Ok, in my quick google search, I found a comapny, EliteETC.com, that if I read it right, looks like they can analyze oil for $15. Google baby, Google! I love Google. Quick story, off topic, but when I was looking at XF's to test drive/purchase, the sales guys always tried to pressure me into buying their cars. I always told them, "Look. I'm not buying a car today without further research. My last BBQ I bought, I researched for 8 weeks before making a final decision, I'm certainly not buying a car without more research on your car". Ok, back to the subject at hand. TY. LOL
