Man I like that stuff
Some minor and ongoing testing reveals it burns clean , clean clean
based on my use
About a year ago I had a GM car that the solenoid for the overdrive was locked . Poured some 131 in and it fixed it too . I have never drained it out .
Works good for a gentle purge about 500 miles before oil change like recommended on the label . I have ran it the entire interval in one old V8 .
It does so many things and is low cost .
