Look on YouTube. They changed the diff oil the tranny fluid and engine oil and dynoed 30 HP more. Look it up.

The dyno doesn't lie my friend. HP numbers tell the story.

Just like Santa is real and no one walked on the moon eh?
If, based on your comments then, you don't believe anything unless you see it right? Well I guess you can't breathe because you can't see oxygen or maybe your heart can't beat because you can't see it?
If you have to see everything in person then you have issues my friend.

i switched to amsoil 0w-30 the a week after i bught my xj with 80,000k on it.the dealer i bought it from just changed the oil with "cheap" conventional 5w-30. i put 1000 miles on it in that week and my average mpg was 18.5 for about 800 miles then started dropping slowly to about 16.5 till i decided to switch it over. i get 20+mpg with 0w-30 even after 20,000 miles on the same oil and filter no drop in milage or performance so guys who say its a waste of money try doing that with conventional oil. the fuel savings alone are worth it not to mention i would of had to change my oil atleast 3 times with conventional oil and the amsoil was only twice as much. i didnt change it until i was just under 30k and still no performance or mpg loss. sent a sample of it and a sample of brand new 0w-30 to get tested and they both came back nearly identical.
