Hi Guys,

I have a 2008 G35S with only 9k miles on the ODO. I started using the German Castrol synthetic since the car hit 5k. I just did an oil change 100 miles ago with the same oil.

I am noticing that the car tends to vibrate while I am stopped at a light, regardless of whether the ac is on or not. If I move it N it does the same thing. Any one else experiencing this? Could this be bad gas? or Carbon build up?

I was thinking of adding a bottle of Sea Foam to the remaining half tank of gas... What do you guys think? Vibrations are not bad and you have to pay attention to fee them but they are there. Almost feels like a cough.

Please Advice!
Thanks

 

I think the seafoam is for sludge. I doubt your 9K car will have that. Have you checked your oi level? If everything is OK, then I would say it's the gas since it's too young to have spark problems. Don't know where you drive but you can also check the air filter.

See if it's still there after a couple of tanks from a different station.
