Hey Guys,
wanted to know how often you change your oil and brake fluid for the track?

I was just at Thunderhill yesterday, and the guy next to me, with an 09 848, he changes his oil every 2 trackdays, with synthetic oil no less.

so how many trackdays till you change your oil and brake fluid?
I justed started to track my bikes (have a cbr 1000rr 2011) maybe 5-6 days a yr, most days on the zx6r (more fun on the track).

Even though I'm a gal, my dad taught me to do my own maintenance on cars, and it's carried over to bikes. I keep an eye on oil and all the fluids, of course. I only ride 6k-7k miles a yr. and I'm not good enough yet to flog either bike on the track.

your thoughts are appreciated.

thx in advance.

I do every 4/5 trackdays with full synthetic as well. Brake fluid is about the same. For a year or two, I did every three trackdays but sometimes the oil looked barely used.

I'm about to send my oil in for analysis. Amsoil with 7.5 (0.5 is an instructing day and 8ish runs on a drag strip) track days on it at a solid advanced pace. I'll let ya know.

Brake fluid...I'm more lenient about. I usually do once a year but I'll probably start doing twice a year...which reminds me that I need to buy some for my upcoming race. Depending on the climate and how fast you are, once a year maybe fine, twice a year would probably be more beneficial, and anymore than that you'd need to be extremely fast and/or live in a really humid climate.

What level do you ride at?

About 4 to 5 track days myself. I normally use Motul 300V full synthetic. Brake fluid I'll let go a little longer. bRiT is right, I changed my oil once after 3 track days and the Motul 300V was still green! I wanted to put it back in the bike to save the new oil for later

I had the same experience with the Motul! But i actually wanted to get it out of my engine, my bike didnt like to shift as smooth with it.

I just started to track my bike this summer, and riding for 2 yrs. but I have a track prepped car, and I've been tracking that for 5 yrs or so, and a graduate of skip barber racing school (3 day). I'm a low B+ but prefer to ride B- for now. never kept time, but the guy with the 848 next to me, he used to track cars as well, and he's a B+/A- rider, but was in the B- group with me, b/c a bunch of his friends were supposed to go, but no showed.

Anyway he followed me for a few laps one session and kept lap times. so that's how I know I'd be a low B+. honestly I'm just working on lines and initiating turns correctly, as well as accelerating out of the apex, and threshold braking.

I will work on my my body position at my next trackday, aka getting a butt cheek off the seat. I don't really care about dragging a knee, I know it'll happen eventually. I might have to raise my rearsets again, so I can keep the outside foot anchored.

is amsoil brake fluid that much better than motul 600 or motul 660?

Glad to hear you are progressing, great job!

Id change it every ~1200 track miles. Thats like 6 trackdays at my local track.

I'm lazy and use more expensive ATE super blue DOT 4 brake fluid. I don't buy it for performance spec, i buy it because its easier to see air bubbles while bleeding. Honestly, buy what ever DOT 4 brake fluid you feel is best. They all have very similar braking characteristics

This! Except that I wouldn't do that with the "lighter" versions of the 300V (i.e. 5W or 10W). With those I'd change the oil after 3 track days max...

I currently use the 15W and it even after 5 days you still have the oil smelling like bubble gum (or whatever that is) and it's nowhere near burnt out.

Brake fluid is a twice a year affair in most cases. Just remember that higher spec fluids (5.1 etc) will absorb moisture faster and will require more changes... especially if you leave the bike in the sun or in a very humid place (my garage is like the batcave so 3 times a year is still pushing it).

I change my oil every other track weekend. Brake fluid depends on how the brakes feel and I usually just bleed them after every weekend and top off. Excessive maybe, but I love the feel of fresh bled brakes.
