1997 Daihatsu Terios
It's really ideal to drive!
My car used half a tank of engine oil in 3 weeks. Is it a problem?
Since two years, I really found my Daihatsu Terios very roadworthy, and it works very smoothly, and with no trouble at all since this problem occurred!
Would you buy another car from this manufacturer? Don't Know

That much oil use in only 3 weeks indicates either a very big leak or severe internal engine wear.
Half a tank of engine oil... um well I'd say yes. I'm assuming you mean it went through a few quarts of oil (I realize your country most likely doesn't use the English system, but I'm from the United States, and I don't know the metric system, sorry.) But yes, using that much oil is a serious problem.
Mine was eating 1 liter oil in 4 days, but I checked the engine. There was oil leakage. Oil from the intake! Will you guess it? 6 holes in the intake. 1 is for anti-freeze (engine cooling, intake controlling), 4 are for air intake to cylinders, the last one is nothing but oil comes out from it. I don't know why Daihatsu made that hole. I changed the intake gasket and oil leaked for 1 day. Then it became fine. No leakage, no eating much oil. Now I add 1 liter oil during 1 month. Because it is small engine and high RPM. Also it's an old engine. I adjusted the valves and then the engine noise decreased.
