Of course, I have an issue.
Well, not really, but you kow how it goes.
I work very hard to learn, with many resources not available to most. Well, they're available, but most aren't spending the money on them, so it's the same thing.
Most is a cheap sucker.
I sometimes see issues with carryover at my corporate lab. And they don't have a conveyor feeding the ICP, particle counter, or viscometer.
So that rings very true.
I get 2 kinds of reports. Raw data only, which is a heck of a way to learn, btw.
And results personally interpretted by folks trained personnally by one of the giants of the industry.
I don't send them car stuff though. Because it's not worth the money!
Well, except for that once when my wife decided to let a shop change her S60R's oil w out watching.
As for extending drains, yes, I'll do it in select cases. Non warranty and RULER backed, because I can do those cheap, I understand the limitations, and I am not relying on some drone to tell me what to do.
Lamont, you really ought to be patentable.
There, I just established my claim!
