Definently keep us all posted. Over at BITOG forums I've been skeptical but impressed at the before and after results. If this works well for you I'll probably seek this out myself this summer as I close in on 100000 miles on my 2000 LS. I've also got a 2000 Grand Voyager SE with close to 100000 that I'll try it on too.
MY VEHICLE MAINTENANCE DEPENDS ON YOU BLAZER LT!!!!
