Auto-Rx in a Jimmy? sludge?

Anybody ever tried this product called Auto-Rx in their engines to de-sludge?

I've got a 97 Jimmy "W" ... no leaks ... 116,000 odometer ... but wondering if it's about time for a de-sludge ... ??? ... just for preventive maintenance ... ???

thoughts? particularly thoughts about maybe only using one bottle to save $$ on the many Auto-Rx recommended oil and filter changes, and still reap a little cleaning benefit ...


Any info would be appreciated ...

Look in the Blazer section, I have posted a thread there on my experience with the product.
