Just added 12 ounces of Biotech to the Corolla. My main reason for testing is to see if my mpg improves. I added it to Formula Shell 5w30. I'll also provide any anecdotal experiences as well("smooth", "quiet").
My last three OCI mpg's have been 35.5/34.5/37.2 respectively. I will be comparing against the 37.2 though as that OCI is the same conditions as this one will be(no a/c use). There is one difference though; which is the oils used. Schaeffer's 5w30 w/ the last OCI and Shell 5w30 w/ this OCI.
I also added 6 ounces Lubegard Red to the transmission and did a drain/fill w/ Maxlife ATF.
Doing this because I'm curious and because there isn't much on this additive. I will be able to update soon since I drive an average of 1,000 miles/weekly.
