soufcarolina29 is correct about it being a head gasket or intake gasket. And you should have it checked and repaired as soon as you can. Any garage that says you need a new engine, don't deal with. However if you run it to long you can and will do enough damage to the engine that you will need a new engine.
It was just a coincidence. If you had been later getting the oil change it would have happen before hand. There is no set time or place that a head gasket or intake gasket or for that matter any gasket or seal in an engine to decide it has had enough and it fail.
