This is a great product. Would suggest it to anyone. I put it into my 2003 Toyota Matrix and it made a big difference. My brother used it in his 2010 Legacy as well. Great stuff.

The owner and main Chemical Engineer is Michael Markowitz.
They are based out of IL.
To order, the key things to specify are:
1. Engine type / power level (say 4-cylinder, 160HP)
2. Engine oil capacity (say 4.5 or 7 quarts)
Based on this Michael sends either:
a. Auto Additive
b. Auto Additivie Plus
One is not better than the other, just a different blend for bigger oil fills, bigger engines.
