I used Motul 600 in my 462 and had it decoked before selling it. It was as clean as whistle.
Motul is Ester based meaning its made of the statically charged particles the Castrol Magnatec has a few of. Motul is over 40% of this stuff, Magnatec is around 4%.
I've also used Comp 2 and both of these have excellent dies to help show how much fuel is remaining.
In the biking world there are only two brands used by enthusiasts... Motul and Silkolene.
