Was wondering if you had sent out your oil yet?? If not I was wondering how much it costs? Thinking of sending in a sample too.

Not sure on the price, but you pay when you want to see the results. Can't be more than 40$ I would think, either way I'm gonna pay.

I haven't sent it out yet, I went riding for about 3-4 hours on Sunday with my brother in the badlands. Really tight stuff, engine was running at a constant 80-90 degree's celcius and I tried to make the runs about 20 minutes or longer at these temps. I fell a few times, we took a couple little 3 minute breaks, not to sure if that's going to obscure the results as the engine was still very hot before every start.
Anyways, going to go out again this weekend, I'll remember to bring the bottle as the bike is due for a change of oil now. I'll take it for a 20 minute boot and when I come back to the staging area I'll drain, and catch half of the drain in the bottle and send it out asap.
Be patient guys this is happening, work, money and life gets in the way sometimes to slow things down, but I will send this out within the next week or two at the most.

I just made an account to see if anyone ever figured out why this occurs. I have a 2012 yz450f with around 35hrs on it and just noticed this today and found this forum on a google search. It also seemed like I got a lot more oil out of the bike than normal when I drained it. I live in WV and it hasn't gotten that cold here yet and the oil I drained probably had 8hrs on it approximately. I also run Rotella oil. Any information would be appreciated.
