Maybe switch to Vegetable oil, if you really cannot
tahan....
I am serious, 2 years ago, I think some country ppl started using
veg converted oil for fuel...but kena banned, cause it was hurting
the petrol industry....
Aiyah.....the fuel saving devices all don't work one la....don't
waste your hard earned $$....all claim to do this do that....but
got proof a not.....
Drive less lor, if you really cannot tahan it.....
