Reader Question: We found our oil cap in our driveway. My wife had an oil change done the day before, she drove approximately 25 miles without the cap on.
We checked the dipstick then and found it in the safe zone. My wife thinks the car bogged a little on her way home.
Can you tell us, if any possible damaged occurred to our vehicle?
Your fine, but make sure there is not a problem with cap so this does not happen again. If this is a small engine like on a Japanese vehicle, it could have affected engine performance but did not do any damage to the engine.
My guess is the oil change guys just forgot to re-install the cap.
