cosm3os said:$25. They'll send you the specimen container and mailing stuff. You fill it, stick a couple bucks of postage on it and a week later you have this in your email box. I'll be doing all my driveline lubes.

I would check and see about getting a UOA before chucking the oil. I spoke to a guy who runs a race shop/team at the DC auto show and he said he was doing something similar until he got a UOA and found out he was wasting money changing oil soon.Budget Boss said:Since, my car has just been used on the track for the last 8 months I have change the oil out every 4 hours of track time too. The oil always looks good. However, since the car is just seeing track time now it is best to change the oil as a preventative measure, jmo.
