i pulled a code for p0021 and p0011 the other day, i reset it to see if it would come back, i have a feeling its calling for misfires as well because of my plugs being old.. anyone else have this problem?

 

Indeed!

In a few years I'm sure I will be one of those high mileage guys.

I'm gonna try to get about 150k outta my G. I do about 20k a year. Looks like I'll be car shopping in about 2015-2016. Gonna be some sick cars out by then!

 

I posted this in another area as well.

I rolled 90k today. Syn oil and tire rotation every 7k, 30, 60 and 90k at dealership. New rotors and pads just over 60k, new tires 65k, left front wheel bearing at 53k (warranty), right rear wheel bearing 88k ($590 cash) + the 90k service (OUCH).

I drive over 30k year but was laid off for a few months in 2008 so only 90k in 3 years. Car spends 80% of time at 3000-3500 rpm. 20.8mpg for the 90,000 miles. All that hwy speed is heating up the wheel bearings however. Tech told me hes done 4 bearing jobs on 07 and newer...2 on mine.

Based on economy I may go 2 more years. I should have 160k by then.

Everything great...not a rattle front to back. Couldn't ask for much more from a car.

 

30k a year? Holy hell

 

how many of you use synthetic oil?

are there any advantages to them besides the supposed more miles?

 

I would also like to know since because I'm in need of an oil change @ 87,5xx right now and the car has seen nothing but conventional, should i switch to synthetic?

 

lol you think thats bad i got about 150k on my G 2nd Gen got it at 118k

 

Just to weigh in, I got my 07 G35x with every option 5 months ago with 93k on the clock and its got close to 99k now. I have flushed the trans and diffs, cleaned the throttle bodies(they needed it!). I have also gotten new tires Pirelli PZero Nero All Season's, did an alignment, and also did the brake heat shield TSB, Heated Seat TSB.

Timing chain is called for @ 150k. This spring I need to do plugs and run injector cleaner through it, and take a peak at the timing chain and tensioner. Brake fluid and radiator appear to have been done @ 60k maintenance which was performed at 76k. My dad is a tech and the car appears to have been well taken care of mechanically and had regular oil changes.

 

I use synthetic oil and change it roughly once a year along with the filter.

timing chain at 150k A previous poster said the manual only goes to 103k anyways, glad to hear that everythings copasetic.

 

I bought my 2004 sedan 2 years ago with 86k on it. Now about to hit 140k. No major issues. I have a wheel bearing that's starting to go now. Other than that regular oil changes and had my transmission fluid changed.

I had read the timing chain is supposedly good through 350k. Someone please verify this. Might need a new tensioner? Hopefully don't have to replace the actual chain.

 

+1 some info on the timing chain.

 

I would rather replace it @ 150k then have it slip or break on me while driving down the highway. The chain is 66.87, 3 tensioners at 59.17 each and 2 chain guides one at 15.08 and the other 57.92. for a total of $317.38.

If anything is going to wear over age its going to be the plastic guides and then the tensioners.

 

wow u guys have alot of miles.. im bout to hit 125k in my 03 coupe but damn 110k on an 07.. at 100k i had to change alot of sensors.. i changed all my suspension at bout 110k just cuz of the creaks and noises.. my stock cats blew out at bout 115k.. im on my 3rd motor so cant tell u anything there. but i am on same 5at tranny and was s/c for bout 10k miles

QG35, how did you know your wheel bearings were bad?
