Ive seen other tech doing the piston ring replacement because they show some oil sign all over the piston... Maybe ur is carbon build up, does the VSC light come on? What gas u use? If u use like 87,89 octane gas can damage the motor... These motor recommend 92 and 93 octane.. What yrs is ur car?

 

has anyone tried to call dealer to verify this recall? lol

 

Since it's not a recall that seems like it'd be a waste of time.

 

I wanna try putting 100 octane in my car

 

Great way to ruin your catalytic converters since race gas is often leaded.

If it's unleaded then it's just a great way to waste $ since the car is programmed for 91... anything higher won't do anything for you at all but cost more.

 

I'm aware of that
Putting racing fuel in my 250 is just retarded

 

amir, did the new pistons/piston seals/rings fix your carbon deposit or stuttering issue?

my wife's car's stuttering. we already had the top engine clean once, but it came back.

 

sorry been away from the comp for a while. i believe its for is250's and its for the years from 06-10 but i dont know the details got to ask my friend. but its something to do with the pistons. could be rings could be seals. but its something he said hes dealership has him working on ALL day.

 

Yess. Thats the exact issue i was having so i brought it in. They pulled up some error codes i have to check what they were exactly. It didnt trigger a light in the dashboard. But its been running great.
