Wearcheck is definitely your best bet. I had two samples recently where I dropped them off first thing in the morning at the lab and they had my results for me by 4pm the same day!
For great cost, I dont know about how fast service is because I have to send my oil samples to Regina due to my rural location. Kramer Cat does an oil analysis for about $15.00.
