The cost of the oil for the Honda was $35.00 and the cost of disposing the used oil drained out of the Honda was $36.50! It cost more to dispose the oil (I am assuming it is because of the environment and all that) than to buy 4 litres of new engine oil.

There I go again, making comparisons to Malaysia and Indonesia. In Malaysia, most garages (Kiwi for workshop) will store the oil to be disposed off in a proper manner..hopefully but don't charge you. In Indonesia most garages will make money out of selling the used oil to some entrepreneur who will convert it to something saleable and sell it. So they make money from selling you the new oil and again from the sale of the used oil.
If you had followed my blog, I bought a Ford Laser sometime in November last year. I filled it up (the tank I mean) a few days after I bought it. It has been 2 months since and the price of fuel has gone up 5 times and down twice and my tank is still not empty! How economical is that?
