Guaranteed to Pass Emissions Test Formula (12 oz.)

Live in NJ where we have very stringent emissions testing, have used this product 3 times in the last six years, same car now with 140,480 miles on the clock and readings were about 40% of what is allowed, follow instruction on the box and you got it.

My mechanic recommended this after barely failing the smog test. I ran a gas tank through, filled up again, and returned to the test station. Sure enough, it passed!

Buy it, read the back and pass the test.
