It would trash the engine bearings real quick. Antifreeze in the oil is a for sure engine getter. I just got done rebuilding a 98 350 vortec that had antifreeze in the oil do to the intake gasket leaking and all the engine bearings were trashed.
Yes, if you drained it out before starting it should be ok.
I BELIEVE straight antifreeze will freeze at 7 degrees Fahrenheit but a 50 / 50 mix is good to around -34 degrees Fahrenheit ( antifreeze and preferably distilled water ) Also , the engine sensors for the engine coolant temperature won't work properly
Anti-freeze disburses heat produced by the engine (via radiator), thus preventing engine from overheating and allowing it to properly function.
The 1997 Saturn used dexcool antifreeze. The chemical compounds are different and should never be mixed, as the engine will no longer cool properly.
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.
I'm not a mechanic / technician but I believe if antifreeze is getting into the engine oil it is because of a bad head gasket , or perhaps the head has warped
Yes , it came from the factory with a 50 / 50 mix of antifreeze and distilled water in the cooling system . The antifreeze in the mixture provides freeze , boiling , and corrosion protection ( the corrosion protection does " wear out " ) The other parts in the engine cooling system , such as the water pump , engine thermostat , engine cooling fan , hoses etcetera also need to be working properly
Don't complain; if the engine isn't leaking coolant that just means everything is sealed up properly.

side affects of breathing antifreeze odor from a cng combustible engine
A Chevy Cavalier can use standard, all-purpose antifreeze, so it's unlikely that the wrong kind was put in. However, if it is not diluted properly and the antifreeze is mixed with more than 50 percent water, the engine can overheat under some circumstances.
A bad head gasket is the most common cause of antifreeze mixing in the oil. The antifreeze will dilute the oil and it will eventually cause your engine to seize up.
