My '01 LeSabre has 97,000 miles on it and has always run quite well. My driving is 95% highway milage. As with most of you, I want to keep this car for as long as possible and make sure its running at peak efficiency. I have been using Lucas UCL for about 6 months or so. (Its hard to determine effect on milage b/c of "winter blend" gas up here in the perpetually frozen north).
My question is whether I would derive any benefit from using Sea Foam. I have read up a little on it, and must admit that the idea of putting the same product in the crankcase AND gas tank strikes me as a little "weird". (I don't think that the Lucas folks would advise me to pour 1/3 of a bottle of UCL in my crankcase).
Have any of you switched from Lucas to Sea Foam? Has anyone analyzed what the heck its chemical composition is? Is it worth it? What can it do that Lucas UCL can't? Can I / should I use both ? I think that my 3800 is fairly "sluge free" but do not want to start pulling of valve covers to see. ["Sludge Denial Syndrome"] What is the "least invasive" way to check my "sludge factor"?
