Forgot to turn off my car....12hrs later...

[Ya Mar]

Hello All,

This winter the battery died on my w123 so I jump started it and left it running and went inside.

Completely forgot about it. Went out to the barn the next day and found the car still running smoothly as could be. No overheating or anything!

I think that's the longest my engine has ever been run!

Now I have the confidence to take the car on a longer road trip!
