Car overheated - should I change my oil as a precaution?

Installed a block heater in my 2010 Civic Si, (1500 kms), and I let the car overheat slightly while idling while I was bleeding the cooling system - ie: engine got really hot before thermostat opened and coolant reached the boiling point. No resulting damage.

I just changed the oil and filter about 500 kms ago - Mobil1 5w30, Wix filter. Oil looks new and is still at the correct level. Should I change the oil again as a precaution?

Update:

Thanks for all the advice! I had to drain the coolant to install the blockheater, and didn't think it would take so long to bleed all the air out of the cooling system. You can only add a little coolant at a time and it took almost an hour of idling/shutting off/squeezing upper rad hose, etc.

Thanks!!

    I wouldn't. Synthetic oils are very resilient, as you'll note that yours still looks new. Just try not to repeat overheating your engine too much, or burnt oil may be the least of your worries.

  • you were using the block heater and running the engine? why. the cooling system does not need that much heat to burp the air out. on a civic all you have to do is wait for the thermostat to open, then go through the process of burping the thermostat housing.

    Change your oil for what? It didn't overheat, did it?

    You don't use a block heater with the engine running. You do know that, don't you?

    The thermostat opens when it reaches it's opening temperature.

    confident you could, yet they provide you 1000 excuses and reasons as to why they do no longer seem to be to blame. in the journey that your motor vehicle has a substantial leak in the coolant gadget, then the combat is over, they win. yet whilst your motor vehicle does no longer have a leak and the coolant point advance into down through fact of regular positioned on and tear, and that they declare what you stated, then they're accountable for the wear and tear. it actual relies upon on what variety of individual the government is and the acceptance of the agency. a huge agency will artwork with you greater desirable than the little save down the block. additionally, it relies upon on your stick skill to have them pay and what you could instruct to them to instruct that they ignored their household tasks.Be very intense-high quality on the beginning up, yet enable them to know perfect which you assume them to pay for the wear and tear.....KECK

    no because the oil did,nt cause it to overheat. sounds to me like the thermostat was sticking before it opened.
