Minimising Car Expenses

As we're coming to the end of the year, I thought it would be interesting to share how much I spend on petrol and CashCard top-ups. I drive daily to work and each day in the weekend to leisure places. 

I religiously recorded each petrol and CashCard top-up for my own analysis.

  • "Litres" is amount of petrol added in one pump. I usually go for N95 full tank. 
    • I used DBS Esso and the vouchers they sent for the first half of the year. After which I switched to UOB OneCard (SPC) since DBS started charging the annual fee and also I wanted to concentrate all expenses into one credit card.
    • DBS Esso allows you to accumulate points for redemption of vouchers later on, hence the steep "71.xx%" discount below.
  • "Nett $" is after all the applicable discounts using the station discount card and credit card and the occasional vouchers. 
  • "KM" is the distance travelled since last top up. 
  • "KM/L" is the distance travelled per litre of petrol -- dividing "KM" by "Litres". This calculation assumes the amount of petrol added to reach full tank all went towards travelling the "KM". 

There are a couple of "breaks" in which I didn't use the car: 1 x 2-week overseas vacation, 1 x 3-week overseas trip, 1 x 3-week ICT and 3 x weekend overseas trips. That's a total of about 65 days or 2 months. This is an unusual year in which I had quite a lot of "breaks".

Average cost per month is $1349.41 / 10 months = ~ $135 / month which is slightly higher than my average ez-link card consumption per month (about $120) in the past.

CashCard Top-up

I hope I didn't miss out any transaction. I only started to use the vCashCard towards the end of the year and only if I can remember to pull out the CashCard before passing through an ERP gantry. 

Average per month = $850 / 10 months = $85 / month

Moving on, I will avoid the city area as much as possible to save on ERP fees.

Reflection on owning a car in the most expensive city

Mr 15 HWW has kindly referenced my previous articles on car ownership at https://www.my15hourworkweek.com/2018/08/07/4-insights-for-potentia...
