thanks PK
Could be a bad oil pump or worn engine.
Does it mean my engine is going to be ruined...
the oil signal lights in last week because the loose oil cover. And I was driving more than 200miles after the oil light firstly appears.
So, now I guess that my engine is sort of damaged....
Does anybody know the repair cost?
Your original post states that you checked the oil "& there was almost no oil in the tank" (i.e. - I assume the oil level was low?
If that is the case, I would suggest immediate refill to the correct level, (and check the oil light then) and also investigate why the oil level is / was low.
have solved, it is sort of leakage...thanks
