While I empathize with the OP, I also feel that it is time for him/her to educate himself/herself about things automotive.
Ergo:
>Check your oil dipstick at least every couple of weeks in order to maintain the crankcase oil at or near the full mark. Ideally, as soon as the level drops by 1/2 qt, you should replenish the oil. NEVER allow the level to fall more than 1 qt below the “full” mark. In fact, your Owner’s Manual instructs you to check the oil every time that you fill the gas tank. How often do you check the oil dipstick?
>When an oil pressure warning light starts glowing on your instrument panel, that should be interpreted as, “Pull over immediately, or as soon as it is safe to do so, and shut down the engine”. This is also something that is noted in the Owner’s Manual. Driving for more than a few more seconds with that light glowing is likely to cause catastrophic engine damage.
>After pulling the vehicle to the side of the road, the first step is to check the dipstick in order to determine the level of oil in the crankcase. If it shows a very low level, then it is reasonable to get a few qts of oil, and add them–slowly–in order to raise the level on the dipstick to the “full” mark. Then, the engine can be restarted in order to see if the oil pressure warning light turns off. If the light does not turn off, shut the engine down again, very quickly!
>If the level of oil is normal and the oil pressure warning light is lit up, that means DO NOT RUN OR RESTART THE ENGINE! Have the vehicle towed or flat-bedded to a reputable garage.
>The only recourse at this point is to obtain a time machine and use it to go back in time to NOT do what you did. Yes, I realize that this is not possible, but on a car with no warranty, you have no recourse whatsoever, and–in fact–even if the car was still under warranty, if you allowed the crankcase to run dry or if you drove with no oil pressure, you would still not be covered, as this constitutes “owner negligence” (See the first bullet item above!).
Unfortunately, you shot yourself in the foot, so to speak.
Hopefully, you will be more knowledgeable and more responsible with the next vehicle.
Sorry for nothing but bad news!
