Congrats on getting G. 
The 5.5K is not so much difference in your repayment if you compare with E.  Dun alang-alang, else regret later...
How much discount they give and any freebies?
The Merdeka promotion gives 2K rebate for Toyota cars.

any 3rd gen vios owner here?...

can share me all of ur FC ?....

my vios was about 270km / RM50 , f***ing damn high !

does the result would be better after my first service ?

what fuel you are using?

mine is only minimized by like around 70%.
knocking sound is due to the lousy engine mounting. can claim at Toyota SC.
yes, first service was mineral for mine as well.
14km/litre is on long distance driving is it?

Don't use petron...
their fuel is first time of my driving life after I use half tank cannot tahan need to pump 97 mix to make my car "drivable".... swt
for this car I personally prefer bhp, then caltex

try to monitor "tuk" sound again after speed bump.. suspect lower arm is the cause for this.

have you changed your lower arm or engine mounting?

sc told me usually they use mineral oil for 1~5k and 5~10k service because it is a waste to force replace shortly for more expensive semi or fully which can actually last 10k, but of course if customer willing to pay more they also happy to sell better oil.

at 10k service it is ur choice to pick mineral for every 5k interval or semi/fully for 10k interval.
