What happens if you drive without your oil cap on?
Driving without an oil cap is unsafe for your vehicle and can quickly lead to irrevocable engine damage. Without a seal, the oil can leak into the engine compartment. Due to a lack of lubrication, your engine may overheat. This can cause it to seize, requiring engine replacement.
How long can a car run without oil cap?
Most engines have a bit of pressure inside from combustion. This can escape out the missing cap tube, taking along oil with it. Should every last drop blow out, the engine will run a couple miles to 10 or more before internal parts show a strain. Installing 5 quarts oil may help recovery.
What should I do if my oil cap falls off?

Why do you put an oil cap on an engine?
The manufacturers put the engine oil cap for some specific reason. The oil inside the engine lubricates the parts and cools it down in case of overheating. Some parts like pistons, nozzles, valves, and rings heat up when running for long. The oil keeps the engine temperature normal.
How to clean an oil cap off a hire car?
No need to steam clean the engine. Just get some degreaser in a bottle spray it around the engine (not getting too much on the altenator and fuse box) then clean off with a sponge and rinse. Job done. I’ve picked up a hire car before and got about 120 miles through the Highlands before the lights on the dash came on.
