I can recomend either Royal Purple .. if you wanna spend a lil extra

There was an oil that i had in the UK (not sure about here) it was called ZX1 and i actually did a little test of my own... and i have to say the lubrication was about 5x better (no exaduration). The oil actually bonds with the metal making it extremely hard to get metal on metal contact. I used Shell premium synthetic oil as my other test subject and soaked some parts in oil... and the ZX1 was really hard to penitrate.

If you look online you might actually find a video about it... its common

 

can you buy that stuff here in the states? if you do use it do you get the same problems you get when going from synthetic to regular oil?

 

Ive heard of this stuff before...
