Oil was just changed a month ago. Message came over the message board on the car"turn off engine-oil pressure low" checked the oil, no oil on dip stick"didn't see any oil spots on the drive way" took off the oil cap to put oil in and found water or coolant mixed in with the oil. Took off the coolant hose and same lit brown mixture came out. Can any one give advise one what can be causing this problem. Unemployment ran out- garage door guy by trade.
Thanks

Are you overheating? Your coolant is mixing with oil it is leaking somewhere.
