So, in the truck that would be about every 100 miles? lol

My sister only changes the oil after the motor locks up due to having no more oil left in motor... (drained all the oil out and it filled a SOLO cup 3/4 of the way. Wonder why it locked up)

I change mine around every 5k miles. Royal Purple...
