The coolant over-flow bottle in my 2016 Honda CR-V has always been exactly at the low mark ever since I bought it in February of 2020 with 19,877 miles on it. Yesterday when I looked at it it only had about 1/4 of an inch of coolant in that over-flow bottle, so during the last 3 weeks it has lost about 4 or 5 ounces of coolant. I had it parked facing up hill and coolant is heavier that oil, so if there were coolant in the oil it would sit in the bottom of the oil pan, and because the oil pan drain bolt is on the bottom back of the pan that bolt is on the downhill side when the vehicle is facing up hill. I even raised the passengers front side so the back side of the pan the oil drain bolt is on would be the lowest point, and let it sit like that for an hour and a half. And the vehicle has not been started in 2 days so if there were any antifreeze in the oil it should have settled near the oil drain bolt. Then I drained 9 ounces into a glass jar with a big funnel duck-taped to the top of the jar. I did not see any antifreeze coming out the oil drain hole, and the bottom of the jar does not look any different then the rest of the oil in the jar. So I suspect there is no antifreeze in the oil.
I want to test the oil by heating a small stainless steel pan and putting about 1/2 an ounce in the pan to see if water boils off.
The oil is Honda 0W-20. From what I can find, it looks like the flash-point is 425 F.
I have an IR temperature reading gun, and a small stainless steel pan that is about the size of a cupcake, but narrower on the bottom and wider on the top. I can pre-heat this small pan with an electric stove and quickly remove it and add the oil to see if water boils off.
What I need to know is what temperature should I pre-heat the stainless steel pan to for doing this test?
And yes I do have a fire-extinguisher handy ( actually 2 of them ), though if it catches fire only in the pan I will just put the pan in a sink.
