> go for blaze specially if you have a modded F.I. or N.A. engine.

ano ibig sabihin ng F.I. or N.A engine?

i've yet to try Petron Blaze and Caltex Vortex Gold. naka Velocity kasi ako, and it seems I get good preformance and power. Blaze is a little bit more expensive than Velocity, while Vortex Gold is the cheapest.

i've heard and i somewhat believe that an excellent mix is Velocity and Blaze (maybe 50% of each). why? coz you get the high octane of blaze and the power of velocity at the same time. that mix will have 95.5 octane rating.

thru inference, maybe 50% Petron XCS and 50% Caltex Vortex Gold may produce a different experience.
