I was lucky that i never started the engine with the small amount of coolant inside. When i took the drain plug out the coolant was already at the bottom. So After running the engine for a few minutes after draining out bad stuff and installing new oil i then pulled the drain plug to see if anymore coolant was draining out and there wasn't.

One good thing you have going for you is the coolant is not mixing with the oil and is staying the bottom. After initial hot drain, I would not hesitate to put in inexpensive engine oil and drain it WHEN COLD when the oil and coolant are clearly separated and coolant is at the BOTTOM. Kind of a last purge to flush the residual coolant out. As mentioned above, coolant longterm in the crankcase is not good. You are getting good advice in previous post.. Good luck.

Thanks for the advice ! I will drain again and also pull the filter to check. I don't have a spare new one so i might put the old one back until i get one. I ran the tractor for 20 minutes last night after putting the good new oil in, was going out today and drain out the oil again to make sure it comes out clean ?

Most people don't realize just how bad glycol contamination of engine oil actually is. From Four Lethal Diesel Engine Oil Contaminants



Also from The Effects of Glycol Contamination in Engine Oils

WOW ! thanks for all the good info. I knew immediately when i saw that small amount go in the engine i had a problem. If not for seeing that forgotten washer i would have started the engine with the coolant mixture inside. The Kioti dealer doesn't think much harm was done due to the bad stuff being drained before starting the engine. Time will tell !

I've never done it with a tractor but with the backhoe I unplug the fuel shut off solenoid after an oil change and turn the motor over until the oil lite goes out before starting the engine. 747driver I would be to concerned of having any motor damage as a result of your delema with the antifreeze .

Is there reason to worry about your other engines? Could he have contaminated other jugs of oil?

I'd run it to temperature, then drain the oil and change the filter. You want to make sure there is NO coolant in the oil, period. Coolant is an etchant, and will damage bearing surfaces and worse. It will NOT mix well with oil either, so you want it completely out of your engine.

That's what I was thinking. It's cheap insurance to change the oil again to make sure it's all out.

How did you get antifreeze in your new oil jug again? Someone at your house added it? Why? By accident I hope?
I purchased a gallon jug of mobile 1 oil from Kmart one time and as I was checking out I noticed a small dirty spot near cap. As I looked closer I noticed the cap seal was broken. So. I then opened it to check inside in front of the employee and it was used oil. I'm not sure how this happened but employee said it was not the first time she encountered this. Some one is either returning for refund or a employee is making a big restock mistake of used oil return. Either way watch out when you buy your new oil.

No surprise in this day and age that someone would bring back used oil for a return it for a refund. Same as stealing, people have lost their moral compass.

I've heard that it's best to "prime" your new oil filter when you put one in. Cuts down on the time it takes for the oil to get back up to full pressure. Fill it with oil, then screw it in. Not sure if this really makes a difference but I do it anyway. You may lose a little oil as you tip it, so protect the floor and have a rag handy. Why would someone intentionally put coolant in the oil?

We have a motorhome that uses the same oil ( Rotella 15w40 ). I have a person that helps around the home and he said he had drained some antifreeze which also had mostly oil in it into that jug i used. My fault for assuming that just because the seal was gone it was good oil. I always write 'used oil' on the jugs i pour old in. At most was maybe a pint of anti freeze got put into the engine. I got it all drained out before i ever tried starting the engine. I ran the tractor after putting in a fresh new jug last night for maybe a half hour then quit. This morning i went out and drained the oil again. Maybe a tablespoon of antifreeze came out. I will refill with a cheaper 15w40 and run to temp. Then drain it out after it cools as antifreeze settles to the bottom of the pan ? I think i have gotten lucky....only time will tell. Will keep posting results as they happen.

I really appreciate all the advice everyone has give me !
