We would like to add that each of our formulas has as many as 12 chemicals. Bio-Diesel is just a small part.
We took samples of all our base chemicals this morning and none of them had any contaminants whatsoever.
There was a point where Opti-Lube was run from a garage when it was under control of another owner. At this point, it is part of Low Range Off-Road and has part of our facility in Utah.
If anyone finds this in the bottom of their containers, please call us for a refund or replacement of product.
