hydraulic clutch fluid
today i when i was at the dealership dropping my car off for warranty work i was talkin to my service advisor about my clutch getting really hard in high RPM's
Area47 thinks its after market clutch or i got air in the system.
well my advisor told me that chevy recomends the hydraulic fluid to be changed ever 15-20k.
anyone else know about this at all?

According to the maitenance schedual in my Haynes Manual for GM Chevrolet Cobalt & Pontiac G5 2005 - 2007 All Models
It recomends changeing the brake fluid ever 30, 000 miles, or 24 months.
The brake fluid being the same as the clutch fluid.
My Chilton's manual covering the same cares also has the same recomendation
My owner's manual does not give a change interval.

GM is unique (and wrong imo) among manufacturers in that they do not recommend servicing brake/clutch fluid. Virtually every other maker has a service interval of somewhere between 12months and 4years for replacing brake fluid(2yrs is common) and this is a good idea and very necessary.
brake fluid is hygroscopic, which means it absorbs water, and can absorb it directly from the air. Its supposed to do this, by absorbing it and spreading it throughout the system it virtually eliminates the chances of pools of water forming(this would be very bad) but this also means that eventually the fluid becomes corrosive to the brake parts and and once it absorbs water, its ability to withstand high heat degraqdes, IE: the fluid will be able to "boil" at a lower temperature. So obviously a corrosive fluid that may boil is a real bad thing. Thats why you need to flush your brake/clutch fluid.
Getting a flush with any fresh DOT3/4 fluid once every 12 months is a good idea.
Getting a flush with a high quality, high "wet boiling point" DOT4/5.1 every year is a great idea.
IMO your first flush should be 12 months after you get car if its new, if its over a year old and used, do it immediately. After that first flush, once every 2yrs is perfectly fine if you use a high quality, high wet boiling point fluid, I use ATE Typ 200 (Super Blue is same stuff) in virtually everything I can. Great stuff, high boiling points, comes in metal can(you can store it for a while without it absorbing too much moisture) and its cheap its readily available for under $15/liter
Moral of the story......get your brake/clutch fluid flushed.
