i thought w30 is for 3 cylinder car
if persona use, exhaust no smoke ka? engine sure loud and eat oil..
the most expensive mobil1 also 0w50
recommended for campro is 20w50

means pickup faster??? compare to w40/w50??..or just the pedal lighter??...and wad bout fuel consumption??...

try tighted d belt a bit a c~
if still got sound only change lo~
if u maintain it well add water every once a month or 2 it can stand up to 3yrs~

calling persona se owner..
so far.. how the leather seat?

under hot sun... does it really burning the skin? let say example, under hot sun for 2hour on noon time?

normally how hot is the "hot"? 

some forumer say that hline and se are tinted.. isnt true?

if there are tint by proton d, do you guys go tear it off and go for better solution like vcool or aircool?

thanks
