I've seen first hand properly maintained engines in sound mechanical condition need an engine cleaning product or flush. I posted pictures a few years back of a 2000 Buick Century I was given by my father. He owned it since new and had religious oil changes done every 3K miles or less with name brand dino oils. The top of the engine was far from perfect with about 80K miles on the clock. FTR there were no problems with the lower intake manifold gaskets, the engine was mechanically sound. I'm not an Amsoil fan but the info posted from them about doing a flush can have merit, even in a well maintained engine. I'd opt for something along the lines of Rislone, Kreen or MMO, rather than a fast flush.
This can make one wonder, did dad do his own oil changes? Or was it possible he fell victim to one of those places that don't even change the oil? Very weird to hear of a vehicle serviced every 3,000 miles and not look good inside. Did he take a lot of short trips?
When the vehicle was serviced, Pop often watched the local shop or dealer do it. If he didn't watch he popped the hood and checked to make sure it was done, it's a NY thing. LOL Now that I think of it my brother might have serviced it a few times as well. The vehicle was driven under L.I. NY driving conditions which usually suck, with quite a bit of short trips. That brings me to another point, which I ruffled a few feathers with from time to time here. Blanket statements written here can get people in trouble. Had he followed the a good dino oil can go 5K miles and synthetic can go 10K miles would have spelled disaster for the car.
