However, if I drive 100 miles a day/5 days a week then I don't see any reason to change the Amsoil. Even if I did not hit the 35,000 mile limit, I should be able to keep going past one year. (IMHO)

quote:Most manufacturers recommend changing the brake fluid every 2 years. The coolant schedule may be different for different makes of vehicles. Conventional coolant is replaced every 2 years; "long-life" coolant every 3-5 (Ford is 3 years/50,000 miles, GM is 5 years/150,000 miles), and some European brands utilize lifetime coolant.

quote:There are a lot of guys in my car club that are into autocrossing and road racing, and every single one of them recommends changing out the brake fluid every year. Even on a normal street driven car they say it should be done every 2-3 years. I noticed better braking on my 97 GTP when I had it's brake fluid flushed (this was in early 2001, so the fluid was at least 4 years old)
Originally posted by Mike: What kind of vehicle are you talking about with a vent hole in the M/C?. I just looked over my 4 GM vehicles (92,93, 01 & 02) and if there is no vent, there is a air tight rubber seal. I spoke to a ASE (20+ yrs experience) brake man this AM (my 92 K1500 needs new rotors etc) and he shook his head when I told him some were advocating changing brake fluid every 2 yrs. No need to change brake fluid unless there is contamination present.
quote:Coolant is composed of additives as well to protect the engine. Yes, coolant needs to be changed. For the old ethelene glyco green stuff about every two eyars after the first change and for the dexcool, well they say 100,000 miles or 5 years but I woould opt for three to plkay it safe. Amazing how much crap drains out of the radiators after 3 years.

quote:It's definitely a scheduled item for my Honda. I think it's on 2 year/30,000 mile schedule, but I'm not positive. When I changed my brake fluid last year, I don't know how long the old stuff had been in there. At least since I bought the car used three years before. The fluid was dark, slimy, and viscous, not at all like the new fluid. I don't know for sure that the transformation would affect performance, but it was obvious that it wasn't the same as new fluid.
