Hi all,
I went to do an emission test, but the '88 Brougham fails. It shows over 300 in HC ppm. The emission facility mechanic suggested to use guaranteed-to-pass-emissions-formula.
I heard that seafoam can help also. My question is that the car was sitting for a year with a full of tank, and I just purchased the car two weeks ago, so I need to pass the emission to register the car under my name. I am wondering if I put guarantee formula with already old gas in the tank would that work?
OR shall I empty the tank for driving long trip, then put fresh gas in with formula?
I also wonder if I can use seafoam in conjunction with the formula?
Your advice will be very helpful.
Thanks,
