  | I use Blackstone also. Whomever you choose be sure to send a virgin sample of your oil for a baseline. That way you have something to compare the samples to. Todd P

 I believe Paul switched because it was less expensive than Blackstone. With Polaris you do need to purchase a package of 10 pre-paid analysis, but this is still a substantial savings when compared to Blackstone even with the shipping charges. I believe this could be best if checking oil every change. For intermittent checks Blackstone could be a better choice.  |
