Just a comment on your method of sampling. Going through the dipstick tube will most likely contaminate the sample. Warm up the engine and then pull the drain plug as soon after shutting off the engine as possible. Take the sample from the main stream of oil. You must keep in mind that these samples are talking ppm so any minute contaminant will affect the outcome.
