I've ordered Amsoil too, waiting to change it during my next servicing...currently still on TCM Fastflo, how's the diff using Amsoil? Smoother response, etc? 
Hi all,
I bring my own Amsoil 0W30 for my 10,000km servicing. No service charge. Brought 4 bottles, used only 3 bottles and return me the remaining 1 bottle.
I must say AMSOIL is good, after reading good reviews here in this forum.
Wanna know why i say good?
Normally, from full (at the brink) to first quarter mark will clocked about 120km.
After using AMSOIL, i managed to clock 130km++ a whooping difference of 10KM!
Driving pattern still same: 80% highway 20% city. Quite light footed, rev till 2500RPM from stationary when moving off.
Normally i pump Esso 5000. But after servicing I pumped Esso 8000. I dunno whether Esso 5000 and Esso 8000 unleaded got diff in my FC variations.
All I can say engine now more smooth and more responsive, with better FC. Just my 2 cents.
