Question by John C: 2 oil bolts to change oil on a car?
Hi, i have a mitsubishi lancer 1999, 1.3 .
only brought from a friend. i wanted to change the oil, so under the car i looked and saw a bolt which said “oil”. i opened it and collected only about HALF liter of oil(?) the came out, it was very yellowish. After i looked for the oil filter and saw it was at the other side of the car. (the left) unscrewed that replaced it to. poured oil into the engine and left it run. the dipstick showed it too full. just for pig iron i unscrewed the bolt at the right of the car underneath which said “oil” and nothing came out after pouring about 3 liters in. i drove around a bit (thought it might need to run through) and unscrewed it again and nothing coming out. the dipstick said way too much. looking under the car again i saw another bolt next to the oil filter. this is the oil sump bolt. the oil gushed out. all 3 + liters.so i had to go buy more oil lol. so my question is, what the hell was the bolt over the right underneath of the car that said oil on it??

maybe you drained the gear oil the first time, its normally yellow ish but i would expect a few litres to pour out! you beta make sure your car has gear oil in it as this will lead to gearbox failure if its not filled up to the correct level!!
Hi

Little knowledge is dangerous. You ruined your car’s engine by putting excess oil in it.
you have a dual sump oil pan, its like a fuel sediment bowl.yes you have to pull both.
Walk, or take the bus to the library and look in Chilton’s Auto Repair manual. You may have drained the differential or gearbox. The engine oil drain plug will be at the bottom of the engine oil pan. I know you can find rthe engine. Look under just that thing and there will be a pan with a drain plug on it. It will let out about 4 quarts of black oil. Get some oil to replace whatever you let out. You may need a pump or siphon to do that. The parts store folks will show you what you need.
it was most likely a gearbox plug you pulled first. these cars have yellow fluid in them. you didnt ruin your engine from too much oil unless it lost oil pressure due to aeration.you would have known via either gage or warning light.
