hey guys! no posts for a while (i never posted that much anyway-more fun to sit back and read). i am doing my first analysis and ordered the Blackstone/Dyson kit on Friday. It got here today. No qualms about speed from Blackstone yet, but I did prepay. I would like to do this right and there really are no "instructions" enclosed-OK this shouldnt be rocket science "smeltboy", right?? however i do have two questions. the first is that i was sent TWO sample bottles (maybe i paid for two when i only asked for one. geez you also figure they could have return postage for $35). do TWO samples need to be sent in with each analysis??? if not, why two bottles?? also these bottles are PLASTIC. any concerns of these melting with HOT oil going in??? FYI, this is on my daily beater, 90 acura integra, 130K with a "soup" that i'll be somewhat embarassed to admit-unless it turns out good. most of it is Schaeffers, though. we'll see just how shot the motor might be, even though it still runs great. thanks.
