I come from China.For my vehicle,a mazda axela 1.5l,I think TOTAL works better than CASTROL,especially for less fuel use/better smoothly accelaration/more queit.only FOR tough driving conditions(like going into 180kpm),EDGE WILL be a little better.BTW,in my country,TOTAL 9000 is 40% cheaper than EDGE(32RMB /50RMB).
NEXT TIME I WILL TRY pp0w20.IT maybe awsome .AHA.
