jlomon: Dyno. results can have have been tempered with very easily.
I have also seen TV Info-commercial (DuraLube) where running engines were drained from their oil and ran with water in their oil pan for hours. DuraLube were fined $millions for false advertising based on a test made by Car & Driver magazine where an engine was (honestly) tested using Duralube parameters. The engine self-destroyed in 11 seconds.
Don't believe everything you see or read. If it is too good to be true, it probably is. There's a sucker born every minute.
