vehicle will overheat. just dump the oil and antifreeze , flush engine and refill with clean oil
You have a mess.
If you start and warm up your engine: 1) The oil gets very foamy and mucky, and does not circulate through the engine properly. 2) The water in the antifreeze can heat up until it turns to steam, which expands with great force, and breaks some part of the engine. It's best to have the oil changed. That will empty the engine of the oil and antifreeze mix.
Drain it out.
Even small amounts of coolant in the engine oil will cause damage to internal parts over time. Change the oil and filter now.
you have a big problem
Nothing Nothing
No ! antifreeze is usually mixed 50/50 with preferably distilled water for your cooling system
It will destroy the engine from lack of lubrication and overheating.
If you run it that way you will cause internal damage.
When antifreeze is poured into your oil, it weakens your oil cause it to break down prematurely and can cause your engine to fail by spinning an engine bearing and even smoke. This is also a sign of a blown head gasket.
