Paul, How true! For the mileage that most of us drive our old Imperials, platinum plugs wouldn't pay, if they didn't cause problems. Part of the reason I asked the question is that for my daily driver, an '87 Mercedes 560SEL, platinum plugs are NOT recommended at all. Standard, heavy copper plugs (in that case Bosch is the preferred but Champion and Autolite make comparable plugs) are the only thing that will work. I've actually stuck with the Bosch as I can get them online for less than the others. Thanks again to all for the input and interesting discussion. Right now some brake work and general rewiring are at the top of the list for the winter. A tune-up may be in order come spring, however.

The thing is, there is little point in spending the money for a long life spark plug in a car that doesn't burn fuel efficiently enough to get the benefit. The spark plugs in '50s and '60s Imperials are suppose to be changed every 10-15,000 miles. Newer cars can easily go 60,000 miles between plug sets, so that's why I purchase the higher price plugs.
