      I think it refers to winding out the engine on a highway to try to clear out any crap and get the engine running better without having to pop the hood. No idea where the name came from.

      Something that occurred to me is that you might want to look at some YouTube videos dealing with sludge to get an idea of the extent of the problem you might be dealing with. I happened to see one a little while ago in which they took off the valve covers and vacuumed out lots of goopy sludge. I just had a look-see and saw one with sludge that was like a thick dried mud. I would guess the big concern would be clogging up oil passages and depriving critical components of oil.

        basically put in D (3rd) and drive it up to 70 on the highway for a while. Helps blow out the carbon buildup in the heads and will get the temps up everywhere to melt off the sludge and get it moving. May take a few runs to get it all out (with oil changes between). I would just run clean oil and watch it. When it gets dirty, change it. If that takes 100 miles or 1000 miles or 5000 miles. Which is why I like the auto-rx method.

          Another possible thing to consider is whether you do oil changes while the oil is still warm. I don't know to what extent draining warm oil would be better than draining cold oil, but every little bit helps.

            I was trained to warm the car up completely and then drain the oil and remove filter. Hot oil does drain more effectively even though your hands may not like the idea!

                I agree. Several long-distance trips with oil changes in-between would be good.

                  I beg to differ on the seafoam route.

                  I used seafoam for my brothers vic 87 tudor and my 89 town car

                  I don't pour in the whole bottle, I just pour in like 3-5 cap fulls (caps being the cap that comes with the seafoam)

                  It definietely comes out a lot darker then when I use the dipstick and it seems to run a little smoother.

                  I would use seafoam, JUST DON"T POUR THE WHOEL BOTTLE IN, USE IN MODERATION
