$19.25 at Speedco. I have used them occasionally for a quick check even though I send samples to Oil Analyzers, Inc. the Speedco on site analysis comes in darn close to any sample I have sent to a lab. I have never used Speedco for any oil changes services, but it can be convenient sometimes when I take a sample from my bypass filter. I can swing by, have them run the sample, and get on site results. It can be real handy if you are wanting to keep an eye on something in an oil sample. Having to wait for a sample to get to a lab and get the results is a little discomforting sometimes.
