High mileage 2001 LS6 performance test
Yesterday i decided to run my 01 ZO6 AT Capitol Raceway. The more miles i put on this car the faster it goes. My ZO6 has 77,850 hard driven miles and is completely stock except for the twin cone air filters. If anyone has questioned the durability of the 385 hp LS6, hopefully yesterdays run will put those concerns to rest. To my surprise the car went 12.446 @ 113.99 mph (best run to date). The 60' was 1.922 on the stock supercar radials. I congratulate GM on building one tough high performing engine. You can see pics of my car at the track getting ready to run the 1/4 at capitolraceway.com The picture # is IMG_8312

Awesome... I have just over 55k on mine. But I had to have mine re-ringed... and the dif leaked, and the trans leaked at the rear, and now it's seeping at the front! Oh and the rear main seal leaked a little.
However I run HPDE in the car... and I'm meticulous about maintenance.
GM warranty (extended) has fixed everything, but I think I'm going to try using good RTV on the front trans seal instead of wasting time in the shop having them pull it all out again.

The engine has has never been apart. There are no leaks from the engine but it does like to drink the mobil 1. I have to add a quart between oil changes. The only problems i have with the car are sometimes the fuel gauge doesn't work properly and the clutch pedal likes to stick to the floor under hard acceleration. Overall ,with the performance this car delivers, i don't complain about the few problems it has. Nothing relieves stress like banging some gears while prowling the streets hunting for SNAKE (THE OTHER WHITE MEAT) and RICE !!! This car was built for one thing and i bought it for one thing, HARD DRIVING.

ZR1 baby!!! 122k and 395 rwhp and still pulls strong. Drinks a quart in between oil changes but ZR1's do that.
Looking for a C5 soon to add to the collection. Nice to hear it will hold up!

The 02' "Z" I bought a couple of weeks ago had just turned 70k on it. The car checked out perfect before I bought it, clean, no leaks. Reading all the posts on reliability on these cars helped me make my decision to go ahead and buy the Z with that much mileage. Hopefully I can put another 70k on it without any major work.
