I haven't used Seafoam but my mechanics at the Honda dealership where I work
do recommend it. I have used Marvel Mystery Oil and ran it for 1000 miles
in the crankcase before an oil change. I normally use Mobil 1 for 6,000 miles
and replace the filter (Mann/Mahle) every 3,000 miles. I was surprised to see
the color of the old oil that came out of the engine after running the
Marvel Mystery Oil-much darker than after any other oil change. It did quiet the
engine's lifters somewhat and no oil leaks developed from possibly removing
some of the sludge. It had been 60k since my rebuild with nothing but Mobil 1
after engine break in. I am assuming that the sludge was old from engine oil
passages that were inaccessible or components that were not replaced or cleaned
during the rebuild. There was discussion of other worthwhile additives for
the fuel system. I had previously used only Techroline (Chevron product) and
had been fairly satisfied that it did what it claimed to do. My best results
were with a product (line of products) that is available at many auto
dealerships in my area. It is from a company called "BG" and is the fuel injection
service. It is a two part cleaning. An additive that goes in to the tank and a
aerosol from a liquid that is delivered via compressed air to the intake at
the throttle body. I added this myself at the dealership followed by a manual
cleaning with a brush to remove any stuborn carbon deposits. My idle smoothed
out and dropped 50-75 rpm's. I do not think that there was any significant
build up of deposits in my case as I believe in using a good quality, name
brand fuel with a good amount of detergents. I have seen, all too often, the
problems caused by cheap gas (clogged injectors, dirty plenum and throttle body
and clogged EGR ports). Really, the savings on cheap gas is short term in
most cases when you factor the lost fuel economy and repairs/maintenance that
you will face in the long term.
