Observations of a Hi-Perf. Car Newbe :)

Changed my engine oil, transmission oil and differential oil this past weekend. I am so glad I did.

Only 5K miles and sure I drive her like she was meant to be driven but never raced yet.

1) Engine oil no real problems seen
2) Transmission Oil had a real burnt smell to it and was a dark red in color with some particles observed in the fluid.
3) Differential fluid was full of metal flakes :eek:

Also installed magnetic drain plugs into all three.

Noticed what I can describe as an increased "smoothness" and much smoother shifting with the new fluids.

Bottom Line - IMO I would definitely not wait until the General says it's time to change the fluids. :roll:

Hello pdx_Z

I have been told that they are suppose to help catch and hold metal particles from recirculating again in the surrounding fluid.

First time I have tried them so we will seeif they work. :D

I just rolled the odometer to 3750 miles. Our driving experience and styles are very similar. I am going to follow your lead and change my fluids sometime in the next few weeks. Thanks for the great post. :cheers:

Don't forget "cooked" clutch fluid

You might think about maintenance of the clutch hydraulic fluid too. If you run the car fairly hard, the fluid gets "cooked" and causes the clutch pedal to behave badly.

Check the fluid in the reservoir under the hood. If it's dark brown and full of black bits, then changing out the fluid in the reservoir at regular intervals will help. So will upgrading the fluid to DOT-4 vice stock DOT-3. They are compatible and can be mixed. The hydraulic system holds about 16 ounces. The reservoir holds only a couple. So a complete change out via the reservoir occurs over time. Another alternative is bleeding the clutch. If you do that, run an entire quart through. The procedure cost me about $115 at a nearby Corvette-only shop. But avoiding clutch issues should involve regular maintenance of the clutch fluid. Neither the dealer nor Chevy acknowledge that cooked clutch fluid is a root cause of clutch issues. They are wrong.

How much...

What can I expect to pay to have all the fluids changed, at my local Chevy dealer? Am I nuts? :-? :-? :-?

Change the OIL!!!!!!!!!

Clean Oil is GOOD.
Oil is relatively CHEAP.
If Oil just STARTS to look dirty on the dipstick, I change it and the filter, normally at about 1,500 miles.
The transmission and differential are normally annual changes for me.
These fluids are the lifeblood of your car.
GM tells me I don't have to change them this often, but I feel good that I do.
See ya.

It isn't the price. My dealership charges $12 if I bring in my own oil and filter. The problem is: on all C5s the commercial places don't allow enough time or the correct angle for ALL the old oil to drip out. These cars take a good half hour, with the rear slightly elevated, to properly drain. When they do it, your car will only take 6 quarts of oil and when you do it your car will take at least 6 1/2 quarts.

I changed my oil at 1,250 miles and was really surprised at how dirty it was. It's tough work to break a Z in! I always change the oil before winter storage and even though the car was so new with little miles on it, I'm glad I stuck to my principles and did it. Now I'll have it all ready to go in the spring so I can just get in and drive. I can hardly wait!

Hello All.

Yes, I have also been replacing the clutch fluid (as much as I can pull out of the reservoir when I notice any discoloration).

For a differential magnetic plug I was able to get one from a catalog supplier.

MOST IMPORTANTLY - Refilling the trans and differential fluids. I purchased what is called an Evacuation and Dispensing Pump that worked awesome! Just filled it up, crawled under the car, placed the hose into the opening and slowly squeezed until it was full. Very easy and no mess. :D :D

PM or Email me if you want more info.

Thanks, Rollin.

Now that's the way to do it!

Regarding x-mission fluid changes

Quoting c4c5specialist from a previous post when I was considering changing to Redline D4 ATF with 1400 miles on my Z06:

"...it may take up to 5000 miles for the syncros to bed in correctly due to the composition of the inner and outer cones within the syncronizer assembly. As for the fluuid, I would really allow the trans to bed in first, before attempting this fluid change."


Also, c4c5specialist recommended 15K miles before changing the diff gear oil.

Great point 02BlueZ06.

That was the main reason I waited until I had 5K on the clock :D

I did not want to wait 15K miles prior to changing the diff gear oil however and I am glad I didn't wait after seeing the stuff.

Thanks for the very important point about the tranny :cool:

I ordered one also. All my evacuation gear is getting old and the only unit I have left in good shape is my MightyVac for brakes. This unit from Griots Garage looks like the right number to work with under my new kwicklift drive on ramp. www.kwicklift.com

I changed my engine oil/filter at 500 miles on this 02 Z06. I could see the cam lube and other additives in the oil. Was surpised GM didn't have a magnetic plug.

Thanks.

The lift took about 30 minutes to assemble (alone).
8 bolts/washers/nuts a couple through rods and it's assembled.

You need a good floor jack to raise the car up and rear lift supports are spring loaded (bolt action)and will fall out when needed. I have a 2 1/2 ton jack under mine to lift it. Plenty of room. I used an old plastic waste can (kitchen size) to change my engine oil. Just put it under the pan and left it. No mess. Plenty of room.

One thing you have to keep in mind, when I picked up this unit it was heavy and on a pallet. You need a truck as you will have to pick it up. They ship the units to a local shipping place near you.
Mine was AAA shipping a local trucking outfit.
