Additive can really feel the difference? I added additives usually when I'm going outstation
since it was recommended for fuel saving. It was yellow in colour. But dun feel much
difference with or without it.
I pour it into the corolla. Can use 3 times. Stop buying since then.
Got from a friend who let me try it first, to see if can run. As you know I able driving old school turbo and requires Ron97. Tried Ron95 and it knocked badly, to the extent cannot rev past 4.5k RPM. Now with this additive can run, so just keep using....can rev to red line without problems.....
