Recheck the oil after it cools off and drain
or fill as necessary. Don't screw the dipstick in
when checking. It is best to run it a bit,
let the oil settle awhile and then check the oil again.
When hot it will spew some oil out the filler as the oil
expands when hot. Don't remove the cap when hot.
Did your cooling fan come on? Also check your coolant
tank level. If yours is just oil cooled then check
the fan on that as well.
Could need some cooling system service if overheating.
A stuck thermostat, plugged radiator or bad water pump
can happen or faulty cooling fan or relays.
Check your coolant tank and keep coolant between the level marks.
See if the radiator is full when it cools off.
