Fluids for the track car..... what do you use?
As I'm setting up my C6Z as a track only car all the fluids that would otherwise worked on the street more than likely should be changed out. What do you use and why (brand,weight,compound etc)? What are the recommended change intervals on the different fluids with a track only set-up. Do you go by hours,miles,events,what?
Thanks in advance for your input

I change the oil by the life monitor, the trans and diff before every season. But I run TT so we don't see a lot of laps, but the laps we do run are........flat out.

For track use, I run 15w50 for the engine, synchromesh for the tranny, don't remember for the rearend but I think it's 75w140 or 110. I know that's what Jerry Onks runs as well when he is racing his STO C6Z.

I use all Mobil 1 synthetic fluids in my 03 Z06. M1 synthetic ATF in tranny, M1 75-90 Gear lube with the GM posi additive just in case, synthetic power steering fluid and M1 5-30 for the engine. Change out trans, diff and PS on an annual basis and engine oil every third event or when DIC hits 50%, usually every third event. Been tracking for over 5 years with almost 10K track miles and knock on wood no problems yet.

Diff: Amsoil 75-110 Severe Gear
Trans: tried several, they all have drawbacks but Redline D4 works well for many, but is a bit thin at high temps for me
Engine: Renewable Lubricants Inc (RLI) 5w-40 HD. Stands up to more track events & gives me lower wear readings than anything else I've tried.

I've been using Motul RBF 600 for my C6 Vert when tracking it with no fade issues. Keep in mind the with the vert I'm only running hi-speed 15-20 min. at a time with 30-40 min cool down time between
What makes the Castrol SRF better... do you get more use time between changes or longer track times with out fade issues?
Thanks

I have spent less money with SRF than anything I else I have used. I do a flush before the first event of the year and bleed once around the midpoint of the season.

I run amsoil fluids in my diff, trans, and clutch. I run german castrol in the engine but will soon switch to amsoil. I run motul 660 brake fluid which I'll soon replace with castrol.

For clutch, I use Amsoil 600 since it needs to be changed every event to get rid of the clutch dust in the fluid and it has a very high dry boiling point.

RedLine 40W race oil in the engine
RedLine D4 ATF in the tranny, extreme duty cars I'll mix in one quart of MTL
RedLine 75w90 Diff oil
Castrol SRF brake fluid
If you do dual use with the car, I would run Mobile 1 or RedLine street oil through the engine during off season use to keep the inside clean.

The Motul is more hygroscopic and will therefore need more frequent changing. The single advanced feature of Castrol SRF is the way it handles moisture. Not only is the dry boiling point high, but the fluid is less hygroscopic, and what water is does absorb is trapped so it doesn't boil off or rust your braking system, so it can be left in all season offsetting the initial cost (and thus also has a very high wet boiling point)...
BTW, where's the best deal on it (not in bulk quantities) you guys have found?
