Problems after 200,000 Miles

-ECU died after about 6 months, warranty no biggy other then the down time.

-CSC, went through the original one at about 135,000 miles. (since then I've had to do the CSC 2 more times, the first time it was done I changed to a Stillen flywheel and ACT clutch, it was too much pressure for the OE CSC so I put the OE parts in and it's been good. The dealer even covered them this time, had the master done each time as well.)

-SL went about 150,000 miles, before the recall, got reimbursed after the recall and another one put in, just so they could say it was done and I had the newest version.

-Front hubs, cant remember when for sure, but about 150,000 also.

-Fuel sending unit had to be changed a couple times also, both under warranty, not reading full.

-Fuel Prefilter dirty causing loss of RPM at about 175,000 miles, I pulled the pump unit out and cleaned it, been good since.

-Paint wise, I have a couple paint bubbles starting, as I do drive the car all year round in Canada. As well the usual stone chips, which I try and fill as soon as I notice them.

Oil changes with Redline are every 4500miles, (i'm down about a quart each change) full fluid change every 60k with Redline oils also. Plugs and drive belt (accessory belt) if you prefer done every 75k.

Try to run only Shell premium fuel also.

If you have any questions let me know, if I can think of any thing else I will add it.

Thanks and keep driving!

Just wondering if the oil consumption increased at higher mileage or it is about the same through out the 200k miles?

How about the transmission? Did the shifting get worse?

while it is normal for our Z motors to use a bit of oil even at low mileage, i have heard some honda engines do not burn any oil even at 100k miles.

BTW, "some" Chevy engines do not burn any oil even at 100k miles. And "some" Ford engines engines do not burn any oil even at 100k miles. And "some" Toyota engines... 'Ya know?
