track crew: how often do you change oil?

I run mobile1, and I've done like 8 track-days on this oil, but pressure is still good, oil looks pretty, no oil consumption, and no lifter tick.

I did blow about half of it out on the highway one day when I lost the oil cap, so half the oil is new anyways, but lets ignore this for now.

Thanks for the input.:burnrubr:

I change it before and after each track day.

I change my oil once a month, if I go to the track that month. When the winter season comes along, I'll stick in Castrol GTX or Castrol Synthetic and keep it in there for 3-5K miles. I use GTX because it's cheap and safe. Sometimes I get free oil and I use that, though.

youre supposed to change it! i just thought you added until you can see it underneath the 710 cap.

OK.. I'm confused. I thought you put the coolant in the 710 cap. Have I been doing it wrong?

Oil? What's dat? Is it that stuff dripping on my driveway and burning out my tailpipe?

I'm thinking about dumping amsoil in it, and just changing it every 6 months regardless of the # of track days.

obviously. lol

I'm pretty sure synthetic oil is good for longer than 2 hours of driving. I'm going to send off an oil analysis.

Every 3000 miles no matter what I do with the car. I use semi-synthetic.

Gimmie that dap, pit bull...woof!

The oil is still thick as hell, golden, and not lifter tick. I always though lifter tick was a good indicator of viscosity and lubrication falling off.

But monitor how it looks, level, stuff like that....
