I purchased 3 of the NAPA #4077 oil analysis kits about a year ago. I paid around $15 each for these and it includes the bottles, submission form, labels and the actual analysis. I broke one open this weekend to send in a sample from my diesel Silverado and as I was filling out the paperwork, I noticed a line on the top of the form that said "Expires 10-30-2011"! WHAT? My prepaid oil analysis expired? On what basis can they do this? I filled out the form and sent the sample in anyway. I hope they do the analysis. If not, they are going to have to write a lot of letters responding to the BBB, Consumer affairs, Yelp etc....
