Please I need urgent advice,
I changed my engine oil on the 7th of July, immediately I got home same day I noticed where I parked was filled with engine oil, so, I went back to the mechanic, after checking he said it was the oil filter that was not lock properly so, he tightened it then I left...... The same thing occurred the next day I went back and he advised I buy another oil filter which I did and one litre of engine oil just to top it, that issue was resolved..... But now I am worried because I feel the one litre of oil I bought did not gauge it to the expected level, can I buy another litre to gauge the expected level after 12 days (167km), because somebody told me it's very risky to do that, since I have driven the car for some days.
NB... The problem of oil leakage has been resolved

Buy 1 liter.it doesn't mean . 3 weeks .1 weeks.1week. Don't mind them. They want u to damage your engine. Top up and fire down

Oil doesn’t gauge to full diesn’t meab there is no oil in the engine. As far as oil is in between that mark you are good.

Your car is ok now, the mechanic just deh eat you office and refused to tighten the down nuts very well.
