I've top up my gesoline in Johor bahru in past few weeks.
and I've found that gasoline run out very fast, it seems
10-20% faster than Singapore gesoline. I'm not sure whether
it is due to the vendor change the meter, or my bike engine
has it own problem.
In the other hand, I know that in China, some gas station
put some chemical material in the gasoline, so that it will
sold in higher price, like 92 can changed to 97, but this
will
demage the carburator of some cars and bikes. (Not all)
Does anyone have the same experience to share? Which
gas station brand is trustworth
