Managed a very stupid mistake: changed the oil on my just-purchased '03 Kia Diesel Pregio on uneven ground. The drain plug on it is on the side of the pan, exacerbating the mistake.
Initially drained only ~3.8L and refilled 7.1L. Manual states 7.1L for a complete change. So the oil was overfilled by 3.3L.
I realize I am an idiot. I didn't measure how much oil was in the drain pan, and I did not expect such a difference from slightly uneven ground.
I started the car with almost a gallon of extra oil in it! The oil light went off and all appeared perfectly fine? Maybe it was running louder than usual, but I could not notice any rough idling. Ran it about 1-2 minutes, shut it off, checked the oil and saw it was all the way up to the bends on the stick! Over the distance between F-L again passed F!
Then, drained about 3.3L, started it again and all appeared OK. Now the oil is at F. I did not see any foaming or evidence of foaming--I am lucky for that!
I am worried foaming occurred during this 1 minute of idling. I have checked the dipstick since then 30x and do not see anything.
Also, now only 68% (7.1/10.4) of the current oil in car is new, assuming it was homogeneously mixed by the second time I drained it. I assume the new oil filter should do a good job cleaning up the old oil, but I am worried I really should change it again soon..?
So what is the proper course of action in this event? *When should I do my next oil change? Immediately? I have 200 miles to the next auto store and I don't want to tow it to a shop.
**This observation is strange to me: When checking the oil, one side of the dipstick is coated in oil way past the full mark, about to the same mark as when it was way overfilled. The other side indicates F. If the dipstick tube was overfilled with oil, the dipstick may be scraping oil from the side of the tube... otherwise I believe both sides would indicate past full if it was dipping into the oil level. This sounds reasonable to me, but I am paranoid that the oil level is still too high. I inserted, cleaned, and re-inserted the stick about 20 times to see if I could get a different result but the same thing always happens: one side oil passed the jagged bends, the other side to the F mark.
***The day after this happened, I encountered this problem: Starter Motor Intermittently will not engage I believe this intermittent problem is the solenoid or a wiring problem, and should be unrelated to the oil change, would that be correct?
****Is it possible the oil foamed and I do not notice it on the dipstick?
Thank you so much if you read through this long-winded debacle!
