and there... just check the socal forum.

 

Im 99.9% sure its a ping, and its worse with the ac on, more load, makes sense but then again I am slightly paranoid, damn I dont wanna have someone rip apart my new car! my brothers element also pings with 91, he has a buddy at the dealer that said when cars come in for that the retard the timing through the computer, dont want anything like that either, hmm...

 

Have the dealer check the initial ignition timing, and for an intake air leak.
Unless your gas is watered down?????, I'd bet on one of those.

My G was pinging as well. I changed to a different brand last week and it has stopped. Mine was the gas. Sometimes gas can be put in the wrong tank by the tanker drivers. Maybe you got some 87. I think that is what happened to me since I only use 91..

 

Yo! where's the gas station in socal that has 100 octane?? if i put that in will it damage my engine?

 

No but your car might get used to it....its like eating 99 cent cheeseburgers vs. sirloin steak..

 

What's "pinging"?

My '05 6MT engine kind of "shudders" sometimes when sitting at a stop light.. Is that the same problem?

 

I had the same problem. Took it into the dealer. They retarded the timing by 2 degrees. Said it would take far more to change performance. It helped a little but not as much as I'd hoped. So I did the ECU reset thingamajigger and no more ping. Oh, and it feels really fast.
