Resurrecting an older thread, but the only complaint I have seen with Blackstone is their method of testing fuel dilution and cost. They use a flashpoint test to estimate fuel dilution https://www.blackstone-labs.com/what-is-a-flash-point/. Other labs use what are supposed to be more accurate methods (gas chromatography, I believe) and get different results. This may not matter to some or on most occasions.
I'm about to post a comparison from Blackstone and Oil Analyzers/Polaris here: https://www.expeditionforum.com/threads/oil-analysis-results-0-5k-and-5k-10k.45610/page-2
