its true tat caltex techron provides a cleaner fuel, cos techron
acts as some form of detergent n the industry cannot copy it as
they have patent on it..
from wat i heard from other drivers, it seems tat caltex does
provide cleaner fuel, but powerful wise not as good compared to
shell (V power vs Platinum). However, maybe cos of the additive
Shell put inside their fuel, they're more powerful but generate
more carbon residue in the engine..
its kinda common sense to think this way..cleaner fuel, less
powerful..dirtier fuel, more powerful..its up to u to choose..
