Well, fix your broken car. Oil's not your problem.
How do you figure its "broken"...?? Runs fine gets over 23mpg in town..
You arent getting heat, thats a problem.
Atleast thats what I gather from your recent posts. A coolant flush, heater core flush and new thermostat might fix it, or else it may be a blend door problem.
You're asking if oil is why your car is acting broken. Like asking if suede is the reason your kid has a learning disorder.
