14k Maintenance is maintenance though.
I have a 97 Supra with only 13k miles, but I still change the oil once a year. Probably not needed, but it's cheap enough and keeps the car strong.
I wasn't planning on doing anything right away, but I would like to know before I do in the future.
And at this point, it seems that I am not the only one inquiring, and some of which surely have more miles than I do, considering I have multiple vehicles. So going with your logic, at what mileage is maintenance of this sort necessary, and what do you do at such mileage?

 

Thats funny....My dealer cleaned all injectors UNDER WARRANTY according to a TSB for mis-fires

 

Wrong...changing the oil is DEFINITELY needed. Oil changes go by both time and mileage because oil becomes acidic over time, even if the car is not being driven, and it then becomes corrosive and damaging to engine internals and also loses its lubrication ability.

Honestly, IMHO, I wouldnt be messing around by putting any chemicals into these motors unless its absolutely necessary (which it shouldnt be at this point) These LNF motors are tempermental enough as it is, I wouldnt be messing around with them for no reason....not unless youre noticing poor performance or its something the GM engineers are recommending as regular maintenance.

and do you know HOW they exactly went about doing that?

 

Carroll Shelby wouldn't recommend zMAX unless he knew it worked.

 

Or unless he was getting a nice check cut to him for his sponsorship

 

Sorry...travel for work and do not follow all post

This was the best site that brought up the information for the TSB #03-06-04-030F ....

 

Has anyone done that? Seems like a pain in the ass

 

Don't think that applies to Direct Injection engines

 

LNF is on the list...

 

Yep LNF is listed on there.

 

Sounds like a PITA...just saying.
