This Blue Devil does work
1 of 11 found this helpful Just not this particular size of bottle even though it was recommend for 4-6cyl cars it only work about 10mins after driving it when done following instructions. I have used the more expensive bottle which is twice the size and has a yellow label instead of white it worked excellent for about a month then it had a thermostat housing leak and my husband over heated it and blew the seal again I was just hoping I could save sum money and get the same results but you get what u pay for so get the the more expensive stuff.
