Why is my 98 honda civic losing all its oil?

I noticed my car was low in oil so I put 5 quarts in (at once) it was fine until I drove it, I drove at most 4 mikes when I noticed all my oil was spilling out?! I thought it meant my transition was going out but someone told me I was supposed to put the oil in one at a time. Can that really cause me to lose all my oil and why?

A 1998 Honda Civic capacity is 3.8 quarts and that is with a filter change. So you just put in 5 quarts and did not even change the filter. You just overfilled the crankcase by at least 1.5 quarts and that is if it had no oil in the crankcase at all. It may have been only 1 quart low so you could have overfilled it by 4 quarts or svn more. No wonder it was blowing oil out. Adding oil 1 quart at a time or all 3.8 quarts at once makes no difference as long as you do not overfill it which you did. Park the car on a level surface. Drain all the oil out and add 3 quarts of the correct weight oil. Wait 15 minutes and check the oil level and only add just enough to reach the full mark. Adding too much oil causes the crankshaft to make contact with the oil. This will cause cavitation which mixes air with the oil and creates a froth. This froth is a very poor lubricant and will cause serious engine wear and damage. Hopefully you did no damage as you only drove 4 miles.

Your stupidity hurts my brain. That car takes 3.5 quarts to fill it up completly WITH AN OIL FILTER.

Only put in what it takes to bring to full level on dipstick. It might be as little as a pint. Over filling is bad. The original loss could be from loose oil filter, gasket leaks, or consumption. Check level every day until problem is found and solved.

Use the dip stick to check the oil level before you add oil. Add one quart at a time until it comes up to the proper level. If you over fill the crankcase with oil, it will damage the engine.

You put FIVE quarts in at once? That is probably more than the car can hold total. Drain it all out and fill it correctly.
