Saved RM383.56 this month.
Spend RM4 on front left low light.
Balance of RM556.35 of expenditure on maintenance to be contra off.
Progress is faster this month due to petrol price hike.
RON97 will not costs RM2.05 per liter.
I maintain using price of RON97 even when RON95 is available at a price of RM1.80 per liter so that the variable (petrol used) in my worksheet maintain the same instead of changing from RON97 to RON95.
Also, I've heard that RON95 is not so good as the performance of the car would drop eventually increasing the frequency of pumping petrol.
Few more days and I'll have to service my car...
So, expenditure would eventually slow down the ROI.
I only hope that the service do not costs much...
